need more help

hi i have managed to add more code looking at the two example scripts that come with panda3D this is how far i have got but why want he move from the one spot please help

thanks for looking

Please do not double-post!
You can either reply to posts, edit posts or delete posts. But please, don’t double-post if the problem is related or identical.

sorry shud of really jst posted it on the end sorry bit stressed uni work due in tomorrow lol sorry bout that

You don’t leave lost of room to go by. How are you tying to move him? What have you tried?

To move some thing forward:

nope not tryin to move his startPos but move him around at the moment he animates on the spot and floats just above the floor almost like the collision is surrounding him and he cant move i want him to be on the floor and be able to move with the keyboard inputs

I guess you didn’t mix the samples too well, then… I think its the collisions that are wrong, are you sure the bitmasks are set correctly and the collisions get traversed correctly?
