The View Portal needs to independently render using proper frame rate and smooth movements, with the portal itself smoothly recentering as well.
Writing code

Ariel:
Got it — I’ll target the portal itself recentering smoothly, not just the camera/frame math. I’ll make the View Portal render on its own animation cadence so world movement and portal repositioning can interpolate independently.

I found the View Portal logic in Overworld’s Main.js. The current loop renders the portal, map portal, editor, HUD, cursor, and movement in one pass, and the View Portal presentation is still sticky upper-left rather than smoothly recentering.

J:
By recenter, I mean on the leader-most player in the player unit.

Ariel:
Understood: the target center is the leader-most player in the player unit, so the View Portal should interpolate toward that leader’s world/viewport position rather than recentering on an arbitrary party midpoint or last moved actor.

I’m switching the patch focus to Dungeon’s 2D portal code, not Overworld. Dungeon already has a player-unit leader concept, so I’m wiring the portal center to that leader-most player and making the portal center its own interpolated render state instead of using raw player movement coordinates directly.

J:
Actors should smoothly interpolate position based off their position previous and current Auto-Walk position.

Ariel:
Got it — actor rendering should lerp from each actor’s previous Auto-Walk position to its current Auto-Walk position. I’ll keep logical positions discrete for gameplay, but add render-position interpolation so Auto-Walk motion appears smooth and the portal can track the leader smoothly.

J:
Also, frame-based animations should cycle 4 per tick.

Ariel:
I found that Dungeon already has actor motion objects, but the camera/render center is still tied to the older displayRow/displayCol path. I’m adding a dedicated View Portal center state so the portal follows the leader-most player smoothly while actors keep their logical tile positions separate from render interpolation.

I’ll include the 4-frames-per-tick rule in the same render/animation pass, so movement interpolation and sprite animation cadence are driven by the same tick timing instead of drifting independently.

J:
Auto-Walk should be 1 full tile per tick.

Ariel:
Confirmed: Auto-Walk logic should still advance exactly one full tile per tick. The smoothing is render-only interpolation between the previous and current tile positions during that tick, not fractional game movement.

I’ve confirmed the existing Auto-Walk path already resolves movement as cardinal tile steps, so I’m preserving that. The patch will prevent multi-tile logical jumps from rendering as one glide by normalizing every actor render segment to one tile per tick.

Ariel:
I’ll make this as the next delta after C2-62B. I’ll verify what actually landed in the current files, then adjust the render loop so both actor positions and the View Portal center interpolate between discrete tick positions.

J:
Remember, this should only apply to Actors fully or partially visible in the View Portal.

Remember, this should only apply to Actors fully or partially visible in the View Portal during either the entry or exit tick.

Ariel:
I’ve confirmed C2-62B already added a smooth-render layer, but it still snaps the portal to the moving leader during active movement. I’m changing that so the portal center itself is a tick-to-tick interpolation segment, just like actor draw positions.

C2-62D:

J:
Animation Frames are erroneously in reverse order.

Ariel:
I’ll make this the next serial delta, C2-62D, and keep it narrow: find the animation-frame index math, reverse it back to forward order, then repack only the changed file plus README.

I’ve isolated the likely regression: the 4-frame cadence was based on absolute render time, so the cycle could start on a late phase and appear backward/out-of-order relative to the current tick. I’m anchoring frame selection to the current tick’s own start time instead.

J:
Also, Actor position interpolation is failing.

Ariel:
I’ll fold that into C2-62D too: fix the animation frame ordering and repair actor interpolation in the same narrow runtime patch, with actor smoothing still limited to actors visible during either the entry or exit tick.

The actor failure is in the draw/cull side, not just the motion data: the current portal actor layer can fail to include a moving actor unless its current spatial tile is discovered. I’m changing that layer to consider all actors whose entry or exit tick tile intersects the portal, then interpolate only those.

J:
Don't forget to center the view frame to the leader-most player's interpolated position.

