CharacterController - moving while jumping (movement vector values reset?)

Questions & Answers
1

I have an autorunner movement script - I’m trying to get jumping while moving working with a CharacterController.

I’m seeing this odd behavior: when I jump, the X and Z members of the movementVector in the player script are reset to 0, even though I’m only setting the .y member to jumpSpeed. This means that when I jump, I stop moving and only go up in the Y direction for a bit then continue autorunning.

I found this thread that suggested I separate the vertical speed into another variable, so here’s that version of the movement script. The previous version just set movementVector.y = jumpSpeed directly when the Jump Input was pressed. Both versions result in the same behavior (stopping movement until jumping is over).

void FixedUpdate() {
	if (controller.isGrounded) {
		// Set movement vector to forward transform
		movementVector = transform.forward;

		// Apply player's speed
		movementVector *= _movementProperties.playerSpeed;

		// A grounded character has 0 vertical speed unless...
		_movementProperties.vertSpeed = 0.0f;
		// jump input is pressed
		if (Input.GetButton("Jump")){
			_movementProperties.vertSpeed = _movementProperties.jumpSpeed;
		}else{
			_playerProperties.jummping = false;
		}

	}else{
		// REMOVED - There's a LOT of code here for when we aren't grounded, not relevant 
		}
	}
	
	// Apply gravity to vertical speed
	_movementProperties.vertSpeed -= _movementProperties.gravity * Time.deltaTime;
	// Assign vertical speed to movement vector
	movementVector.y = _movementProperties.vertSpeed;
	// Apply final movement vector
	if (_playerProperties.aliveP){
		controller.Move(movementVector * Time.deltaTime);
	}
}

Input.GetButton will only execute the code inside of its block if the button is held down. Are you just tapping the button or holding the button? Also, you should run your input commands in update not fixed update because update gets run every frame were fixed update does not.
