I have made a character controller and would like some help perfecting it.
When you jump it descends slowly to the ground. I have no clue how to fix this. I tried to increase the gravity, but jitters when on the ground. I also tried speeding up the simulation, but that doesn't speed up the descent my much.
Here is the code:

How can I crouch the object and size the object on the y axis so it will return the correct ray cast response?
Wouldn't you have to size the object then use: Phy Delete Rigid Body then: Phy Make Rigid Body Dynamic Box again?
After figuring out crouching how would I crouch jump?
In halo 2 you would press it right after you jump.
How would I figure out when I would accept the executed crouch jump?
Would I be able to execute the jump when I reach a certain height and will only work if it is under a certain height?
Like this: Crouch Jumping will only work between these heights off the ground: 11 and < 12.
Would this be the correct way of doing this or would timing be used?
Is there a smoother way of jumping? (seems like the impulse of the force is causing the problem) (I don't want to use velocity though. Velocity will cause collision problems.
I also have been trying to figure out how I would hang on a ledge.
I would have to figure out how to calculate if there is a ledge in front of the character.
Then I have to figure out how to grab on it and move down a bit after grabbing on.
After that I would have to figure out how to pull the character up and over the wall.
The last thing I would have to figure out is the character's stamina related to how fast he can run, but that is the easy part.
Thanks,
Dark Fire
My future self met up with one day to teach me what I know today.
