threejs firstPersonControls #252

Open bachy opened 8 years ago

bachy commented 8 years ago

Hello, i now there is an old issue about that : https://github.com/chandlerprall/Physijs/issues/86 but there is no answers and i can't find any answer on web. when i try to add a physijs mesh on threejs firstpersoncontrol, the mesh don't want to move rotation is ok, but x,y,z movement is not working :( is this possible or a will have to code my own control part ? :(

The only way I've found to implement something like firstpersoncontrols in physijs is by never rotating the character mesh, and instead rotating the camera, and giving the character mesh a velocity based on the direction the camera is looking.

@bachy are you using the physijs mesh .__dirtyPosition and .__dirtyRotation flags before updating scene? Using the flags means overwritting the position / rotation of meshes while still keeping collision detection and response.

I have a similar issue. I've created a physijs capsule as the player with a camera attached as a child. Rotating the camera is no problem but I can't get my movement working.

In an earlier build without physijs I could move the camera by the "translateX/Y/Z" commands, which worked fine, because it targets the local coordinates of the camera.

But "translateX/Y/Z" doesn't work for physijs objects so i tried "setLinearVelocity", but this targets the global axis. My player (with attached camera) can walk, but when i turn around my "forward movement" is not forward anymore (if you understand, what I want to say^^).

@Luxilia You recommended 'giving the character mesh a velocity based on the direction the camera is looking' do you or anybody else have a working solution for that?

Implemented something like this in this project. https://github.com/Akimoto873/WebGL-Platformer/blob/master/Platform/WebContent/js/charController.js

Thanks for the quick response. I tried to implement it and it seems to work per se but not for every angle. When I turn to the right everything works fine but on the lefthand side the movement turns by 90°. Which means before I had W=Forward,A=Left,S=Back,D=Right. On the left I suddenly have W=Right,A=Forward,S=Left,D=Back.

That means you missed a part somewhere in my code ^^ Quite a long time since I did this now, but I remember something about changing the priority of the axis'. camera.eulerOrder = "YXZ" I remember I struggled a bit with the problem you mentioned, before I figured out how to get it right ^^

Yey, changing the euler order helped and not it works fine.

Thanks a lot ;D
