LineOfSightObject(object, object)

Is there a line of sight between two objects.

int LineOfSightObject(
    object oSource,
    object oTarget
);

Parameters

oSource

Source object

oTarget

Target object

Description

Returns whether or not there is a direct line of sight between the two objects. (Not blocked by any geometry).

PLEASE NOTE: This is an expensive function and may degrade performance if used frequently.

Remarks

With this function came a fix to GetFirstObjectInShape/GetNextObjectInShape, and makes sure fireballs do not go through walls or doors.

This is hardly ever needed practically - for spell scripts, it is not required unless an area-of-effect spell doesn't use GetFirst/NextObjectInShape, because the game already has internal restraints on Line-Of-Sight checks for single target or ground targeted spells.

Note that LOS is done at a Z = Ground Height + 1.0. NWN LOS is...pretty wacky (given it's a 2.5D game, this means something "flying up high" could be invisible if they're standing behind a small rock still, and that Dragons who are huge could be hidden by a small wall).

Example

//Can I see bob?
void main()
{
object oTarget=GetObjectByTag("bob");
 
int bCanISee=LineOfSightObject(OBJECT_SELF, oTarget);
}
