I'm getting this error:

Looks like it might be some scoping issue with nested for loops.

It happens in this function: (I will mark line 50)

Code: ags

function writeSpriteFont(int fontNum) {
	String fontstring = "";
    int i = 32;
	for(i=32;i <= 126; i++){
		fontstring = fontstring.Append(String.Format("%c", i));
	}
	int w = GetTextWidth(fontstring, fontNum) + 5;
	int h = GetTextHeight(fontstring, fontNum, w) + 2;
	DynamicSprite *s = DynamicSprite.Create(w * 2,h);
	DrawingSurface *ds = s.GetDrawingSurface();
	Rectangle* rects[] = new Rectangle[127];
	String metrics = "";
	ds.Clear();
	ds.DrawingColor = 15;
	int x = 0;
	for(i=32; i<=126; i++) {
		ds.DrawString(x,0,fontNum,String.Char(i));
		int ww = GetTextWidth(String.Char(i), fontNum);
		rects[i] = Rectangle.Create(x,0,ww,h);
		x += ww;
	}
	
	int top = -1;
    int y = 0;
    
	for(y = 0; y <= h - 1; y++)
    {
		for(x = 0; x <= w-1; x++) {
			int p = ds.GetPixel(x,y);
			if (p != COLOR_TRANSPARENT) {
				top = y;
				break;
            }
		}
		if(top > -1) {
			break;
		}
    }
	
	int bottom = -1;
    int start = 3;
    if (top > -1) {
        start = top;
    }
	for(y = start; y < h; y++) {
		bool found = false;
		for(x = 0; x < w; x++) {
                        Display("%d %d %d %d", x,  y,  ds.Width,  ds.Height); // <-- THIS LINE WILL ALSO CRASH IT.       
			int p = ds.GetPixel(x,y); // <-- THIS WAS THE OFFENDING LINE
			if(p != COLOR_TRANSPARENT) {
				found = true;
				break;
			}
		}
		if (!found) {
			bottom = y;
			break;
		}
	}
	
	ds.Release();
	
	if (top > 0) {
		s.Crop(0,top,w,h);
		for(i = 0; i < 127; i++) {
            if (rects[i] != null) {
                rects[i].y = top;
            }
		}
	}
	
	if (bottom > 0) {
		s.Crop(0,0,w,bottom - top);
		for(i = 0; i < 127; i++) {
            if (rects[i] != null) {
                rects[i].height = s.Height;
            }
		}
	}
	
    s.SaveToFile("spritefont.bmp");
    
	//now build metrics
    File *f = File.Open("metrics.txt",eFileWrite);
    for(i = 0; i < 127; i++) {
        if (rects[i] != null) {
            f.WriteRawLine(String.Format("SetGlyph(%d, %d, %d, %d, %d, %d);[", fontNum, i,  rects[i].x, rects[i].y,rects[i].width,rects[i].height));
        }
    }
	f.Close();
	
}

EDIT: Ok no, it's a compiler issue. If i define "p" earlier in the script then it works. Seems that the compiler allows int p to be defined twice (I thought it would be allowed because they are different scopes (in other languages))
