Boundaries AS2

[YoinK]

so yea.. i've got this game i've been working on. It's coming along nicely... but there's one thing i'm having problems with. I have a free roaming character where you control him with the arrow keys. I basically want to figure out how you can set boundaries for him so that he doesn't just walk right above or through things. I have depth perception set up so that he can walk around things.. but i want to be able to set boundaries for where the red line is. Look at this quick sketch i set up for my game. I want to make sure he stays below that red line. What kind of AS2 concept would be necessary for such a thing?????

The concept isn't anymore as complex as to when depth perception isn't involved. He's still moving along the Y axis, I assume the way you're making it look like he's moving away is by scaling him smaller.

Just do a shape flag hitTest against a boundaries movieclip, exactly the way you would with a top down game.

onEnterFrame = function(){
     while(boundariesMC.hitTest(player._x+5, player._y, true)){
          player._x--;
     }
     while(boundariesMC.hitTest(player._x-5, player._y, true)){
          player._x++;
     }
     while(boundariesMC.hitTest(player._x, player._y-5, true)){
          player._y++;
     }
     while(boundariesMC.hitTest(player._x, player._y, true)){
          player._y--;
     }
}

Assuming the registration point of the player movieclip is at his feet, that shouldn't look too bad at all.

okay cool. it works! BUT.. how do i make him stop scaling when he reaches the line?????

i figured this out on my own actually. I set up an equation that adjusts the scaling based upon where the player is at on the Y-axis. :D

Level 59, respect.

You are the only one on NG who has lvl 59 I am right?

That's the best way to do it, rather than changing it on key press.

yea! Another thing is... i have the character set up as an onClipEvent rather than an onEnterFrame because it's a fully customizable character where you can change his appearance. when i have it set as onEnterFrame function it has a delay with the look of the character....
