legs moving on jump

Blitz3D Forums/Blitz3D Beginners Area/legs moving on jump

Newcomer(Posted 2009) [#1]
I've created a cute little character, and a self-sufficient program that will have him talk and jump, and rotate the camera to change the view. My problem now is that whenever he jumps, his legs move halfway up the body (run program for yourself if needed) anybody have any suggestions?

Gday. I have just changed a few things around. There maybe other ways to do it but i usualy set up globals at the start for collisions as well as the collisions. I am a bit of a noob myself at this so i am sure there are many ways to do it but.. Here you go

;create spike & setup collisions
spike = CreateCone(4)
EntityRadius spike,1.95

;create body parts and ground
eyepivot = CreatePivot(spike) ; you can parent your piviots to other entitys as you go instead of using entityparent
