[Trigger] Need Help with Pathing Detection

[Cronos]

I am using a simple GUI projectile system for my map, and the problem I am running into is an error I keep getting for using a custom script that detects terrain pathability. I am not very good at triggers so I checked out some maps for reference and decided to use a boolean that will check if a point is pathable.

The custom script goes like this: "set udg_Walkable = IsTerrainWalkable (GetLocationX(udg_TempLoc02), GetLocationY(udg_TempLoc02))"

Walkable is the boolean variable, and TempLoc01 and TempLoc02 are point variables (TempLoc02 is for where the projectile will land next). However, I keep getting an error that says expected a name. What am I doing wrong, am I missing something?

Wrong function name

native IsTerrainPathable takes real x, real y, pathingtype t returns boolean

This could be usefull (part with checking pathing) or you can use Jass system found is Jass resources =)

However, in GUI you should use:

• Set Walkable = (Terrain pathing at TempLoc02 of type Walk able is off)

• Custom script: set udg_Walkable = IsTerrainPathable(GetLocationX(udg_TempLoc02), GetLocationY(udg_TempLoc02), PATHING_TYPE_WALKABILITY)

Types of terrain pathing if you want to use custom scripts or jass:

Any - PATHING_TYPE_ANY
Walk able - PATHING_TYPE_WALKABILITY
Fly able - PATHING_TYPE_FLYABILITY
Build able - PATHING_TYPE_BUILDABILITY
Pathing for peons - PATHING_TYPE_PEONHARVESTPATHING
On bligth - PATHING_TYPE_BLIGHTPATHING
Float able - PATHING_TYPE_FLOATABILITY
Water pathing - PATHING_TYPE_AMPHIBIOUSPATHING

But if i remember correctly it the returns the opposite of what it should (true if the pathing type is off and false if the pathing is one).

So it should be that :

set udg_Walkable = not IsTerrainPathable(GetLocationX(udg_TempLoc02), GetLocationY(udg_TempLoc02), PATHING_TYPE_WALKABILITY)
