Client Command by Trigger proximity

From Valve Developer Community

Sometimes, either for testing or gameplay purposes, you may need the client (player(s) on your map) to execute a console command. This tutorial explains how to make a console command which executes on the start of every round in CS:S and makes a single CT activate his flashlight. If you want things to be used multiple times, read at the end of this tutorial what you need to do.

Entity requirements

• Player spawn. e.g. info_player_start, info_player_counterterrorist, info_player_terrorist, etc.
• Trigger_proximity
• Point_clientcommand
• Logic_auto
• Information about client commands: Command, Console Command List, and Impulse

[edit] Tutorial Create a player spawn, if you haven't already done so. [edit] Setting up the point_clientcommand Create a point_clientcommand and name it clientcommand.  Note: It doesn't matter where you put it, but a sensible place might be near the player spawn so you don't lose it. [edit] Setting up the trigger_proximity Create a box near the player spawn. e.g. in or underneath the player spawn. Tie (Ctrl+T) this box to a trigger_proximity entity. With these properties: Class: Trigger_proximity Keyvalues Comments Name triggerprox_1 Parent <empty> Origin (X Y Z) Leave untouched Start Disabled No Global Entity Name <empty> Filter Name <empty> Point to Measure From <empty> Radius to measure within 2 Make an output on the trigger_proximity box: My output Target entity Target input Parameter Delay Only once Comments OnStartTouch clientcommand Command impulse 100 0.20 signed Active the flashlight on Client's side [edit] Setting up the logic_auto Create a logic_auto with this output: My output Target entity Target input Parameter Delay Only once Comments OnMapSpawn triggerprox_* Disable <none> 5.00 signed De-activate the trigger triggerprox_1  Note: IMPORTANT! Don't forget the wildcard (*)! This will automatically disable ALL trigger_proximity-entities after 5 seconds, so none of the other players executes the command, if the trigger_proximity was not fired.

Multiple ...

Triggers

For more triggers, like described in this tutorial, copy the point_clientcommand and the trigger_proximity. Rename them both to make sure they are only related to each other. Now place them at more player spawns.

etc.
Leave the logic_auto as it is, since it will automatically search for more triggerprox_ prefixes because of the wildcard (*).The clientcommand is still the same, because it will just execute the Client Command and does nothing else.

Commands

For multiple commands at a time, add more outputs to the trigger_proximity-entity:

		My output	Target entity	Target input	Parameter	Delay	Only once	Comments
		OnUser1	clientcommand	Command	impulse 100	0.20	signed	Active the flashlight on Client's side
		OnUser1	clientcommand	Command	jpeg	0.00	signed	Create a screenshot on Client's side

 Note: Notice that the target entity names are still the same!

Tips for commands

For this tutorial, a flashlight (impulse 100) was used as a command. There are many others that come in handy. Feel free to add your own suggestions (including the Console Command, circumstances):

 Note: Any command that has spaces(e.g. ent_fire <ent_name> <message>) requires double quotes. This will crash Hammer next time you load the level, as Hammer uses double quotes to separate parts of messages. Currently the only way around this(to my knowledge) is to use double quotes when compiling, which will work fine, but when exiting Hammer change the double quotes to single quotes(then save). Next time you load the map, remember to change them back to double quotes.
