Hi,

I had a search of the forums and couldn't seem to find anything on this... How do I check multiple collisions, without writing them all out? I mean, I've created 5,000 tree's in a 3d world. How can I stop the player running through these?

Without writing
if object collision(1,2) then.........
if object collision(1,3) then.........
if object collision(1,4) then.........
if object collision(1,5) then.........
if object collision(1,6) then.........
.....
....
...
..
.

Thanks for the help in advance

If first of all you don't succeed, it's probably not worth doing.

collide = object collision(1,0)


From the help files:
Quote: "If the second object number is set to zero, the number of the object overlapping with the first object will be returned as an integer value."

Or failing that, you could have used a for-next loop You're new to the forums so I suggest you look up on them if you haven't already, they're very useful.

Oh another quick question. How can I get collision to ignore one? using "collideID = object collision(1,0)"

thanks again

It would be



in this specific case, your code would basically check for any collision at all in the game

You could also turn off the collision so it doesn't even check it in the first place:



Or, exclude it:

Thanks 'TheComet', that's exactly the answer I needed... not sure why / how I didn't think of that though

I only want to exclude a couple of objects so scanning collision on EVERY OTHER ONE would destroy my fps.

If you combine all of your 'collision objects' into one object you'll get an increase in performance. You could just check for a collision with one object.

Thanks for the advice baxslash, but that could be a little hard with an unlimited terrain

But I will merge any collision models where I can!
