Hello @meta_core ,
To rotate your entity you can use this.entity.rotate(), which is outlined in the docs. Simply call the method within your already existing checks for A/D/Left Arrow/Right Arrow keypresses. Let me know if you need further help!

thank you so much for your help. it works fine. but there is another problem. forward and backward (W, S & UP ARROW, DOWN ARROW ) movement positions come to the started position, so I need to update the camera at the live position with the rotation.
(the simple idea of this code is the person can rotate using left & right arrow keys and A & D keys.
W, S, and UP ARROW AND DOWN ARROW keys use to move forward and backward. )
*.user can rotate and move forward and backward at the same time.
could you help me with this?

Hey @meta_core,
I’m not quite sure I understand your question, but if you wish to move your character, you should use this.entity.translateLocal(this.speed, 0, 0);
Replace speed in the above line by whatever variable you are using for speed. This will move the character forward in its local axis (It will move the character toward its front).
Here’s the documentation for this function.
Hey @meta_core,
I hadn’t realised the first time but you are using physics to move your character, so instead of using translateLocal, I would use ‘applyForce’ instead. It works similarly, but instead of simply moving the character, it adds force in the direction you specify.
If that doesn’t work for you, you can try rigidbody.teleport(x, y, z) too. It is similar to setPosition. Here is the docs for teleport.
I am sorry, please check my project and help me to solve this problem
this is my project. https://playcanv.as/p/8d953da6/
I need to add rotate for the left arrow key & right arrow key. ( now it is moving left & right, I do not want this, I need to rotate using the left & right arrow keys)
I want to do this, At the same time, the first person can rotate and move. once the user rotates, the position should be updated and he can walk using the up and down arrow keys. left and right use to rotate not to move.
Hey @meta_core,
If you wish to rotate your character with a dynamic rigidbody, try using rigidbody.applyTorque to rotate it. It should look like this:
if (app.keyboard.isPressed(pc.KEY_A) || app.keyboard.isPressed(pc.KEY_LEFT)) {
// this.entity.rotate(0, this.rotationSpeed * -1 * dt, 0); // If you're using a Kinematic rigidbody
this.entity.rigidbody.applyTorque(0, this.rotationSpeed * -1 * dt, 0); // If you're using a Dynamic rigidbody (Your case)
}
if (app.keyboard.isPressed(pc.KEY_D) || app.keyboard.isPressed(pc.KEY_RIGHT)) {
// this.entity.rotate(0, this.rotationSpeed * dt, 0); // If you're using a Kinematic rigidbody
this.entity.rigidbody.applyTorque(0, this.rotationSpeed * dt, 0); // If you're using a Dynamic rigidbody (Your case)
}
