character move on stairs?

[conquerors]

in Counter-Strike, character can climb stairs,How to achieve this effect?

need your help.

my english is poor.

You are probably looking for Inverse Kinematics, not physics simulation.

[kotsoft]

usually you can just gradually increase the z value, or whatever you use for height.

Procedural animation?

[Erwin Coumans]

In many games, the character controller is moving a capsule, sphere, box or other convex shape. This collision shape embeds the animated skinned character.

Climbing on stairs using such simplified shape is done by scanning a collision-free path using shape-traces, going up, forward, down (to check stairs). You can learn more about this by checking an open source implementation in idSoftware Quake engine series.

Counter Strike like uses this approach.

Approaches like Natural Motion that include balancing, IK and powered ragdolls are becoming more popular in the future, but most current games use above simple approach.
It is on my (long) todo list for Bullet to provide such shape-trace based character controller.

sorry for replying this post, it is a little old.

I want to say that it is time to implement the IK effect, I can't wait any more.

I've looked in the quake 3 source, but couldn't find anything. Can you give me some guides, where to look in the source?
