Modding Help Call Function in Player Script

I've written my own Player Script by patching the player.config.

Is it possible to call a Function in this script by an Object?

I already tried to use this functions, but it didn't work:
"world.callScriptedEntity" and "world.sendEntityMessage" (of cause by using the Message-Handler)

At the moment I transmit signals by using global variables, but that's quite inefficent and annoying.

 

Ok, so is there at least any way that is a bit more... elegant?

 

A simple planetside teleporter.
I set the new player position in the player script and want to transmit the coordinates (where to teleport) from an object to the player.

 

Have you considered a status effect script? Just shooting from the hip here.

 

I already tried that. It's as slow as working with global variables.
I just don't know why no function is added to be able to call functions in player scripts...
