[SOLVED] Problem about moving first person camera

Help & Support
1

I want to make a game that the player can move in a 3d space model. When clicking the floor, the player can move to the point with constant speed, and he can not pass through the wall.

Here is the demo I’ve made: https://playcanv.as/p/Mq9bG9Yd/
Here is the project: https://playcanvas.com/project/485551/overview/house-scene

But I have trouble about moving the player(camera).

  1. As you can see, the camera can rotate normally, but when you click the floor, though the camera can move to the point, the viewport reseted unexpectly.

  2. When the camera collide with the wall, it will fall down, or knock off, or jitter.

How can I solve these problems ?

Problem 1 can be solved by adding a entity as the camera’s parent, and add the rigidbody and collision component to it, remove the camera’s rigidbody and collision component.

When rotating the camera, just set the camera’s local eulerangles, when moving, just apply force to the parent entity or set the parent entity’s linear velocity.

I found a solution for problem 2 at http://answers.playcanvas.com/questions/3080/engine-only-best-way-to-attach-camera-to-a-collision-component, which setting angularFactor to pc.Vec3.ZERO.clone() to prevent rigidbody rotating/rolling.

:sweat_smile: But I am not sure whether this is a right solution, or maybe this is a trick way (especially the problem 2)?
