-The reason for this is that we're not yet testing for collision between the ground and the player. We already told Phaser that our ground and ledges would be immovable. Had we not done that when the player collided with them it would stop for a moment and then everything would have collapsed. This is because unless told otherwise, the ground sprite is a moving physical object (also known as a dynamic body) and when the player hits it, the resulting force of the collision is applied to the ground, therefore, the two bodies exchange their velocities and ground starts falling as well.

 So to allow the player to collide and take advantage of the physics properties we need to introduce a collision check in the update function:
-

 <pre class="lang:js decode:true " >function update() {
 
     //  Collide the player and the stars with the platforms
     game.physics.arcade.collide(player, platforms);
 
 }
 </pre>

 The update function is called by the core game loop every frame. The <a href="http://docs.phaser.io/Phaser.Physics.Arcade.html#toc22">Physics.collide</a> function is the one that performs the magic. It takes two objects and tests for collision and performs separation against them. In this case we're giving it the player sprite and the platforms Group. It's clever enough to run collision against all Group members, so this one call will collide against the ground and both ledges. The result is a firm platform:
