Animating my b3d model

Troubleshooting General Help
1

Hey - I am confused as to how to properly animated a model in game,



the model is from here : PSIONIC GAMES & RETRO VANDAL ART



It correctly loads and skins the model and cycles through all the animations so its working - but how in this case do i set it to , "walk" "attack" "die" etc like it states it can in the readme - or even how do i set the specific frame cycles.



Thanks



Andy

Can nobody help me out with this question!?

Tadaaa.



Things i noticed:

  • MilkToJme.findController(ant); does not work, because it tries to look for a Controller that is attached to the 1. child. But the controller is attached to the base node in this example.

    You can just use JointController controller = (JointController)ant.getController(0); to get hold of the controller.

Core-dump you are a god…why is animating not consistent - for instance such an example doesnt work with my other md2 models - it is a true pest because you end up having to mess around with tons of different attempts to find out what works with each type of model!
