How to draw an arrow from fps contoller

Questions & Answers
1

hello
I would like to know how to attach an arrow to show what direction the fps controller is facing. I am using the below method to get the power I will use to throw the stone. The directional arrow is so i can see what direction the fps controller is facing when I switch the camera view so i still know what direction ill be throwing the mentioned stone. The stone is an object that is thrown at targets.

 void OnGUI() {
        hSbarValue = GUI.HorizontalScrollbar(new Rect(25, 25, 100, 30), Mathf.PingPong(Time.time*5.0f, 19), 1.0F, 0.0F, 19.0F);
    }

I would also like the arrow to change the its size depending on the power off that method.

I dont have a clue how to do this so any help would be appreciated.

Thanking you

As a starting point, scale a box to (0.1, 0.1, 1) or whatever works with your scene. You want it long on the Z axis. Place this in front of your character so that it is pointing forward. Make this a child of the game controller object. You can set the local scale of the box at runtime based on hSBarValue.

transform.localScale = new Vector3(.1f, .1f, 1.0 * factor * hSBarValue);

If this is a permanent part of the game (rather than a debugging tool), replace the box with a 3D arrow object.
