Stolen Code (from Tiki Racer)

Some code for gravity, taken from 'Tiki Racer'. Should come in useful. Keep in mind that it's action script 2.

function lastFrame(){

if(this.voodoomask_mc._currentframe == 6){
voodoogod_mc.onEnterFrame = null;
this.voodoomask_mc.armspear_mc.spear_mc._alpha = 0;



var myPoint2:Object = new Object();
myPoint2.x = voodoogod_mc.voodoomask_mc.spearpoint_mc._x;
myPoint2.y = voodoogod_mc.voodoomask_mc.spearpoint_mc._y;


_root.voodoogod_mc.voodoomask_mc.localToGlobal(myPoint2);

vgravity =0.4;
vb =0.03;
vdx = 9;
vdy = -4;
makeSpear(myPoint2.x,myPoint2.y);
}
}

function makeSpear(thex,they){
theClip = _root.attachMovie("spear2","spear2_mc",voodoodepth+1);
theClip._x=thex;
theClip._y=they;
theClip.onEnterFrame=spearMove;
retreatId = setInterval(retreat,1000);
}

function spearMove(){
vdy += vgravity;
this._x += vdx;
this._y += vdy;
this._rotation +=4;
if(this.speartip_mc.hitTest(car_mc.target_mc)){
soundMachine1.attachSound("Coreyjerrhelm Scream2.mp3");
soundMachine1.start();
this.onEnterFrame = null;
this.removeMovieClip();
health_mc.gotoAndStop(health_mc._currentframe + arrowdamage);
}


if(this._y > 430){
this.onEnterFrame = null;
this.removeMovieClip();
}
}

function retreat(){
clearInterval(retreatId);
voodoogod_mc.onEnterFrame = voodooRetreat;
}

function voodooRetreat(){
this._x -= 5;
if (this._x < -80){
this.removeMovieClip();
voodooId = setInterval(createVoodoo,voodoofreq);
}
}


And also:

function lobCoconut(){
var myPoint:Object = new Object();
myPoint.x = ropeswing_mc.monkey_mc.sArm_mc.coconut_mc._x;
myPoint.y = ropeswing_mc.monkey_mc.sArm_mc.coconut_mc._y
/*trace("x: "+ myPoint.x);
trace("y: "+ myPoint.y);*/

_root.ropeswing_mc.monkey_mc.sArm_mc.localToGlobal(myPoint);


/*trace("after x: "+ myPoint.x);
trace("after y: "+ myPoint.y);*/
gravity =0.4;
b =0.05;
dx = -2;
dy = -0.02;
makeCoconut(myPoint.x,myPoint.y);

}



function coconutMove(){
dy += gravity;
this._x += dx;
this._y += dy;
if(this.hitTest(car_mc.target_mc)){
soundMachine1.attachSound("monkey1.mp3");
soundMachine1.start();
theClip = _root.attachMovie("coconutcrack","coconutcrack"+coconutDepth,coconutDepth+1);
theClip._x = this._x;
theClip._y = this._y;
gravity3 =0.9;
b3 =0.05;
dx3 = -2;
dy3 = -9;
theClip.onEnterFrame = crackMove;
this.onEnterFrame = null;
this.removeMovieClip();
health_mc.gotoAndStop(health_mc._currentframe + cocodamage);
}
}