Ariel:
Understood — the View Portal frame should center on the leader-most player’s interpolated render position, not the leader’s discrete destination tile. I’ll make the actor interpolation and portal interpolation share that same tick-progress value.

J:
ticks are step based, the render is interpolated between ticks.

Ariel:
Right — ticks are discrete simulation steps, and render interpolation is just presentation between the previous tick snapshot and current tick snapshot. I’ll avoid changing gameplay timing and make render progress derive from step elapsed time only.

C2-62E:

J:
1. Frame-Based Animations are still in reverse order.
2. Interpolation is still integer-based instead of float-based.

Ariel:
I’ll make this C2-62E and address both regressions directly: force frame indices to advance forward through the source frame list, and remove any integer rounding from the interpolation path until final pixel placement.

I found two concrete causes: actor drawing is still rounded to integer pixel coordinates in the active masked actor layer, and the active actor list is still sourced through a tile/spatial lookup that can snap moving actors to a coarse tile. I’m overriding that layer so moving actors are selected from entry/exit visibility and drawn at float render coordinates.

J:
Remember the frame animation rules:

zero frames: n/a
1 frame: 0,0,0,0
2 frames: 0,1,0,1
3 frames: 0,1,0,2
4 framess: 0,1,2,3

Ariel:
Thanks — I’ll encode the frame selector exactly by those rules: zero unavailable, one repeats 0, two alternates 0/1, three maps the four animation phases as 0/1/0/2, and four maps 0/1/2/3.

C2-62F:

J:
1. Animation frames are still erroneously displayed in reverse order.
2. Animated movement is still erroneously per tick instead of smooth.

Ariel:
I’ll make a C2-62F delta and treat the last two symptoms as proof the active draw path is still bypassing the previous fixes. I’m going to inspect the actual C2-62E delta/runtime code, then patch the live animation-frame selection and the render-time movement path directly.

I found the remaining problem pattern: the runtime still has older cached actor-layer code in the call chain, and active actor motion data is being forced to the destination tile for logic. I’m adding a final render-only layer that ignores those integer/logical endpoints and redraws actors from stored float entry→exit tick positions every frame.

Water in Map - 015 is still animated in reverse order.

Ariel:
I’ll make this C2-62G and focus on Map-015 water specifically. Since actor sprite animation was patched separately, I’m going to inspect the tile/water animation path to find the remaining reverse-order frame selector.

J:
The Editor animates in the correct order.

Ariel:
Good clue — if the Editor animates water correctly, I’ll mirror the Editor’s authored-frame order in the game runtime instead of changing the asset data. This points to Dungeon’s play/render tile-animation selector, not Map-015’s water frames themselves.

J:
Btw, don't forgot doors have a special animation rule.

Ariel:
Memory updated

I’ll include that in C2-62G: tile/water animation should follow the Editor’s forward authored order, while door animation must keep its special rule instead of being forced through the general water/tile frame table.

Thought for 1m 43s

I found the door rule in the GE conditions template: closed/open frame indexes are template-driven, and open doors hold the configured open frame instead of cycling. I’m preserving that path and only changing the general non-door tile animation selector.

C2-62H:

J:
When water first moves into view in map 015, it animates properly, when the player stops walking, the water animates in reverse.

Ariel:
I’ll make this C2-62H and target the split behavior: moving-view water uses one selector, stopped-view water is falling back to a different/reversed selector. I’ll patch the stopped/static View Portal tile-animation path to use the same forward authored phase as the moving path, while leaving doors on their special rule.

I found the likely split: the moving portal path redraws newly exposed water tiles, but the stopped portal path can reuse the cached map layer and only update by its local hash/phase. I’m replacing that with an authoritative animated-tile redraw so visible water uses one forward phase whether the portal is moving or stopped.

C2-62I:

J:
Show me your formula for current frame in Dungeon.

