constraints on mesh rotation

[DezOnlyOne 6]

is there a simple way to limit the amount of rotation of a mesh? I have a throttle in my project and I have it setup so that I can click and drag it to rotate the lever on the x axis(Thanks to Wingnut and others in this forum).

I want to limit the amount that it can be rotated no matter how much the drag, but I am getting odd results. Is there a way that I can use a clamp to lock the rotation into a certain angle? 

 

PS... to move the throttle, you click and drag from the cylinder objects on the left or right

Thanks in advance

Hello 

why not jsut adding a function to check rotation.x after setting it up? 

 

Like: if rotation.x > Math.PI { rotation.x = Math.PI}

Thanks for the suggestion. I did try that. he odd results are what I was talking about. There is a flickering and the rotation is reset when you click on the throttle again.

Lines 142-161

var rotCfg = {
    min: -3,
    max: 0
}
		
if (currentMesh.name === 'throttle_left_do') {			
	if (throttleLeft.rotation.x < rotCfg.min) {
		throttleLeft.rotation.x = rotCfg.min;
		onPointerUp();
	} else if (throttleLeft.rotation.x > rotCfg.max) {
		throttleLeft.rotation.x = rotCfg.max;
		onPointerUp();
	} else {
		var newRotation = rotationInit - dragDiff.y / 10;
		throttleLeft.rotation.x = -newRotation;
	}
}
if (currentMesh.name === 'throttle_right_do') {			
	if (throttleRight.rotation.x < rotCfg.min) {
		throttleRight.rotation.x = rotCfg.min;
		onPointerUp();
	} else if (throttleRight.rotation.x > rotCfg.max) {
		throttleRight.rotation.x = rotCfg.max;
		onPointerUp();
	} else {
		var newRotation = rotationInit - dragDiff.y / 10;
		throttleRight.rotation.x = -newRotation;
	}
}
