If "keypressed

#1 Depending on what game mod you are working with, check game\scriptsAndAssets\client\scripts\default.bind.cs.

This script shows you how to create an action map and keybindings for calling methods you write.

#2 So i always have to use action maps for checkings keys or is it possible to ask it inside a function?

If i have to use action maps, i'm thinking about a good way for creating a "use" key to do many different actions like open doors, click a lightswitch, etc.

I would probably write a function "useAction" or something and bind that to the "e" key. In this function i would set a variable "usedActionKey" to 1 and change it back to 0 after few miliseconds.
So i could write my code like:

if(vectorDist(%obj.getPosition(), $playerPtr.getPosition()) < 5 && $usedActionKey)
{
  openDoor();
}

Would this be a good solution or are there any better "tricks"?

Thanks in advance!

#3 Sounds like you are off to a good start Kiyaku. If I can make one suggestion, I would create the binding and function call on the client side, and the "guts" of your functionality on the server side:

In a client script, like default.bind.cs

moveMap.bindCmd(keyboard, "e", "commandToServer('useAction', true);", "");

In a server script, like server\scripts\commands.cs

function serverCmduseAction(%client, %active)
{
       if(vectorDist(%obj.getPosition(), %client.player.getPosition()) < 5 && %active)
       {
             openDoor();
       }
}

The only issue I see is where you get the %obj. Other than that, sounds like a good start.

#4 I made a resource that casts a ray after pressing a button and then performs an action after that.

#5 Thanks a lot, i managed to finally finished the "use" and "trace" function and it works perfectly.

Though i didn't use the Server Commands yet as you stated, michael. I couldn't get it to work and i didn't check the multiplayer parts yet but will do that soon and try to rewrite it.