Ariel:
Show me your formula for current frame in Dungeon.
Thought for 48s

The effective current-frame formula in C2-62H is this final override near the bottom of Dungeon.js:

const FRAMES_PER_TICK = 4;

const FRAME_PHASES = [
	[],
	[0, 0, 0, 0],
	[0, 1, 0, 1],
	[0, 1, 0, 2],
	[0, 1, 2, 3]
];

function tickMs(game) {
	return Math.max(1, Math.round(Number(game?.motionDuration || game?.moveDelay || 140)));
}

function animationEpoch(game, now) {
	if (!Number.isFinite(Number(game?.__tileAnimationEpoch62H))) {
		game.__tileAnimationEpoch62H = now;
	}
	return Number(game.__tileAnimationEpoch62H);
}

function forwardPhase(game, now) {
	const tick = tickMs(game);
	const frameMs = Math.max(1, tick / FRAMES_PER_TICK);
	const elapsed = Math.max(0, now - animationEpoch(game, now));
	return Math.floor(elapsed / frameMs) % FRAMES_PER_TICK;
}

function forwardSourceIndex(frameCount, phase) {
	const count = Math.max(0, Math.min(4, Math.floor(Number(frameCount || 0))));
	if (!count) return -1;

	const slot = Math.max(0, Math.min(FRAMES_PER_TICK - 1, Math.floor(Number(phase || 0))));
	return FRAME_PHASES[count][slot] ?? 0;
}

function currentFrame(game, frames, now) {
	const list = frames
		.map(frame => String(frame || "").trim())
		.filter(Boolean)
		.slice(0, 4);

	if (!list.length) return "";

	const phase = forwardPhase(game, now);
	const index = forwardSourceIndex(list.length, phase);

	return list[index] || list[0] || "";
}

So, reduced to the core formula:

phase = Math.floor((now - epoch) / (tickMs / 4)) % 4;
frameIndex = FRAME_PHASES[frameCount][phase];
currentFrame = frames[frameIndex];

Which should produce:

0 frames: n/a
1 frame:  0,0,0,0
2 frames: 0,1,0,1
3 frames: 0,1,0,2
4 frames: 0,1,2,3

Doors bypass this formula through spriteFrameForEntry() and use the special door rule instead.

The formula itself is forward. So if Map 015 water still reverses when stopped, the likely remaining problem is not this phase table, but either:

the water frame list is entering this function already reversed in the stopped map-layer path, or
another stopped/static tile draw path is still bypassing this final spriteFrameForEntryStoppedForward62H() override.

J:
I think it is animating in reverse due to to interpolating between previous and current in reverse order.

Ariel:
That diagnosis makes sense: if the visual lerp uses current → previous instead of previous → current, the motion phase and animated tile phase can appear backwards when the portal stops. I’ll make the next delta by auditing the interpolation direction and forcing render lerp to be entry/previous + progress * (exit/current - entry/previous).

J:
This also explains why the movement is one tick at a time instead of interpolated.

Ariel:
Exactly — reversed interpolation would make the render layer spend the frame interval effectively walking from the new tick state back toward the old one, then snapping forward on the next tick. I’ll make C2-62I by correcting interpolation direction and keeping the phase progress monotonic from previous/entry to current/exit.

J:
Please fix.

Ariel:
I’ll produce C2-62I as the next delta. The fix target is the render interpolation direction: previous/entry tick position must be the start, current/exit tick position must be the destination, and progress must move monotonically 0 → 1 without integer rounding.

J:
I think your time keeping may be a little too overthinked.

Ariel:
Agreed — the timekeeping should be simpler. I’ll collapse it to a straightforward tick-progress value: elapsed since last logic tick divided by tick duration, clamped 0–1, then lerp previous → current.

I found the earlier patch stack did get overcomplicated: multiple overrides are competing, and one of them stamps actor logical position to the destination while render code still derives part of its state from motion timing. I’m adding one final simple override that stores render snapshots once per tick and lerps those snapshots forward only.

C2-62J:

J:
Animations are forwards while moving, in reverse while standing still.

Ariel:
That points to two separate animation clocks: the moving redraw path is using the correct forward phase, while the idle/static redraw path is using a countdown/reverse phase or reversed frame resolver. I’ll make C2-62J by removing the idle-specific animation phase and routing both moving and standing-still tiles through the same forward selector.

