I've tried for a while now to get the character controller to work correctly with gravity.

I've searched the forum and tried the examples and ideas people have posted, but none of them successfully get the correct gravity outcome on the character controller.

No matter what I try, gravity will not affect the controller. It affects everything else in the map, but not it. (and it always falls a slow speed, while other things do not)


When I experimented with adding this "phy make rigid body dynamic box CharID" to the controller, it made it unstable and tumbled around as I walked through the map.


So has anyone successfully gotten gravity to work normally with the character controller?

have tried move the mass of the object from the center to its feet, I know someone had do this as a quick fix.

yes i have, and its simple really, u may of noticed that when you move, the character controller falls normally, but when your still, it hardly falls at all,

so in your main loop, move it forward a little bit, then back a little bit, havnt use charactor controller in a while, but i seem to remember it being something like...



That Should Make It Fall With Gravity, Obviously Changing The Amount It Moves Effects The Speed of the falling, and i normally change

Phy Set Gravity 0, -98, 0

Making Gravity 10 Times Stronger, as gravity is 9.81(ish)

Tv Xxx: Yup! That did the trick! Thank you. Its a simple solution, and quite clever.


To those who will run into this problem in the future:

Simply replace all instances of;

PHY MOVE CHARACTER CONTROLLER CHARACTERID#, 0.0

With;

PHY MOVE CHARACTER CONTROLLER CHARACTERID#, 1
PHY MOVE CHARACTER CONTROLLER CHARACTERID#, -1

What I use is the code:

phy set fixed timing 100

to make it seem the gravity is stronger to fit the proper scale in the scene. The reason being, by expierence, is that when you boost up the actual gravity, it will sometimes cause strange behavior towards dynamic rigid bodies like having them jitter up and down even though they are not being touched by another entity. This happens mostly towards larger rigid bodies. I just wanted to let you know about that.

@Quantum Fusion - I used a dynamic object and used:



So the object didn't roll over.

Also, I used phy set fixed timing to speed up the simulation.

Just position the dynamic object at the position of the character controller. (Except for the y coord)



Don't forget to make it the dynamic object also kinematic!

Hope that helps!
