Top down Endless Runner - Moving Platform

[GideonSam]

Hi All

I've been working on a top down endless runner , where the player jumps from one platform to another and should not leave the screen.

How to make a platform move horizontally

I'm spawning platforms and adding x and y velocity  its working but is it a right of doing it ? if not how to make it look better

this.initX = this.x;

this.body.velocity.y = -200;

 

platform.prototype.update = function () {

 

if (this.moving)

{

   if (this.x > (this.initX + this.width)) {

                 this.speed = -200;

   }

   if (this.x < (this.initX)) {

                this.speed = 200;

   }

   this.body.velocity.x = this.speed;

}
