Exult Forum

Im going to start making an engine for comptuer science, and was wondering how clipping is handles in exult? Physical clipping.

since U7 is tile based, I would guess that the game checks to see if surrounding tiles are transversible.

on the same level as the given sprite, that is.

Yes but tiles have different sizes and stuff. And walls have there clipping region at the base. And how come you can stand on some stuff?

why is there a but?

I press the up key.

game checks to see if the next tile can be walked on. if not, the sprite does not move north.

a tile may also change the level that the sprite is on in additon to be walkable.

Not sure what you mean by 'clipping'. The notion in Exult is just that there is a rectangle that can be set so that any pixels outside it aren't drawn. But this has nothing to do with the actual 3D world.

Exult (actually U7) is actually a 3D world, but drawn with 2D images. The tiles are 8x8 pixels, but objects aren't constrained to them in appearance. Each object has a 3D tile coordinate, and also has 3 dimensions given in tiles, and this is the information used to determine blocking.
