func_minefield

func_minefield is a brush entity available in Black Mesa. This entity is trigger volume that also creates mines. The mines can be spawned on world geometry, func_detail and displacement, they ignore brush entities and point entities. The mines can be spawned randomly or depending on the uniform displacement properties. Spawned mines are not attached to trigger volume, each mine is indepeding env_mine entity. The trigger volume can be used as trigger_multiple.

Represented by class CFuncMineField.

Note:Mines can be spawned incorrectly on displacement surface, showing their barrels.

Bug:This entity can sometimes spawn multiple mines inside each other.

Keyvalues

Mine Count (minecount) <integer>

The amount of mines to spawn.

Uniform Random Spread X (ranx) <float>

Uniform displacement of mines along this axis. Works only if Uniform displacement flag is checked.

Uniform Random Spread Y (rany) <float>

Uniform displacement of mines along this axis. Works only if Uniform displacement flag is checked.

Inputs

MineDetonated <targetname> !FGD

Fires when a mine explodes. This input does nothing itself. Used for debugging. If a mine have a name - this input will use the mine name as parameter.

BaseTrigger

Toggle Toggles this trigger between enabled and disabled states. Enable Enable trigger Disable Disable trigger TouchTest  (in all games since ) Triggers either the OnTouching or OnNotTouching outputs for whether anything is touching this entity. Bug:Sleeping prop_physics will never fire "OnTouching". Also applies to entities using prop_physics as base.  (tested in: ) StartTouch  (in all games since ) !FGD Behave as if the !caller entity had just entered the trigger volume. Accepts non-physical entities. EndTouch  (in all games since ) !FGD Behave as if !caller had just exited the trigger volume. DisableAndEndTouch  (only in ) Disables this trigger and calls EndTouch on all currently-touching entities.

Outputs

BaseTrigger

Bug:Spamming crouch jumps in a trigger can randomly fire OnStartTouch/OnEndTouch. Confirm:Is it a Multiplayer issue only?   [todo tested in ?] OnStartTouch !activator = entity that caused this output !caller = same as !self Fired when a valid entity starts touching this trigger. OnStartTouchAll !activator = entity that caused this output !caller = same as !self Fired when a valid entity starts touching this trigger, and no other entities are touching it. If there are any other entities touching the trigger when a new one begins to touch, only OnStartTouch will fire. OnEndTouch !activator = entity that caused this output !caller = same as !self Fired when a valid entity stops touching this trigger. Note:Will also fire for entities touching it when trigger is disabled via Disable input Warning:This includes entities which are deleted while inside the trigger. In this case !activator will be invalid. Warning:OnEndTouch can fire before OnStartTouch under certain circumstances[How?] where both are fired on the same tick and each have the same delay. Fix:Add a slight delay to OnEndTouch. OnEndTouchAll !activator = entity that caused this output !caller = same as !self Fired when all valid entities stop touching this trigger. OnTouching  (in all games since ) !activator = !caller = !self Fired if something is currently touching this trigger when TouchTest is fired. OnNotTouching  (in all games since ) !activator = !caller = !self Fired if nothing is currently touching this trigger when TouchTest is fired.
