Function Question?

[hooligan2001]

i have a function called moveArr

function = moveArr(){

i was just wondering you know the space in the function between the brackets how do i use that. Is it to declair varibles that are used in the function. And once i have declaired them how do i access them.

Is it anything like

function = moveArr(dir){
if(dir == right){
//do things 
}
}

on a button

on(release) {
moveArr(right);
}

just trying to work out how it works

ThankS in AdvancE

And also what happens if i have 2 varibles

eg

function = moveArr(x,y){
}

how do i set each of these varibles and how do i use them in the function?

You're right. Between the brackets you put the vars you want to pass to the function.

say you have four buttons, left, right, up and down. You colud use:

//LEFT BUTTON
on(release) {
moveArr(-1,0);
}

//RIGHT BUTTON
on(release) {
moveArr(1,0);
}

//UP BUTTON
on(release) {
moveArr(0,-1);
}

//DOWN BUTTON
on(release) {
moveArr(0,1);
}


Then somewhere in your movie (usually first frame) you would have the actual function:

function = moveArr(x,y){
object._x += x;
object._y += y;
}

This would move an object depending on which button was activated because you are sending either 0,1 or -1 to the function and then calling it using x or y depending on the button. The function just moves the object both ways whenever the function is called but won't appear to move if one of the vars passed was 0.

does that help?

Think I rambled a bit at the end
