Map Coding Help

[Pelemus-McSoy]

Hey Newgrounds, how are you this fine evening?

I need help coming up with a more efficient coding method for map movement.

The image below shows what one portion of the map will look like. I can't use hitTest to block the user from going outside of the tan areas, and I do not have the energy/time/will power to make tiny lines to make a hitTest work.

Is there a way to keep the player from going into the black areas, or will the map have to be redrawn?

Thanks for the help, and have a good one.

Yeah, read up on shapeflag hitTesting. If you don't have the will to code, then don't.

I'll give the shapeflag a try.

Thanks.

I've tried using the shapeflag, but it still doesn't seem to work.

This is what I have:

/*Frame-----Dude is the square, and block is the blue area*/
onEnterFrame = function()
{
if(_root.dude.hitTest(_root.block._x, _root.block._y, true))
{
speed = 0;
}
else
{
speed = 5;
}
}

/*on square*/
on(keyPress "<Left>")
{
this._x -= _root.speed;
}
on(keyPress "<Right>")
{
this._x += _root.speed;
}
on(keyPress "<Up>")
{
this._y -= _root.speed;
}
on(keyPress "<Down>")
{
this._y += _root.speed;
}

I have the understanding that shapeFlag is meant for one point only...will that render this code above as useless?

You could look over here

Thanks, but unfortunately I'm working with AS2...or will that code work too?

Mouse maze or arrow keys?

[Pelemus-McSoy]

Arrow keys.

/*movement code*/
onClipEvent(enterFrame)
{
if(Key.isDown(Key.LEFT))
{
this._x += _root.leftSpeed;
}
if(Key.isDown(Key.RIGHT))
{
this._x -= _root.rightSpeed;
}
if(Key.isDown(Key.UP))
{
this._y += _root.upSpeed;
}
}

onEnterFrame = function()
{
   if(_root.block.hitTest(_root.dude._x, _root.dude._y, true)){
	   speed = 0;
   }else{ speed = 5; }
   
   if(Key.isDown(Key.LEFT)){ dude._x-=speed; }
   if(Key.isDown(Key.RIGHT)){ dude._x+=speed; }
   if(Key.isDown(Key.UP)){ dude._y-=speed; }
   if(Key.isDown(Key.DOWN)){ dude._y+=speed; }
}

and remove the code on the dude MC

Hey, Pelemus!

You'll want to look up shapeFlag hitTesting for this one. Assuming that the yellow pathways in your post are a movieclip, you can simply use shapeFlag to move the player back by its speed whenever a side of it is not touching the pathway:

speed = 6;
onEnterFrame = function () {
//if path is not hitTesting the _x of the player PLUS half of the player's width (RIGHT SIDE)
	if (!path.hitTest(player._x+player._width/2, player._y, true)) {
		player._x -=speed;
	}
//if path is not hitTesting the _x of the player MINUS half of the player's width (LEFT SIDE)
	if (!path.hitTest(player._x-player._width/2, player._y, true)) {
		player._x +=speed;
	}
//if path is not hitTesting the _y of the player MINUS half of the player's height (TOP SIDE)
	if (!path.hitTest(player._x, player._y-player._height/2, true)) {
		player._y +=speed;
	}
//if path is not hitTesting the _y of the player PLUS half of the player's height (BOTTOM SIDE)
	if (!path.hitTest(player._x, player._y+player._height/2, true)) {
		player._y -=speed;
	}
};

Thanks. This should be very helpful for me. Thank you very much!

try to look at this FLA

Oh, thank you! I'll be sure to play around with it, see if I can tweak it some for my game...

I owe you guys one!

Use a shapeflag hitTest:
object.hitTest(x, y, Boolean)
In your case, the object is the whole ground / walls movieclip in one. Boolean is true for you. The x and y are coordinates that you use when checking the hitTest to see if the graphic itself touches those points. So use your player's points. Look more about it on AS: Main or anywhere.

Wow, I hate those moments when I forget to scroll down and see if anyone responded. Sorry about that :/
