eventHandler for player UI commands? e.g player changes an AI unit colour?

[bendy303 4]

Hi...

I keep losing the team colours of my AI units after they go unconcious....

I thought if I can add an eventHandler to monitor player command input, I can store the colour to a variable, then recall it after revive.

This link here is overwhelming:

help appreciated

cheers

Hi, Bendy,
handling such system through UIEH would be really hard. Fortunately we have also user eventhandlers that can do all sorts of things.
I prepared a quick example code that should be able to do what you need. But multiplayer scripting is not my cup of tea if you understand. Maybe you would also need to add functionality that would handle respawning, adding units to your group and so on. I hope that this code could help you at least a little bit. 🙂

Spoiler

/*
function that restores assigned team color when unit gets unconcious, it is also an example how to handle actions from command menu with eventhandlers
Might slightly affect FPS, because it's checked every time unit changes animation. if Bohemia would add unconcious eventhandler, that would be great
Also i'm not sure if addUserActionEventHandler is persistent or needs to be added every time player respawns-check yourself
