Hello, everyone! I've been trying to figure out how to do this for some time now; and I keep running into things that either don't work or run in RPG Maker VX\Ace.
What I've been trying to do is to modify a simple pixel movement script to allow the player to collide with the objects by, instead of a 32 x 32 tile, the pixel itself using a black and white color map. The reason why is because I am attempting to make isometric-ish maps with both Blender and pixel-by-pixel tracing and tiling.
I don't know if RGSS1 can do this, but I have seen it in RGSS2/3A. I've also seen similar black and white tiling done with H-Mode 7, a limited (but very awesome) third-dimensional script for RPG Maker XP. However, H-Mode 7 used them for a different aspect, but it's kid of the same.
