AS: main, the almighty thread being used by n00bs. and im one of them
well, i was posting threads asking for a code like this, and frankly, i was to lazxy to do it myself. so i finally got enough motivation to get up (more like sit down) and do it my self.
alright, all this really does is have to invisble variables (y1, y2) that start at the top of the movie clip. the keep on going down and down and down, until they hit the ground, and rotate the movieclip to fill the space inbetween
and turns it into a function
mainly used for platformers, and i tested it by using AS: platformer by pyro111 since i was in a hurry.
like always, start out with the onclipevent handler;
onClipEvent (enterFrame) {
function rotateWithGround()
{
// the 'function' part turns it into a function
now time to add the y1 and y2 variables..
var y1 = 0; // starts it at the top of the screen
var y2 =0;
now to make them drop by the _x:
var x1 = _x;
var x2 = _x+ _width;
and now:
// get the left side of characters coords with the ground
while (_root.ground.hitTest(x1,y1,true)== false && y1 <10000){y1++;}
// get the right side of character's coords with the ground
while (_root.ground.hitTest(x2,y2,true)== false && y2 < 10000){y2++;}
then...
var ystep = y2-y1; var xstep = x2-x1;
var theta = Math.atan(ystep/xstep);// currently in radians
var degreeTheta = theta/(2* Math.PI) * 360; // now in degrees
_rotation = degreeTheta;
now this part is optional, but here it goes.
make a textbox, go to properties and make it dynamic text.
below the 'dynamic text' box, in the box blelow, type this in:
thetaText
and now, you have it.
making it a platformer, welll,
thnaks pyro for script
make the character, convert to symbol, give it the instance name "olayer" wihtout the quotes.
give it this script:
onClipEvent (load) {
jh = 15;
grav = 0;
speed = 10;
jumpHeight = 11;
scale = _xscale;
}
onClipEvent (enterFrame) {
function rotateWithGround()
{
var y1 = 0; // starts it at the top of the screen
var y2 =0;
var x1 = _x;
var x2 = _x+ _width;
// get the left side of mario's coords with the ground
while (_root.ground.hitTest(x1,y1,true)== false && y1 <10000){y1++;}
// get the right side of mario's coords with the ground
while (_root.ground.hitTest(x2,y2,true)== false && y2 < 10000){y2++;}
var ystep = y2-y1; var xstep = x2-x1;
var theta = Math.atan(ystep/xstep);// currently in radians
var degreeTheta = theta/(2* Math.PI) * 360; // now in degrees
_rotation = degreeTheta;
_root.thetaText.text = "ystep =" + ystep + " xstep=" + xstep;
_root.thetaText.text = "theta:" + theta + " y/x:" + ystep/xstep;
}
grav++;
_y += grav;
while (_root.ground.hitTest(_x, _y, true))
{
grav = 0;
_y--;
if(Key.isDown(jump))
{
grav = -jh;
}
}
/*
if(_root.curve.hitTest(this)){
_rotation += 40
}
*/
// attempting to rotate properly
if (Key.isDown(Key.RIGHT))
{
_x += speed;
_xscale = +scale;
this.gotoAndStop(2);
if (_root.ground.hitTest(_x, _y+3, true))
{
this.gotoAndStop(2);
}
else
{
this.gotoAndStop(1);
}
rotateWithGround();
}
else if (Key.isDown(Key.LEFT))
{
_x -= speed;
_xscale = -scale;
rotateWithGround();
if (_root.ground.hitTest(_x, _y+3, true))
{
this.gotoAndStop(2);
}
else
{
this.gotoAndStop(1);
}
} else {
if (_root.ground.hitTest(_x, _y+3, true) && !Key.isDown(79)) {
this.gotoAndStop(1);
}
}
if (Key.isDown(79) && !Key.isDown(87) && !Key.isDown(65) && !Key.isDown(Key.SPACE)) {
this.gotoAndStop(4);
}
if (Key.isDown(Key.SPACE) && _root.ground.hitTest(_x, _y+3, true)) {
grav = -jumpHeight;
_y -= 4;
this.gotoAndStop(3);
}
if (_root.ground.hitTest(_x+(_width/2), _y-(_height/2), true) || _root.ground.hitTest(_x+(_width/2), _y-((_height/6)*4), true)) {
_x -= speed;
}
if (_root.ground.hitTest(_x-(_width/2), _y-(_height/2), true) || _root.ground.hitTest(_x-(_width/2), _y-((_height/6)*4), true)) {
_x += speed;
}
if (_root.ground.hitTest(_x, _y-_height, true)) {
grav = 2;
}
}
onClipEvent (keyUp) {
this.gotoAndStop(1);
}
now draw the ground, (lines dont work) make it a moviclip, give it the instance name "ground without qoutes, press ctrl+enter, and there you have it...
thnaks pyro111 for the platformer script
