AS3- Multiple platforms help.

[12121231]

Hi everyone working on my game. I can't figure out a method of making multiple platforms.
I'm using this at moment if(man.hitTestObject(ground)) { . What is the coding i need in order to be able to create multiple platforms?

ive become familiar with as3, and yet this question still bothers me. because im sure there is an easier way to do it than how i do.

what i do is just what you did, but a different collision for each platform. and as you can imagine the code gets VERY sloppy and out of control. if anyone knows a better way, please post.

A for..in loop with all of the objects on the stage?

Stick all the platforms in one MC called 'ground' and then use hitTestPoint. Test multiple points if that is not accurate enough for you.

For creating multiple platforms of the same type, and all subject to the exact collision call is very usefull and removes lot of bloated code, so this needs to be work out.

Thanks, Can i have example please, I'm not very good, just started:)

This'll also let you draw irregular surfaces!

Something like:

if(ground.hitTestPoint(guy.x, guy.y, true)){
  ...
};

Bear in mind that hitTestPoint() uses the _root co-ordinate system. If your guy is nested inside something, as will probably be the case if you're using a scrolling screen, you'll need to convert his co-ordinates either manually or with localToGlobal():

absX = holder.guy.x * holder.scaleX + holder.x;
absY = holder.guy.y * holder.scaleY + holder.y;

(Or)

var absPos:Point = new Point(holder.localToGlobal(new Point(holder.guy.x, holder.guy.y));

Thankyou very much Paranoia and UnknownFury, I'll give it a go. Just one more question, this will sound dumb but how do you find out the coordinates of your flash file??

[Paranoia]

If you mean the stage, then everything should be default - (0, 0), 0 rotation, 100% scale, et c. So long as you don't screw that up with a vCam or something.

How can I use hitTestPoint then? Don't I need coordinates of the object????
I dont understand how to find out coordinates of the object.
Or on the stage do I just set the x and y coordinates to (0, 0,)???
