RequestID()

Yes, we need this!

Why?

Regulary I'm creating event-based code, usually gadget-related. Since I need my own event id's to have it al working I need to keep track of free ID numbers. Usually all my own events start with 1337, then followed by some obscure 0666 number orso. :P

But it would be perfect if there was this RequestID() function that simply keeps track of a list of used EventID's, the BRL ones and even your own ones. So, the only thing you'd have to do when creating an event id is doing:
Global EVENT_COLORCHANGED:int=RequestID()
Global EVENT_COLORCHANGING:int=RequestID()
Global EVENT_BUTTONPRESSED:int=RequestID()
Global EVENT_PALETTECHANGED:int=RequestID()
etc.

Kinda like enum except that you don't need to know which ID's are in use already.

This list of IDs should prolly be an object with a list inside, so this RequestID() function would know where to look for used eventIDs.

A function like this would save me from searching through all my files to check if I don't overwrite some ID (let alone BRL introducing a new ID on a position *I* was already using for my own stuff!). Also, it's portable across users who have their own list!

I generally use an MD5 hash of millisecs + some random thingie.

Yep, and asked for the same some time ago.
AllocHoodId works with a global array of 256 numbers farming out the next number each time.
You could do the same making the first number 'safe'
i.e. > 32769 but you can't guarantee they won't be used again in the future.
or 0-255 which are not currently used.

Even when using a safe number, you'd still have to check on your own ID's being overwritten, and your code would still not be truly portable.

True your code won't be portable but you wouldn't overwrite if you keep the safe numbers in an array plus a pointer to the next one to use. Alternatively, use a number like Indie suggests.
