2D shooting with mobile joystick
Hi! I'm trying to make a 2D shooting game with 2 virtual joysticks. Left one for movement and right one to make the char fire where the joystick is aiming.
I can't make the char fire where the joystick is aiming. I have tried many things but nothing works... don't know what can i do =S
Anyone knows how can i do that?
*If need a example of what i'm talking, check this game https://play.google.com/store/apps/details?id=com.gamelion.MonsterShooter&hl=es
Thank you in advance :)
Hi, could you explain how to get access to the 'position' variable on the Joystick script. I'd appreciate it so much!
I assume you know how to get access to the 'position' variable on the Joystick script. You can use Mathf.Atan2() to set the rotation. The example you gave is 3D, but you write 2D. For 2D, the code will look something like this (untested):
var rightJoystick : Joystick;
function Start() {
rightJoystick = GameObject.Find("RightJoystick").GetComponent(Joystick);
}
function Update() {
var dir = rightJoystick.position;
if (dir != Vector3.zero) {
var angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
}
}
This code assumes the front side of your character is facing right when the rotation is (0,0,0).

that position would be a property of the Joystick. Not to be confused with transform.position. If I am reading his code correctly, he is telling you to rotate the "bullet" object relative to the joysticks position. The joysticks position should be deter$$anonymous$$ed by player input and stored on the joystick script. Which is why he said the code assumes, right facing at 0,0,0. It's just the unit circle. Hope this helps.
