Okay, here’s the deal: I’m making a platformer/RPG. Here’s my main problem: The platforming doesn’t work. I’ve TRIED to program it so that the elf animates but it’s the background that actually moves, so when he jumps, the background moves.

Instead, he freezes in the jumping pose and doesn’t move.

So yah, if you could give me a hand with the coding.

Umm, have you looked over the internet? And, i’m actually working on a platformer myself: Here’s the jump code:

```
if (jumping) {
	vel_y -= 1;
	if (vel_y&lt;=-10) {
		vel_y = -10;
	}
	this._y -= vel_y;
}
if (Ledge.hitTest(this._x, this._y+this._height/2+15, true)) {
	vel_y = 0;
	jumping = false;
}
```

try changing the \_root.loller1.x to \_root.loller1.\_x , same with the y’s (to \_y)

looks like you are just moving the property x of loller without moving it on stage (\_x)

maybe this will answer your question?

Gah, tried that, still not working. Here’s the Flash file, maybe a look at the whole thing would help. \>\_\<

Alright, I’ve decided to try to use Nathan’s code, but my computer keeps reporting the same syntax error, that being:  
[COLOR=red] **Error** Scene=level 1, layer=Layer 2, frame=1:Line 34: ‘)’ expected  
speed++;

Total ActionScript Errors: 1 Reported Errors: 1[/COLOR]  
Now, the code in question:

```auto
} else if (Key.isDown(Key.RIGHT)) {
if (speed
speed++;
}

```

Now I have a feeling something is missing, so I try:

```auto
} else if (Key.isDown(Key.RIGHT)) {
if (speed<maxmove) {
speed++;
}

```

I get the following error:  
[COLOR=red] **Error** Scene=level 1, layer=Layer 2, frame=1:Line 7: Statement block must be terminated by '}'  
onClipEvent (enterFrame) {

**Error** Scene=level 1, layer=Layer 2, frame=1:Line 62: Syntax error.  
}

Total ActionScript Errors: 2 Reported Errors: 2[/COLOR]

In response to which I try adding a } on the last line.

…And then the entire thing goes to hell. Check the links to see the what I mean. o\_O;

Try this. Not sure exactly what I did but it seems to work.

Geh, it still has some glitches. He only faces right, and only falls when he jumps. \>\_\<

</div>

what I would do, is, make 2 mcs, the characer instance name, c, and the ground, instance name, gr;

then I woukld modify this code;

```auto
sh = 20, c.ysp=4
c.onEnterFrame = function() {
 Key.isDown(Key.UP) && !jumping ? (jumping=true, jump=-20) : !gr.hitTest(this._x, this._y+1, true) && !jumping ? this._y+=this.ysp++ : null;
 jumping ? ((!Key.isDown(Key.UP) && jump<=-3 ? jump *= .5 : null), (jump<=-3 ? this._y += (jump *= .85) : jump>-3 ? this._y += (jump++) : null)) : null;
 Key.isDown(Key.LEFT) && !gr.hitTest(this.getBounds(_root).xMin, this._y-sh, true) ? this._x -= 3 : Key.isDown(Key.RIGHT) && !gr.hitTest(this.getBounds(_root).xMax, this._y-sh, true) ? this._x += 3 : null;
 while (gr.hitTest(this._x, this._y, true)) {
  this._y--, this.ysp = 4, jump=jumping=false;
 }
};

```

See, thing is I’m very new to actionscript, and wouldn’t know what to change. My main problem with that code is that my game is intented to be a sidescroller. \>\_\<

So that the screen follows the character across the level, and that the character us always centered on the screen.
