bool IsVisible(Actor other, bool allaround[, LookExParams params])


Checks if the specified actor is visible to the calling Actor. Checks similarly to A_Look's visual checking but does not modify the Actor in any way.


  • other - The actor to check sight of.
  • allaround - If true and params is not specified, look all around the Actor similar to the LOOKALLAROUND flag.
  • params - null by default. Allows parameters similar to A_LookEx to be passed e.g. minimum distance, fov, etc.

Return value

Returns true if the other actor is visible.
