Impossible to change physic radius of an object in python ?

Hi Everybody,
Is it possible to modify the physic “radius” of an objet with a python script ?
I don’t find it in http://www.blender.org/documentation/blender_python_api_2_65_9/bge.types.html#bge.types.KX_GameObject
If it’s not possible, how to crouch a character without moving its origin ?
Thanks,
Greg

with replaceMesh you can replace the collision mesh of an object, replace when crouched, and revert when standing up. alternatively you could scale.

Use a seperate collision object, and then change the scales, with something like:


radius = 5
col_obj.worldScale = [radius, radius, radius]
graphics_obj.worldScale = [1,1,1]

Ok, thank you, i’ll try

5

Thank you, it’s functionning, but when i do that, the physic seems to freeze : the character is flying, and when i press a keyboard key, it’s falling on the ground… do you know why ?
And sometimes, i fall under the floor… :frowning:

Edit: ok, it functions very well with:


if own["crouching"]:
   scene.objects["Player"].position.z -= 0.1
   scene.objects["Player"].worldScale = [4,1.1,0.4]
   own.worldScale = [1,1,1]
else:
   scene.objects["Player"].position.z += 1
   scene.objects["Player"].worldScale = [1,1,1]
   own.worldScale = [1,1,1]

own is the armature
Player is the collision mesh
