Vertical Movement Platformer

[scarce]

ok, I'm moving my screen vertiaclly...i have it to very a variabhle is made based on the this.vy movement (*characters jumping variable*) this is a problem because if im not jumping, it's not moving...this is my code


if (stage1._y >= 454.5) {
if (theDrop == false) {
this._y = Stage.height / 2;
yMove = Math.round(this.vy - 1);

_root.platform2._y -= yMove;
_root.platform1._y -= yMove;
stage1._y -= yMove;

}
}
if (this._y <= Stage.height / 2) {
theDrop = false;
yMove = Math.round(this.vy - 1);
_root.platform2._y -= yMove;
_root.platform1._y -= yMove;
stage1._y -= yMove;

if (stage1._y > 454.3) {

this._y = Stage.height / 2;
} else if (stage1._y <= 454.3) {
theDrop = true;
this._y += this.vy;
yMove = 0;
}

}


platform1 is the ground, platform 2 is every other platform...here's my collisions just incase you need to see that too...


function heroCollisions(ob) {
if (ob.hitTest(stopper_scroll)) {
ob.vx = 0;
}

if (ob.vy >= 0.5) {
if (_root.platform1.hitTest(ob._x, ob._y, true)) {
eraserOn = 1;
if (jumper == 0) {
kickStop = false;
bok = false;
ob.vy = 0;
ob._y -= g * 3;
ob.jumping = false;
_global.jumpAttack = false;
falling = false;
}
}
while (_root.platform2.hitTest(ob._x, ob._y, true)) {
eraserOn = 2;

if (jumper == 1) {
jumper = 0;
}
if (jumper == 0) {
kickStop = false;
bok = false;
ob.vy = 0;
ob._y -= g * 3;
ob.jumping = false;
_global.jumpAttack = false;
falling = false;
}
}
}
}


I'm getting confused and frustrated please help me. Any questions just ask HELP PLEASE

Man, I'm getting confused reading that. Let me see if I have this straight.

stage1._y -= yMove;// this is supposed to move your screen

yMove = Math.round(this.vy - 1);// and this sets the speed that the screen moves

ob.vy // so this is the vertical velocity of your character


if im not jumping, it's not moving That does sound like an accurate description of what that code would do, but I have no idea what you would like it to do. Under what conditions do you want it to move, and in what fashion?

Well if I'm not jumping, I want the stage to still move, like walking up an incline. But if I fall of a platform, not jumping I'm trying to get the screen to move back up.

You see, I have the screen movement based on the jumping of the character so it's a fluid screen move instead of a stiff constant speed. I wanna try to get it figured out to where I fall off or walk off a platform it'll still move appropriately. I'm sure the code I have can even be condensed down.

I have a bit of coding that detecxts if your jumping or falling. if the variable for the jump is less then 0 (negative) the status reads rise, if the variable is above 0 (positive) it reads falling, but only if your not on a platform.

I haven't really used tutorials or anything, kinda just figuring out as I go, but this has had me stumped for to long.

So are you trying to give the screen its own velocity or something?

Like, the general approach I'd take is something like this:
if the character's absolute y position is less than a minimum value
move screen down the difference between that y position and the minimum

if the character's absolute y position is more than a maximum value
move screen up the difference between that y position and the maximum
