Title: ABL scripting error
Post by: Drewbs on August 22, 2018, 01:55:19 pm

I am encountering another syntax error for IsWithinArea. I have:
      if (IsWithinArea(VongL1a, -6976.0, -320.0, 0.0, 50.0) : true) then

The ABL library has:
IsWithinArea(UnitID, position Point, real Radius) : boolean;
      // UnitID(from GetUnitMates(SquadID,Array); , 3-point array or worldposition with xyz, range in meters

What am I doing wrong?

I'm new to this forum and haven't used the ABL scripts yet, but  I have some general programming knowledge and any interpreter woud read your current line as this:

Code: [Select]

IsWithinArea(VongL1a, -6976.0, -320.0, 0.0, 50.0) : true
IsWithinArea(UnitID, position Point, real Radius) : boolean
where the variables are read like this:

Code: [Select]

UnitID = VongL1a
position Point (expects array) = -6976,0
real Radius = -320.0because of the way the commas are used

you could try something like:

Code: [Select]

IsWithinArea(VongL1a, (-6976.0, -320.0, 0.0), 50.0) : true
either way, the function expects an array (however the syntax for arrays is in this language) between the first and second comma within the parantheses

position type is the user data type (array (3) in abl script.

It has integerl values:
x (x coord),
y,
z (usually 0);

declaration:
Position aPoint;

assign data:
aPoint[0] = 6293;
aPoint[1] = 6464;
aPoint[2] = 0;

Pass the variable to the function:
IsWithinArea(VongL1a, aPoint, 50.0)
