GUI Box to draw Target Lock Icon
Hi,
I planned to use OnGUI function to draw "Target Lock" icon on incoming rockets for FPS game.
this is just an example
Requirement:
1) able to expand in size if the rocket comes near
2) able to track rocket using WorldToScreenPoint function
Any idea on how to do it? Thanks!
You can increase the size of the target lock icon by using
var size = 1/Vector3.Distance(player.transform.position, enemy.transform.position)It will now increase as the enemy gets closer and decrease as it gets further away
For the tracking bit, use:
var position = Data.cam.camera.WorldToScreenPoint (enemies[e].position); position.y = Screen.height - position.y; GUI.DrawTexture(Rect((position.x - (size/2)), (position.y - (size/2)), size, targetSize), texture);
And there you have it :)
P.S. you'll probably need to multiply the 'size' variable by a number so that the target lock icon doesn't increase or decrease too quickly
