I followed the tutorials to make some 3d stuff, and I was wondering, is it possible to make it so you can’t walk through walls and such? .fla attached
Yeah it is possible to do 3D collissions. It’s rather difficult to explain but there is a process of doing it. First off, you would want to test 3d point allocations to your current position. So therefore, you would have to create a 3dhitTest. This hitTest would scan over not only x and y… but the z plane as well. Just as if you ere doing a complex 2d figure, you would test collission with multiple points, well, with the 3D figure, you would have to test with almost 3-6 times as many points… This could present a problem eh? 
Just some random thoughts.
It’s best to cheat for now and approximate it, in my opinion.
If you want to be more exact: the scaled percentage can tell you approximate Z-Level. So if the X and Y line up, and if Scale is +/- 10% of the position of the object, you score a hit.
If you don’t scale your 3-D this way (faking perspective with scaled movieclips), you can keep track of it with another variable called ObjectZLevel. Check it against something like CurrentZLevel and ProjectileZLevel. I’m working on a new 3-D example to illustrate this better.