I found a concrete mismatch with the Editor: the runtime still has a separate idle phase path, while the Editor uses a simple Math.floor(ms / mapAnimationMs) % 4 phase and then applies the authored frame table. I’m going to make the game use one monotonic animation phase for both moving and idle, instead of tying tile animation to actor/portal movement progress.

J:
Frame based animation is now jittery in Chrome.

Ariel:
I’ll make this C2-62K and target Chrome jitter specifically. The likely culprit is tile animation being advanced from wall-clock time every render frame instead of a stable frame-phase latch, so I’ll inspect the current C2-62J delta and stabilize frame-based animation without reintroducing reverse order.

I found why Chrome can jitter even when order is correct: C2-62J recomputes the phase from high-resolution wall-clock time during render. In Chrome, that can cross a frame boundary mid redraw or skip a phase after a small scheduling wobble. I’m replacing it with a latched animation phase that updates once per render frame.

9. Process Cells as Number
10. Convert Height*Width Cells to PNG

Ariel:
I’ll make this the next delta after C2-62L and target the Sprite CSV loading path. The implementation should avoid line-by-line CSV parsing for sprite data and instead do a fast byte/string pass: header parse, strip CRLF/commas from body, then decode fixed-width 2-hex cells into the PNG buffer.

J:
2 decimal, not hex.

Ariel:
Got it — the body cells are 2 decimal digits, not hex. I’ll parse each 2-character cell with base 10, so "09" becomes 9, "24" becomes 24, etc., then emit Height * Width cells into the PNG conversion path.

J:
2 byte signed Number, not Hex.

Ariel:
Understood: each sprite CSV cell is a 2-byte signed number, not hex and not two decimal characters. I’ll treat the body after the header as byte-paired signed values and convert exactly Height * Width cells into the PNG path.

I need to search for functions or tools that can do this conversion.

The same needs to be done for Map CSV's but as an array, not a png.

Ariel:
I’ll apply both fast paths: Sprite CSVs decode to PNG from 2-byte signed cells, and Map CSVs decode to numeric arrays using the same byte-oriented approach. I’ll keep the output delta narrow and name it with the next serial after C2-62L.

I’ll make this the next delta, C2-62N, and compare the engine’s animation path against the Editor’s known-good order. Since the Editor is correct, I’ll avoid changing assets and patch only the runtime selector/path that still reverses authored frames.

J:
Animations are still in reverse in the engine but animate correctly in the Editor.
The Editor needs to use the Sprite/Map CSV fastload as well.

Got it — C2-62N should do both: fix the engine’s reversed animation by mirroring the Editor’s frame selector, and move the Editor onto the same Sprite/Map CSV fastload path so load behavior is consistent.

I’m going to make the engine animation selector a final single source of truth at the end of Dungeon.js, using the same monotonically increasing phase style the Editor uses. I’m also patching the Editor API so loadMap and loadTile use the fixed-width CSV fast path before falling back to the regular parser.

Thought for 5m 51s

Done — C2-62N delta is valid.

Patched:
public/alpha/Dungeon/2D/js/Dungeon.js
public/alpha/Dungeon/Editor/api.php

Included:
README-C2-62N.txt

Fixed:

Engine tile animation now uses a final forward authored-frame selector while moving or standing still.
Water animation no longer has a separate idle/static reverse path.
Preserved frame rules:
0 frames: n/a
1 frame: 0,0,0,0
2 frames: 0,1,0,1
3 frames: 0,1,0,2
4 frames: 0,1,2,3
Doors still bypass the general animation selector and keep their special rule.
Editor loadMap now uses fixed-width CSV fastload for map.csv.
Editor loadTile / sprite previews now use fixed-width CSV fastload for tile sprite CSVs.
Map row 1 column 3 is preserved as the text-based map name.
Fastload falls back to the normal CSV parser if the fixed format is not detected.
