[AS1] Platform game help

Well, I've got this code here for my character. It's instance name is 'circle', though the character itself is animated, that's just to keep it simple.

PHP Code:

onClipEvent (load) {
     fall = false;
     _name = "circle";
     jump = 0;
     speed = 6;
     jumpheight = 11;
     maxfall = -54;
}
onClipEvent (enterFrame) {
     xmin = getBounds(_root).xMin;
     xmax = getBounds(_root).xMax;
     ymin = getBounds(_root).yMin;
     ymax = getBounds(_root).yMax;
     if (Key.isDown(Key.SPACE) && fall == false && jump == undefined) {
          fall = true;
          jump = jumpheight;
     }
     if (jump<>undefined) {
          if (jump>maxfall) {
               jump--;
          }
          _y -= jump;
     }
}
onClipEvent (enterFrame) {
     if (Key.isDown(Key.LEFT)) {
          _x -= speed;
          if(_xscale==100){_xscale=-100;}
     }
     if (Key.isDown(Key.RIGHT)) {
          _x += speed;
          if(_xscale==-100){_xscale=100;}
     }
} 


Now, this makes the character land on a platform and turn around fine, though my characters movie clip is one frame long, and therefore animated within itself(you know, when you double click). And the character keeps walking no matter what button you press(or don't press). So I need a code to make the character stop walking when no buttons are pressed.
Thanks.

PS. The platform code I have is this:

PHP Code:

onClipEvent (load) {
     activated = false;
     down = false;
}
onClipEvent (enterFrame) {
     _root.report.text = Math.round(_root.circle.yMax)+" "+Math.round(yMin);
     xmin = getBounds(_root).xMin;
     xmax = getBounds(_root).xMax;
     ymin = getBounds(_root).yMin;
     ymax = getBounds(_root).yMax;
     if (_root.circle.xMax>xMin && _root.circle.xMin<xMax && _root.circle.yMax<yMin) {
          if (_root.circle.yMax-_root.circle.jump*2>yMin) {
               _root.circle._y = ymin-_root.circle._height/2;
               _root.circle.jump = undefined;
               _root.circle.fall = false;
               activated = true;
          }
     }
     if (Math.round(_root.circle.yMax)>Math.round(yMin)) {
          if (hitTest(_root.circle) && _root.circle.xmax<xmin) {
               _root.circle._x -= _root.circle.speed;
          }
          if (hitTest(_root.circle) && _root.circle.xmin>xmax) {
               _root.circle._x += _root.circle.speed;
          }
          if (hitTest(_root.circle) && _root.circle.ymin>ymax && _root.circle.jump>-1) {
               _root.circle.jump = -1*(_root.circle.jump);
          }
     }
     if (activated == true && not hitTest(_root.circle) && _root.circle.jump == undefined) {
          _root.circle.jump = 0;
          activated = false;
     }
     if (hitTest(_root.circle) && _root.circle.ymax>ymin && _root.circle.jump<>undefined && _root.circle._y<_y) {
          _root.circle._y = ymin-_root.circle._height/2;
          _root.circle.jump = undefined;
          _root.circle.fall = false;
          activated = true;
     }
     if (_root.circle.ymax-_root.circle.jump>ymin && _root.circle.xMin<xMax && _root.circle.xMax>xMin && _root.circle.jump<>undefined && _root.circle._y<_y) {
          _root.circle._y = ymin-_root.circle._height/2;
          _root.circle.jump = undefined;
          _root.circle.fall = false;
          activated = true;
     }
} 


Maybe that can help......

Anyone? C'mon, SOMEONE must know.

[speedlemon]

try using code tags.
it makes it a little easier to read.

[speedlemon]

PHP Code:

onClipEvent(keyUp){
     gotoAndStop(1) //or where ever your standing still frame(s) is/are
} 


should do the trick

[kristof88]

Thanks, though it should gotoandstop on the first frame of the movie clip...how do you do that?

What you should do is to insert a stop command in the first frame of your character.
Then in the characters enter frame event handler you would test for the key down.
If the key is down you tell the character to go to the next frame and stop.
Else you don't do anything (and it stays in place).
Remember that you need to test for the last frame of the character animation so that you can circle back to the first frame.

Ideally you should have the animation connected to the speed of the character and not the key (it kind of depends on the game physics, but I noticed a speed variable in your code).

The following is code from a game I made that uses this approach.

// Updating runners visiual aperanc.
if (!(runner_mc._currentframe == RUN_END) && speed > MIN_SPEED)
{
    runner_mc.nextFrame();
}
else if ((runner_mc._currentframe == RUN_END) && speed >MIN_SPEED)
{
    runner_mc.gotoAndStop(RUN_START);
}

as far as i know it should anyways, but if it isnt -
_root.movieclipnamegoeshere.gotoAndStop(1)

[kristof88]

PHP Code:

onClipEvent (load) {
fall = false;
_name = "circle";
jump = 0;
speed = 6;
jumpheight = 11;
maxfall = -54;
}
onClipEvent (enterFrame) {
xmin = getBounds(_root).xMin;
xmax = getBounds(_root).xMax;
ymin = getBounds(_root).yMin;
ymax = getBounds(_root).yMax;
if (Key.isDown(Key.SPACE) && fall == false && jump == undefined) {
fall = true;
jump = jumpheight;
}
if (jump<>undefined) {
if (jump>maxfall) {
jump--;
}
_y -= jump;


}
}
onClipEvent (enterFrame) {
if (Key.isDown(Key.LEFT)) {
_x -= speed;
if(_xscale==100){_xscale=-100;}
_root.circle.gotoAndPlay(2)
}
if (Key.isDown(Key.RIGHT)) {
_x += speed;
if(_xscale==-100){_xscale=100;}
_root.circle.gotoAndPlay(2)
}
} 


That's the code I have now, and a stop command in the first frame of the MC. The problem now is that the MC only plays when you lift the button, and then it only loops once....I've got an idea on how to fix that, though, I just have to put a Gotoandplay the second frame of the MC at the last frame of that MC. Anyways, how can I make the walking animation play while the button is pressed?

Anyone?

Come on, someone has to know.....
