Draw is a handle that works, but probably not in the context you're using it in. I assume you're using this script in a Script entity. In this context, I don't believe there is a functioning Draw handle. (I could be wrong, but Bromvlieg should be able to confirm or deny this.)

What I do know is, in the context of addons (Scripts/Addons/*/cl_init.bs) you can make custom HUD elements with the Draw handle.

For example, this should work as an addon: (try it in the script entity too, though I'm not 100% certain whether it works)

I was using it in the Script entity, sorry for not specifying it.

When I ran your script I saw no text on screen so I added a line to print the width


It kept printing to the console, I then changed it to heigth and it was printing both, so I know that now there are 3 "hooks registered", 1st shows me nothing, 2nd shows me nothing and prints width and 3rd shows nothing and prints height.

What is "OnHUDDraw" and what other identificators/strings can I replace it with?
Is it possible to unregister/delete hook after it does what it does just once?
Am I able to pass the handles without calling RegisterHook() ?

I suppose drawing only works properly in addons then. Are you stopping/starting the script from editor? Not sure why it keeps the registered hooks in memory then, that's probably a bug.

Here's a list of hooks that are currently being called: (I haven't tested them myself though, also I'm pretty sure not all of these will work in Script entity, but rather in Addons)

• OnInitialize()
  
• OnMapStart()
  
• OnMapEnd()
  
• OnRoundStart()
  
• OnRoundEnd()
  
• OnUpdate()
  
• OnPlayerConnect(int client_index, string client_name, uint64 client_steamid, string client_sentpassword)
  
• OnPlayerDisconnect(PlayerHandle player)
  
• OnPlayerDeath(PlayerHandle player)
  
• OnPlayerSpawn(PlayerHandle player)
  
• OnPlayerInit(PlayerHandle player)
  
• OnHUDDraw(DrawHandle draw)
  
• OnChat(int client_index, string message)

I'll also link this thread to Bromvlieg, he'll be able to give you more info.

I am doing everything within the editor, starting the script with a trigger.

Thank you, I will try messing around in the Addons folder now.
