Play appropriate animation based on character's direction (2D point and click)

Questions & Answers
1

I have a simple script to control player movement:

void MovePlayer(){
	if (Input.GetMouseButtonDown(0)) {
		target = (Camera.main.ScreenToWorldPoint(Input.mousePosition));
		target.z = transform.position.z; 
	}
	transform.position = Vector3.MoveTowards(transform.position, target, speed * Time.deltaTime);

	PlayWalkingAnimation();
}

This enabled me to simply click my mouse anywhere on the screen, and the Player will move to that point.

I have four walking animations (NWSE) that i’d like to play depending on the angle the Player is walking in…if that makes sense…

void PlayWalkingAnimation(movementAngle){

    //What is movementAngle???

	if (movementAngle >= 45 degrees && movementAngle < 135 degrees){ 
		direction  = "walking north";
		anim.Play (direction);
	} else if (movementAngle >= 135 degrees && movementAngle < 225 degrees)){ 
		direction  = "walking west";
		anim.Play (direction);
	} else if (movementAngle >= 225 degrees && movementAngle < 315 degrees){ 
		direction = "walk south";
		anim.Play (direction);
	} else {
		direction = "walking east"; 
		anim.Play (direction);
	}
}

I’m not sure how to get the angle I’m moving in, and if there is any math that might be involved.

Also my if-statements might not be spot on, but this is the general idea of what I’m trying to do…

You should use a blendtree, that way you wont even need to write code to get this to work!

Good luck! :slight_smile:

Essentially you make a 2D blend tree, with a point at the top bottom left and right, and one in the centre for your idle animation. You then assign the animations to each of the slots, and give a -1 +1 in the X / Y field respectively to say “this animation is for when we are moving left on the X axis” etc.
