[JASS] Group Issue

[Chaosy]

I am currently using the following function:

        function Build(player p, integer id)
        {
            rect toBuild = gg_rct_Region_000;
            real x, y;
            location l;
            group g;
            while(true)
            {
                x = GetRandomReal(GetRectMinX(toBuild), GetRectMaxX(toBuild));
                y = GetRandomReal(GetRectMinY(toBuild), GetRectMaxY(toBuild));
                l = Location(x, y);
                BJDebugMsg(R2S(x)+ " " + R2S(y) + " " + I2S(id));
                g = GetUnitsInRangeOfLocAll(100, l);
                if(FirstOfGroup(g) != null)
                {
                    IssueBuildOrderById(gg_unit_opeo_0004, id, x, y);
                    BJDebugMsg("no null");
                    break;
                }
                DestroyGroup(g);
                RemoveLocation(l);
            }
        }

This is not finished which is why I don't use the p variable yet etc, but that's not the issue.

The code is supposed to order a peon to build in a specific region but make sure there is nothing blocking the randomized location.

The debug messages show correct values so they are not the issue.

I placed the peon inside the region and it build properly, but when I moved the region it suddenly stopped working, it does exit the loop.

It does not pass the condition, despite it being impossible for it to fail:

Fixed up the thread, since I debugged a bit so the info changed.

 

[Maker]

Did you move the region with triggers or in WE? Does FirstOfGroup detect the peon?

 

[Chaosy]

I moved it in the WE not with code.

And apparently it does detect something but as you see in the image that should be not able to happen.

edit:
Oh shit, I fucked up. It should be == not !=
