How do you create exact tilemap collisions in Axe?  My routine to access the value of a tile divides x and y by 4, which is the size of each tile, but means that there is only a collision if it overlaps on the right or is exactly aligned.  It does not register collisions on the left.  How can I register a collision on any overlap?

but collision s the most complicated!, Damn!

Tile based works perfectly. I use this:

Code: [Select]

:If getKey(2) and (X≠0)
:sub(CC,X,Y,X,Y+7
:!If R
:X-1→X
:End
:End
Just to check for a tile on the left. Now you figure out how to check for tiles in the other 3 directions

Code: [Select]

:Lbl CC
:{r2/8*12+(r1/8)+GDB1}→r5
:{r4/8*12+(r3/8)+GDB1}→r6
:r5+r6→R
:Return


Changed for prettification and I think also speed gain:

Code: [Select]

:If getKey(2)
:If X
:!If CC(X,Y,X,Y+7)
:X--
:End
:End
:End
:
:
:Lbl CC
:{r2/8*12+(r1/8)+GDB1}→r5
:{r4/8*12+(r3/8)+GDB1}→r6
:r5+r6→R
:Return

I just love function based programming so much

And so do I

could someone please show me how to do this in lua?

Same principle, but a different syntax

I'm guessing the *12 was because in an 8*8-tile map, it's 12 tiles wide.  For a 4*4-tile map it's 24 tiles wide.
