[ask] How to Rotate point with image


Recommended Posts

i want to p1 using image not point, and have some images not just p1 maybe p3 and p4 , p2 be a central rotating, can you help me ?

 

var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'try-rotate', {create: create, update: update, render: render });

var p1;
var p2;
var d = 0;

function create() {

p1 = new Phaser.Point(200, 300);
p2 = new Phaser.Point(300, 300);

}

function update() {

p1.rotate(p2.x, p2.y, game.math.wrapAngle(d), true);

d++;

}

function render() {

game.context.fillStyle = 'rgb(255,255,0)';
game.context.fillRect(p1.x, p1.y, 4, 4);

game.context.fillStyle = 'rgb(255,0,0)';
game.context.fillRect(p2.x, p2.y, 4, 4);

}

Create the point objects in the update function, rotate them, and assign the x/y to the image afterwards:

function update(){    var p = new Phaser.Point(img.x, img.y);    p.rotate(p2.x, p2.y, game.math.wrapAngle(d), true);     img.x = p.x;    img.y = p.y;    d++;}

Im not going to answer this but just wanted to say....

Your getting into the realms of "code this for me"....I hate that crap.

If you want people to try and "fix" your code, not "write" it, then show us some code!!!!

Create a simple example in JsBin or CodeIo of woteva and then people like me would be perfectly happy to fix it.

 

@XekeDeath : Love the sig :P  Got a mate who created a career as a coder using that advice....being an Aussie I wonder if he taught you ;)

Positioning sprites is exactly how Xekedeath told you do it. If you want orbiting points and images to boot then do it like that. I done a small example a while ago when playing with point data. Have a look and that should help you.

The planets are all following a rotating point and all i did was pass the X/Y to the image to stick with the rotating point data.
