One last view of the scene. The distortion and blur still look very nice. A simple particle system scatters a handful of gray and black pixels across the view, resembling ash blowing in the wind.
The scene with nice distortion, now also with a subtle blur effect. The blur is synced with the distortion so that larger waves blur more than smaller ones.
The original scene again, now with a much more pleasing distortion effect. It is easily visible around the edges of the lava, and rises above the top edge by a tile or two. The pattern also feels more organic, and has a better distribution of high and low distortion values. It feels like a reasonable facsimile of heat distortion.
A montage of all the previous clips, showing the scene change through iteration.
The same view of the mask channel. This time the mask is blurred. It almost looks like smoke.
A black-and-white view of a flowing perlin noise texture that has been masked to the shape of the lava tiles.
In the same scene, the distortion is now contained to the lava tiles. But so contained that it's easy to miss that anything is happening at all.
Updated shader code with a new depth conversion formula: depth * (zfar - znear) + znear + zfrom
A snipped of GML code. A call to "matrix_build_lookat" is passing -10 as one of the parameters.
A log showing several layers being moved to specific depths. Rocks_2 is moved to depth 5272. Lava is moved to depth 5282.
A debug view of the same "fire zone" scene. Objects are highlighted in red or green, and tile layers are shown in shades of teal. The mouse hovers over some lava tiles, showing the number "5292"
Another shader excerpt. This one writes the "originalDepth" float into the rgba channels of the output.
A zoomed view of the previous clip, highlighting that the distortion is on the rocks instead of the lava.
The pixel art scene again. The previous distortion is almost completely gone, though looking carefully reveals a small amount on the left of the screen, on some rock tiles.
A screenshot of code from a shader. The depth conversion formula is "depthSample.r * (zfar - znear) + znear"
The same scene, but now the distortion is a bit more random and organic feeling. It's still a little much, tho
The same scene as before, this time with a horizontal sine wave repeating across the screen. It's enough to make you sick.
A fire-themed zone in a top-down pixel-art game. The lava looks nice.
