[JASS] SetRectTerrainType

[Element of Water]

This isn't much, but I felt wc3 was lacking this function. It basically changes the terrain inside a rect to whatever you want. Here's the code:

function SetRectTerrainType takes rect r, integer terrainType, integer variation returns nothing
    local real minx = GetRectMinX(r)
    local real miny = GetRectMinY(r)
    local real maxx = GetRectMaxX(r)
    local real maxy = GetRectMaxY(r)
    local real x = minx
    local real y = miny
    loop
        exitwhen y >= maxy
        loop
            exitwhen x >= maxx
            call SetTerrainType(x, y, terrainType, variation, 1, 1)
            set x = x + 128.0
        endloop
        set y = y + 128.0
        set x = minx
    endloop
endfunction

I don't know why, but this function doesn't work after TriggerSleepAction is called, but I'm sure there are ways round that, such as using a timer, though I haven't tested any.

Why 130 instead of 128 ?

Sorry I didn't know what the correct value was, but 130 seemed close enough. I'll edit it, though it wouldn't make any difference in all but the largest rects...

EDIT: fixed.

That almost definitely has to do with the context you were testing it in.

I tested it by doing:

call SetRectTerrainType(gg_rct_test1, 'Lgrs', -1)
call SetRectTerrainType(gg_rct_test2, 'Lgrs', -1)
call SetRectTerrainType(gg_rct_test3, 'Lgrs', -1)
call SetRectTerrainType(gg_rct_test4, 'Lgrs', -1)
call SetRectTerrainType(gg_rct_test5, 'Lgrs', -1)

and it all worked until I put call TriggerSleepAction(0.5) after every call, then it just worked in the first rect, but didn't do anything to the others...

would you please post the whole code you used for testing? There must be some reason why only the first rect gets converted.

 

[PurplePoot]

Was that inside a boolexpr or a timer callback?

Well, it was in the main menu for my project - Azeroth - Total War. It's not quite done but it has the SetRectTerrainType function working in it perfectly.
