Creating unit out of bounds / unwalkable terrain

[sethmachine]

Hi,

So apparently if a unit is created at location which is outside the map bounds, it crashes?

Or is the proper term that the thread where it came from crashes? I've got a trigger that picks a random point around a unit and creates a unit at the point (random point on a circle). Never once did my game crash...I would have expected at some point a unit would be attempted to be created out of bounds.

So if it's being done its own thread, is it even necessary to check world bounds on the point? If it crashes the thread, then it crashes. Or would it leak a unit reference?

I've got WorldBounds library though, so I suppose I should add that in as an additional check when generating a random location?

Second part of the question: What about creating a unit on terrain that isn't walkable, e.g. a land unit being spawned on a location in the water, or in a boundary area (that's still inside the world bounds).

What happens in that case? Does the unit instance still exist? Does it crash the thread, or will code continue to execute?

local unit u = CreateUnitAtLoc('Hpal', ..., waterLoc, ...)
//what happens now?  what does u point to? 
//will the following code run properly?
call SetHeroLevel(u, 100, true) 
//will I see the unit level up at the waterLoc?
call SetUnitLoc(u, myLoc) 
//will the unit appear suddenly at this loc?

If you have WorldBounds library you don't need to worry about first case.In case you wondering, I heard when a unit outside bounds ordered to do something, it crashes game(fatal error).Not sure if it is still exist.

Second case, everything will be fine.

What happens in the second case, though? And how does putting in WorldBounds fix everything automatically? I'm using Nestharus' worldbounds, as shown below.

            set maxY=R2I(GetRectMaxY(world))
            set minX=R2I(GetRectMinX(world))
            set minY=R2I(GetRectMinY(world))
            set centerX=R2I((maxX+minX)/2)
            set centerY=R2I((minY+maxY)/2)
            set worldRegion=CreateRegion()
            call RegionAddRect(worldRegion,world)
        endmethod
    endmodule
    struct WorldBounds extends array

    endstruct
endlibrary

The second case, units will be created perfectly. I've tried making water in start locs. xD

They won't move tho if Land walkers.

If they are land based units, and they are created in a location which is

1. water

What happens? Do they get spawned? ???

2. boundary (not out of bounds though, just the black boundary terrain).

Same thing--what happens???

Yes. I said that in my last post. ;_;

2. I believe yes. You can test though.

 

[sethmachine]

Where do they get spawned though ???

Can't put a unit on water or a boundary. Never seen it in game happen :[

 

[Vinz]

Hm.. perhaps it is only StartLocation that does that? I don't know, MoveUnit, SetUnitX/Y? Perhaps you were talking about training? Sorry, can't be of help.

Talking about "CreateUnitAtLoc"

Still would like an exact answer as to what happens...
