Both -: (a). Environment to Characters. (b) Character to Character. The Documentation I possess regarding this subject is sparse, to put it mildly. My Questions are-: 1. Which Method is Best? The Method I used in my 2d projects was the "Bounding Box algorithm". Is this method applicable to 3d? I have heard of a "Bounding Sphere algorithm" But I haven't seen/got any info on it. Has anyone any Documentation regarding this Subject? 2. When Creating Environment Blocks in a Modeler are there any Special Considerations to Consider Regarding Collisions i.e. XYZ+- ect. 3. Has any One got any Environment Blocks I could use for Reference? This is so I can see if I created my Models Correctly as I do not have any Info to Refer to. I have a Modeler & I created the blocks in my Project Myself, & I'm not sure I have done them correctly as the Frame Rate is Starting to suffer a Bit When I texture the Objects. 4. Can anyone point me in the direction of any Demos/Information/Sites ect Which Has any Environment Blocks/Collision Detection information? I would be Grateful if any postings regarding this post could be sent to my IP Address as Well as the NewsGroup. Thanks in Advance -- Cobra
