Internal Character Controller Source Code

Well I am curious if there is a possibility to get hands on the source code of the Character Controller, I want to see how it works, in order to learn it and create my own depending on rigidbody.

Is there any way to get your hands on the code

Greetings Phil

 

Here's what is available publicly, which doesn't appear to be much. The fairly scant source code on the C# side, and the CharacterController.h file, tells me much of this component is implemented on the C side, though I've not really looked through the Unity managed source code before. But you can take a look below yourself.

I have no problem with reading c, but I tried to replace the character controller and run into some issues is there maybe some tutorial that will teach me how to implement such a system properly?

 

The reading c part isn't the issue. Unity only publishes the managed, C#, side of the engine source code. You'd need to enter into an agreement with Unity in order to get access to anything more.

 

the CharacterController class is a wrapper around the PhysX character controller extensions. Basically this:
https://docs.nvidia.com/gameworks/c.../physx/guide/Manual/CharacterControllers.html

The source actually isn't even Unity's, and is from Nvidia/PhysX.

Sadly, Unity also gimps the character controller massively (for example physx supports numerous shapes, not just capsule. And it also supports arbitrary up-axis, not just x,y,or z).

Implementing it yourself is well... not going to be that easy. Considering that it's all tapping into the PhysX api, and Unity does not give you direct access to the PhysX api.

 

Instead of starting from Unity's CC, you could look for other rigidbody-based FPV or 3PV character controllers on the net, find one that sorta does what you want and go from there...

 

Yes I just already used some functionallity from the Character controller in my FPSController, which uses these functions. Probably will do this.

btw thanks for the PhysX Manual I think this would help me understand some systems implemented as the Stepping
