[JASS] Cliffs and units

[Maximash]

Hey, i was wondering.. is there a way,without using alot of regions, to make it so when a unit touches a cliff it is killed?(This is for a bullet... i dont want the bullets to go through walls)

 

[Mechanical Man]

If you want to do bullet system, then do the following:

Before units shoots, check point for point (with some spacing of course) to where the terrain is passable (with a dummy unit for example) and no units/doodads in proximity. When you find that point, order unit to attack ground/use spell (or whatever) to that point.

 

[wyrmlord]

There is a function to get the cliff height. You could just check for an increase in cliff height from where the bullet currently is and where it will be moved to.

The function is GetTerrainCliffLevel

Wait.. would this script work? (if you cba to read that, then all i need you to see is- set udg_BulletOffset = PolarProjectionBJ(GetNearestPathableLoc(GetUnitLoc (udg_Bullet)), 50.00, GetUnitFacing(udg_Bullet)) that works right?

And @Wrym Lord,how do i find out the TerrainCliffLevel that a particular unit is on?

 

[wyrmlord]

GetTerrainCliffLevel takes 2 parameters, an x position and a y position. You just pass the unit's x/y coordinates and that should work.

 

[Maximash]

so...GetTerrainCliffLevel (GetUnitX(udg_bullet)), (GetUnitY(udg_Bullet))
not sure about the commands to get a units X and Y,
not amazing at JASS
EDIT:Nevermind found a way, so will this work?
endif
call GetTerrainCliffLevel Location(GetLocationX(GetUnitLoc(udg_Bullet)), GetLocationY(GetUnitLoc(udg_Bullet)>= 1))

 

[wyrmlord]

so...GetTerrainCliffLevel (GetUnitX(udg_bullet)), (GetUnitY(udg_Bullet))

That way would work, only you typed it a bit wrong, it should be:

GetTerrainCliffLevel(GetUnitX(udg_bullet), GetUnitY(udg_Bullet))

 

[Maximash]

ahhh i see thanks for the help so
endif
GetTerrainCliffLevel(GetUnitX(udg_bullet), GetUnitY(udg_Bullet)>=1)

will stop the trigger if the cliff height is greaterthan or equal to 1?

 

[wyrmlord]

ahhh i see thanks for the help so
endif
GetTerrainCliffLevel(GetUnitX(udg_bullet), GetUnitY(udg_Bullet))>=1

will stop the trigger if the cliff height is greaterthan or equal to 1?

Fixed. You were putting the >= 1 inside the function call, which would have made the second parameter boolean instead of real. This would stop it if the cliff level was greater than 1, but not if it was 1 higher than the current level of the unit. To do this, you'd do the same thing, but first do it for the unit and then for the location the bullet would be moved to. If the second location had a higher cliff level, destroy the bullet.

OKi doki thanks alot wyrmlord
