Description

Description:
Checks if one position is visible from another position and how much. The results can be affected by getTerrainGrid value, especially if position is near the ground. Particle effects such as smoke can also affect the results.
Groups:
Uncategorised

Syntax

Syntax:
[ignore, LOD, ignore2] checkVisibility [beg, end]
Parameters:
[ignore, LOD, ignore2]: Array
ignore: Object - object to exclude from calculations
LOD: String - level of details to use. Possible values are: "FIRE", "VIEW", "GEOM", "IFIRE"
ignore2 (Optional): Object - second object to exclude from calculations (Since Arma 3 v1.61.136673)
[beg, end]: Array
beg: Array - start position in format PositionASL
end: Array - end position in format PositionASL
Return Value:
Number - how much end position is visible to start position in range 0..1, where 1 is fully visible.

Examples

Example 1:
_cansee = [objNull, "VIEW"] checkVisibility [eyePos player, eyePos unit1];

Particles that have blockAIVisibility set to 1 will influence the result, but will not make checkVisibility return 0. Instead an extremly small number will be returned.
Distance, fog, overcast, rain and nighttime have no effect on the result.
