[Solved] Some quick questionz..

[GreeN!X]

Hey guys, I have 2 Pretty simple questions:

1.) Is it possible to check if an area is Not walkable, Can't be built on or If it's walkable?

2.) How do you people calculate the distance or measure or whatever in warcraft? I heard that the Small grid in the editor is 32, the medium grid is 128 and the big ones are 512.. I'm try to fit a special effect with the AoE of a spell.. :V

Answers are appreciated.. :3

1) Environment - Terrain at Loc of Pathability TYPEHERE Equal to true
But i guess you can use the same method as i use here : http://www.hiveworkshop.com/forums/spells-569/knockback-v1-8-v1-2-a-223634/?prev=status=a&u=Almia

2)Distance? We just use this for coordinates:
SquareRoot(( x2 - x ) * (x2 - x) + ( y2 - y ) * (y2 - y))
or you can use Math - Distance Between Loc1 and Loc 2

That is correct.

You can scale effects by creating a dummy unit, creating an effect on the dummy and scaling the dummy.

@Almia, you could improve the collision/movement method in your knockback, as now in tight spaces units have awkward movement

@Maker
yeah right. I might match it with its vJASS complement.

If I would use that, would it consider doodads? like pathing blockers?

^ I don't think it would.

No, it won't.

Another method is to move an item there, and check the item's coordinates.

Items can collide with other item, so you need to hide nearby items first.

 

[Almia]

^ Never thought of that.
I always use EnumDest and EnumUnits and IsTerrainWalkable combined to recognize pathing.

Alright, I have solve the pathing part.. thanks to the three of you who helped.. Gave you all a gift.. (and by gift, I mean REP :3)

@Almia : spreadin' first..
