I have researched and cannot find what I am doing wrong. I cannot find a great deal of info on collisions. I am trying to look at sample programs and it seems I have everything in order but the collisions do not work.

My first question is, Can you somehow view a collision box that you created so you can see how it relates to the object/

Second, If I make an object with Anim8or and export it as a 3ds file and then load it. How can I get a collision box to follow it if it is moved.

Lastly, I have attached my code, can anyone see what I am doing wrong? What I am trying to do is when my laser light sphere hits the object basemirror it should rotate the laser light sphere 90 degrees such that it changes direction as if it bounced off the mirror. The mirror is set to 45 degrees.

Also, how do I attach the 3ds file such that potential helpers can run my program without errror?

Thank you in advance,
John

Sorry, I thought collision was not working but it seems my rotation of the sphere is faulty. I did a xrotate and the ball hit the mirror and went down. I just need to get it to bouce in the correct direction now.

Thanks anyway and I hope I did not waste anyone's time.

Peace!

OK, here it is, I thought the yrotate was cummulative but it is not. It is relative to the creation of the object. I rotated the sphere 90 degrees initially and when it hits the mirror I want it to yrotate 180 not an additional 90.

Look an example of a rebound from my library DBEMathsLib. It is not the answer to your question, but it can help you.

We built a DLL library to handle fast and accurate collisions for DBC and DBPro. It is worth a look. Link to our website is below.
