I hate to give out code that takes me so long to write, but I really take pride in this little bit. It's for the sliding collision example, and it impliments the idea of stairs. It takes a lot more to code stairs than you'd think! Anyway, cut the collision code in the sliding collision example (which is this)

position object 11,posx#,posy#,posz#
if object collision(11,0)>0
dec posx#,get object collision x()
dec posy#,get object collision y()
dec posz#,get object collision z()
playergrav#=0.0
endif

And replace it with this:
position object 11,posx#,posy#,posz#
hit#=object collision(11,0)
if object collision(11,0)>0
if get object collision y() then playergrav#=0
if (get object collision x())+(get object collision z())
if ((object size(hit#)+object position y(hit#))-posy#)

oh god it cut off everything, here's the code you should repalce it with:

+ Code Snippet
position object 11,posx#,posy#,posz#
hit#=object collision(11,0)
if object collision(11,0)>0
   if get object collision y() then playergrav#=0
   if (get object collision x())+(get object collision z())
   if ((object size(hit#)+object position y(hit#))-posy#)<40
   posy#=object size y(hit#)+object position y(hit#)+1
   endif
   endif
   dec posx#,get object collision x()
   dec posy#,get object collision y()
   dec posz#,get object collision z()
endif

I think everyone got pissed off when you defended your FPS code. But I defended you. Perhaps they're scared of you.

oh, there's one bug in that which would slow down the framerate. It checks for collision twice in the loop instead of once, and db collision really slows down a program. It works better with:

+ Code Snippet
position object 11,posx#,posy#,posz#
hit#=object collision(11,0)
if hit#<>0
   if get object collision y() then playergrav#=0
   if (get object collision x())+(get object collision z())
   if ((object size(hit#)+object position y(hit#))-posy#)<40
   posy#=object size y(hit#)+object position y(hit#)+1
   endif
   endif
   dec posx#,get object collision x()
   dec posy#,get object collision y()
   dec posz#,get object collision z()
endif

make it with a distance function and use about 10 objects to get a better result for a real world example.

Relying on the DB collision alone is elephant poo, large smelly and tonnes of it.

Er....indi...what? This collision code would be if you made a level out of cubes and boxes, you couldnt check the distance between each one in a loop.

if u replace the object collision with a distance function it will pick up speed dramatically or use a distance function then check for DB collision while turning it on previously and off after the check
