Oh I explained alittle off. I ment that if you get it its line of sight the enemy spawns. I was alittle to vague on that explanation.

CODE

ffc script SpawnEnemyLineOfSight{
    void run(int radius, int enemy, int spawn){
        ffc f = this;
        if(spawn != 0)  f = Screen->LoadFFC(spawn);
        while(!LineOfSight(f) || Distance(f->X,f->Y,Link->X,Link->Y) > radius || ComboFI(Link->X+8,Link->Y+8,CF_NOENEMY)) Waitframe();
        CreateNPCAt(enemy,f->X,f->Y);
        f->Data = 0;
    }
    bool LineOfSight(ffc f){
        float angle = RadianAngle(f->X,f->Y,Link->X,Link->Y);
        int dir = VelToDir(f);
        return ((Abs(angle) <= PI/4 && dir == DIR_RIGHT) || (Abs(angle) >= 3*PI/4 && dir == DIR_LEFT)
            || (angle >= PI/4 && angle <= 3*PI/4 && dir == DIR_UP) || (angle <= -PI/4 && angle >= -3*PI/4 && dir == DIR_DOWN));
    }
    bool ComboFI(int x, int y, int flag){
        int loc = ComboAt(x,y);
        return (Screen->ComboF[loc] == flag || Screen->ComboI[loc] == flag);
    }
    int VelToDir(ffc f){
        if(Abs(f->Vy) > Abs(f->Vx)){
            if(f->Vy < 0) return DIR_UP;
            else return DIR_DOWN;
        }else{
            if(f->Vx < 0) return DIR_LEFT;
            else return DIR_RIGHT;
        }
        return -1;
    }

ERROR LINE 219 VARIABLE RADIUS IS UNDECLARED.

Can you fix this?

Fixed.

[King Harkinian]

Thank you very much. I'm going to test it now.

[Joe123]

Just realised my angles were wrong, grab it again.

[King Harkinian]

It's working! But I have a question. Can the Phantoms see through solid combos?

[Joe123]

Yes.

[King Harkinian]

I have a problem. The phantoms see link when he is to the left and right of the ffc. Can you make it so you can switch which directions ( turn left and right into up and down) or write a script for these phantoms?

[Joe123]

The ffc is the black circle, and the big circle is it's radius of vision.
When it's facing up, it can see the blue area. Down is red, left is yellow and right is green. If the script is doing anything differently from this, it's going wrong.

[King Harkinian]

It's going wrong. When the ffc moves up or down, I can walk right through it without being seen (I now use this problem to skip the phantom when testing the level. I guess the phantom has terrible eyesight. )! I think there is a problem somewhere in the pixel range/ radius/ direction area. But it could be ANYWHERE in the script.

[Joe123]

Is your phantom moving?

[King Harkinian]

Yeah it is. It has a Y speed of 1, and then I set up some ffc changers tom change its path.

[Joe123]

Well I had up and down the wrong way round so try it again now. That doesn't sound like your issue though.

...and right is green. ...Right? Otherwise I'm confused. Not that I really understand it =p
