Shooting To a Target

[glass22]

Hi,

 

I'm looking to shoot a bullet when I click the mouse, I know how to make it go towards the mouse click, but how can I make it carry on past it? is there anyway to set a localX and localY?

the correct way to do that such a thing is not by setting x & y each frame in order to keep the right path, what you need to do is to simply create a bullet, set the initial x & y (player position maybe) and set the direction and speed, and that's it, the bullet will automatically carry on to the correct path, if you are using Phaser then checkout these two examples (you better go through them in order just to understand the principle of shooting bullets in games) 

• Invaders example
• Tank example

You can give the bullet a movement vector that defines the amount it moves each update on the x & y axis.

for eg

function Bullet(){  this.position = {x:0,y:0}  this.velocity = {x:10,y:2}  this.update = function(){    this.position.x += this.velocity.x;    this.position.y += this.velocity.y;  }}

In your case you would want to adjust the velocity according to the distance between the bullets starting point and the co-ordinates of the user click so that it goes in the correct direction but maintains an appropriate overall speed.
