Random Movement Help Please

programming flash
1

Hey everyone, first will you please look at this- http://www.angelfire.com/sd2/flashstuff/project.html

im trying to make some enemies that will move around randomly and NOT walk over the walls inside the movieclip named ‘back’.

now i tried to do this but the guy walks over the walls and stuff, plus he doesnt randomly move, it just moves in the same 3 ways. can anyone please help me out here?

Thank You!!

What code are you currently using on the main character?

What code are you attempting to use on the antagonist?

hi, you can look at the fla here. WARNING- the code is very sloppy and disorganized :slight_smile:

i think it may have something to do with the scrolling because if i test it outside of my game it works perfectly. someone suggested i use localToGlobal. problem is, i dont know what the code should look like then…

Thanks For your help :slight_smile:

oh by the way the code for the guy im trying to add random movement isnt in that fla.

the code is


onClipEvent (load) {
    hitme = 0;
    position = new Array(4, 0, 0, 0, 4, 90, -4, 0, 180, 0, -4, -90);
    positioncounter = 0;
    speed_x = position[positioncounter];
    speed_y = position[positioncounter+1];
    gotoAndStop (2);
    function testhit () {
        // hittest the wall
        if (_root.back.hitTest(this._x+speed_x+30, this._y+speed_y, true) and hitme<>1 ) {
            hitme = 1;
        }
        if (_root.back.hitTest(this._x+speed_x-30, this._y+speed_y, true) and hitme<>1 ) {
            hitme = 1;
        }
        if (_root.back.hitTest(this._x+speed_x, this._y+speed_y+30, true) and hitme<>1 ) {
            hitme = 1;
        }
        if (_root.back.hitTest(this._x+speed_x, this._y+speed_y-30, true) and hitme<>1 ) {
            hitme = 1;
        }
