Trying to stop movement...but cant figure it out

1

im trying to make a game where your character is moving around the screen…and i want to make it so the character stops in certain areas…like a cliff, i dont want the character to be able to walk over the cliff…i have been searching for actionscripts and whatnot…and i just cant find it…please help…
flash MX

one method would be to test the position of your character and see if it is over a certain point, for example, say i wanted to make sure that my character wouldn’t go to a point where it’s _x value is less than 100 and it’s _x is greater than 200, i could do something like this:

onClipEvent(enterFrame) {
   if (this._x < 100) {
      this._x = 100;
   } else if (this._x > 200) {
      this._x = 200;
   }
}

thats almost exactly what i am looking for…but can i make that same effect happen when my player goes ontop of another movie clip?ill post some screen shots

this is what the scene looks like…

this is the character:

this is the ditch that i dont want the character to be able to go over top of:

this is the actionscript i have for the character so you can move him with the arrow keys:

onClipEvent (enterFrame) {
	if (Key.isDown(Key.DOWN)) {
		this._y = this._y+10;
		gotoAndStop(2);
	}
	if (Key.isDown(Key.UP)) {
		this._y = this._y-10;
		gotoAndStop(4);
	}
	if (Key.isDown(Key.RIGHT)) {
		this._x = this._x+10;
		gotoAndStop(3);
	}
	if (Key.isDown(Key.LEFT)) {
		this._x = this._x-10;
		gotoAndStop(5);
	}
}
onClipEvent (keyUp) {
	gotoAndStop(1);
}

onClipEvent (enterFrame) {
	if (_root.player, hitTest(_root.holeblock1)) {
		gotoAndStop(1);

	}
}

is there an AS that i can use to keep the character from going overtop of the ditch??

5

do they have to be on the same layer?

6

what about using hitTest()?

7

i dont understand how to make the character stop moving with a hit test

8

you just test to see if the character’s bounding box is intersecting another object’s bounding box.

huh :h:

how the heck do i do that???..

sorry…im just not very good at this stuff :puzzle:

10

if (mcCharacter.hitTest(mcDitch)) {
//put code to stop the Character now
trace(“you hit the Ditch and You Cannot move further”);
}

11

what is the code to stop the character??

i dont want it to say anything…i just want it to stop moving

12 
onClipEvent (enterFrame) {
    if (canMove) {
	if (Key.isDown(Key.DOWN)) {
                prevY = _y
		this._y = this._y+10;
		gotoAndStop(2);
	}
	if (Key.isDown(Key.UP)) {
                prevY = _y
		this._y = this._y-10;
		gotoAndStop(4);
	}
	if (Key.isDown(Key.RIGHT)) {
                prevX = _x
		this._x = this._x+10;
		gotoAndStop(3);
	}
	if (Key.isDown(Key.LEFT)) {
                prevX = _x
		this._x = this._x-10;
		gotoAndStop(5);
	}
    }
}
onClipEvent (keyUp) {
	gotoAndStop(1);
}

onClipEvent (enterFrame) {
	if (_root.player, hitTest(_root.holeblock1)) {
                _x = prevX;
                _y = prevY;
		gotoAndStop(1);
         }
}

possibly a better option here would be to go for the coordinates of the feet, this way his head can go over the cliff, but his feet cannnot - giving the effect that he can walk right upto it.

the way you would do this is:

 onClipEvent (enterFrame) {
	if (_root.player, hitTest(_root.player._x, _root.player_y, true) {
                _x = prevX;
                _y = prevY;
		gotoAndStop(1);
         }
}

hope this helps :slight_smile:

now my guy wont even move.

14

i attached a fla of an example of what i want…

MX2004
if earlier version is needed…just ask…i can add it as MX

15

mx would be useful for me.

16

ok…here is the MX version…

after a long day off frantic searching of how to stop a characters movement…i finally came up with a solution.

here is the code that made the character move:


onClipEvent (enterFrame) {
	if (Key.isDown(Key.DOWN)) {
		this._y = this._y+10;
		gotoAndStop(2);
	}
	if (Key.isDown(Key.UP)) {
		this._y = this._y-10;
		gotoAndStop(3);
	}
	if (Key.isDown(Key.RIGHT)) {
		this._x = this._x+10;
		gotoAndStop(4);
	}
	if (Key.isDown(Key.LEFT)) {
		this._x = this._x-10;
		gotoAndStop(5);
	}
}

and here is what i came up with to stop the chracter from moving:


onClipEvent (enterFrame) {
	if (Key.isDown(Key.DOWN)) {
		this._y = this._y+10;
		gotoAndStop(2);
	}
	if (Key.isDown(Key.UP)) {
		this._y = this._y-10;
		gotoAndStop(3);
	}
	if (Key.isDown(Key.RIGHT)) {
		this._x = this._x+10;
		gotoAndStop(4);
	}
	if (Key.isDown(Key.LEFT)) {
		this._x = this._x-10;
		gotoAndStop(5);
	}
	if (this.hitTest(_root.stopright)){
		this._x = this._x-10;
		gotoAndStop(4);
	}

	if (this.hitTest(_root.stopleft)){
		this._x = this._x-10;
		gotoAndStop(5);
	}

	if (this.hitTest(_root.stopup)){
		this._y = this._y-10;
		gotoAndStop(3);
	}

	if (this.hitTest(_root.stopdown)){
		this._y = this._y+10;
		gotoAndStop(2);
	}
}

finally…now…if anyone knows a better way…please let me know

i want a MC that has an odd shape to it…everytime i try to get the character to stop on a MC it works, but its always a straight line…i want a more organic shape … i know that it is possible…i have seen it done before…but i cant get anyone to hel me out with it…

PLEASE help me…
