JavaScript Introducing JavaScript Let's Make a Game Modifying Values

error given

function createPlatforms() { platforms = game.add.physicsGroup();

platforms.create(300, 200, 'platform');
platform2.create(400, 450, 'platform');

I was asked to change line 25 to platform 2 , however, I am still getting an error, is there something else I need to change?

Hey man! I think I know what your problem is:

    platforms.create(300, 200, 'platform');
    platform2.create(400, 450, 'platform');
    platforms.create(100, 450, 'platform');

Because the platforms take up 'space' you can't have them overlap each other. Change their position. Also you've made one tiny mistake the platform you're changing is the string insinde the () I think. So:

    platforms.create(300, 200, 'platform');
    platforms.create(400, 450, 'platform2'); // this I believe.
    platforms.create(100, 450, 'platform');

Let me know if this helps!

Hey Murray! The challenge said:

Let's change one of the platforms to a be different type. Modify the platforms.create command on line 25 to use the string 'platform2' instead of 'platform'.

You were suppose to change the string, not the function name. So instead of:

platform2.create(400, 450, 'platform');

write:

platform.create(400, 450, 'platform2');

Hope this helps!

Thanks, guy's that fixed it .

Hopefully won't make any obvious mistakes like that again.

Thanks a lot.

Haha, trust me, you absolutely will. But we all make mistakes, all the time, push on though!

Honestly like behar said, get used to making silly mistakes. It's part of this aha. :P
