From Garry's Mod
Returns whether the target/given entity is visible from the this entity.
This is meant to be used only with NPCs.
Differences from a simple trace include:
- If target has FL_NOTARGET, returns false
- If ai_ignoreplayers is turned on and target is a player, returns false
- Reacts to ai_LOS_mode:
- If 1, does a simple trace with COLLISION_GROUP_NONE and MASK_BLOCKLOS
- If not, does a trace with MASK_BLOCKLOS_AND_NPCS ( - CONTENTS_BLOCKLOS is target is player ) and a custom LOS filter ( CTraceFilterLOS )
- Returns true if hits a vehicle the target is driving
Entity to check for visibility to.
If the entities can see each other.
