How cam I programmatically force an avatar to fallFall? about babylonjs-charactercontroller

[ssatguru]

@warrenchopin try setting _freeFall to true instead of false. Let me know if that works

[warrenchopin]

The above error was raised when _inFreeFall= true. I edited the posting correctly.

I tested both _inFreeFall= true and false cases again for sure. The error was raised only when _inFreeFall= true

I thought about three scenarioes to solve this problem.

1. a new command freeFall()
2. a new command moveToPosition(pos, freeFall)
3. a new command moveDiff(vDiff)

The best solution for me is 3. moveDiff(). It is a general function that can be used in many different situations. The problem happened after I overwrote avatar.mesh.position at collision. Overwriting position is pretty aggressive way possibly disrupting CharacterController. moveDiff() will give a way to avoid overwriting mesh.position. Is there a similar function available now?

Thanks again.

You are right in that we do need a function for fall.
Just like we can do jump programmatically , we should be able to do fall too.
This will be usefull for use cases like yours, moving platforms etc.
Let me work on this.

In the meantime try setting CharacterController._grounded to false after collision and let me know if that works.

It worked when I set the two variables together.

cc._inFreeFall= true 
cc._grounded= false

The collided avatar free falls naturally now: The problem solved. Thanks you so much for your help.

Nice.
I just published a new version (0.4.4) with a cc.fall() function to force a fall.
This should also play a fall animation while falling.

@ssatguru: The error was raised later again. I set only cc._grounded=false at this time, and the error disappeared again:

cc._grounded= false

I am not sure whether CharacterController is unstable, or my program is unstable in this case. I will report here if something is wrong again.

Thanks again.
