I think it is the collision that is not working right here is the code

Your code checks for the collision outside of the do-loop. You need to put it inside. SET OBJECT COLLISION ON 1 is fine, it's just the IF statements that need to go inside the loop. What's happening is that each time the do-loop loops, it checks for what you ask it to check. Your code only checks once, and then it starts looping which means that the gravity/collision never happens. Hope that's clear.

You need to change your code from what you posted to the below.

Works fine for me. Maybe it has something to do with your model? Also check to see if you have the latest DBPro version (1.066 I think)

Mr Penguin99:

Please bear in mind that the trial version of DBPro is only meant to give you a taste of what using it is like.

It is well out of date now as the full version you buy has had many updates, whereas the trial is still the old non-patched version.

So, any problems you encounter in the trial should not be taken to mean they are present in the version we all use.

After all, if the trial was as good as the full version, no-one would update to the full version!
