Platform bugs?

[Mr.Pancake]

hi,

im back into game making and im making a platformer again now this code i have now is kind of buggy.
1. it jumps trough platforms.
2.you can press space very often wich results in mid air jumps(looks ugly)
maybe it can be fixed somehow so i only jumps once?

flash attached hope you guys can help :)

thanks in advance

As I am on my brothers laptop and will be untill thursday i would appreciate some raw code :)

use


var gravity:Number = 7;
var scale:Number = _xscale;
var walkSpeed:Number = 6;
var jumpSpeed:Number = 10;
var maxjump:Number = 1;
var step:Number = 10;
var wid:Number = 20;
var jump:Boolean = false;
var noJumpKeyPressed:Number = .5;
var JumpKeyPressed:Number = .9;
MovieClip.prototype.moveWalk = function(i) {
this._x += walkSpeed*i;
this._xscale = scale*i;
};
char.onEnterFrame = function() {
if (Key.isDown(Key.SPACE) && !jump) {
gravity -= jumpSpeed;
jump = true;
}
gravity != 0 ? state=3 : null;
this._y += (gravity<-3 ? (!Key.isDown(Key.SPACE) ? gravity *= noJumpKeyPressed : gravity *= JumpKeyPressed) : gravity++);
while (platforms.hitTest(this._x, this._y-3, true) && gravity>0) {
state = 1;
this._y--;
jump = false;
gravity = 0;
}
if (Key.isDown(Key.LEFT) && !platforms.hitTest(this._x-wid, this._y-step, true)) {
this.moveWalk(-1);
} else if (Key.isDown(Key.RIGHT) && !platforms.hitTest(this._x+wid, this._y-step, true)) {
this.moveWalk(1);
}
if ((Key.isDown(Key.LEFT) || Key.isDown(Key.RIGHT)) && !Key.isDown(65) && !jump) {
state = 2;
}
if (!Key.isDown(65)) {
this.gotoAndStop(state);
}
statetxt = state;
};


just mess with the variables.

i guess that would be very helpfull nathan :D but variables make me puke, can you tell me where to add the stuff :P


edit: oh yeah nathan some parts of your site don't work(give's some text error on the page)
