ai_script_conditions is a point entity available in all Source games except Left 4 Dead series. It allows a mapper to define a list of conditions relating to the player, an NPC, and an optional target, that trigger events when the conditions are fulfilled.

Fired only once, automatically, when the condition is first fulfilled, then disables itself. Use Enable inputs to recheck conditions.

An example of its use is on d2_coast_03. When Odessa holds out the rocket launcher for Gordon to grab, an ai_script_conditions is used to tell how close the player is to Odessa. When the player is within a very small range, Odessa drops the weapon. 99% percent of the time, the player will be close enough that they will then automatically pick up the weapon_rpg.

Note:Distances do account for crouching. A proximity condition that is fulfilled while not crouching might be unfulfilled while crouching.

Note:notarget will affect LOS conditions.

Bug:This entity is hardcoded to be based on the SP player, causing a crash when enabled in multiplayer games.  [todo tested in?]
