Future ZScript needs to allow NON-CONSTANT globals to be set

Agreed. Global objects would be ideal. The only way to do this at present, is through cheating via the global active script, which is absolutely horrible, and evil, and...you know.

@ Anarchy_Balsac It would be useful if you posted the exact error that you saw, and the related code. I have never seen an error like that, except when trying to declare a complex object type at a global scope (i.e. ffc, item, npc, weapon).

Before we muck with making all those types possible as global declarations, we need to expand the size of the array that holds the ZASM gd registers, and modify the bytecode to reflect that change. Placing them at the end of a much larger array would work, but you'd need to keep the first 256 where they are, and map the rest elsewhere, for the sake of compatibility.

I was so furious when I posted that I didn't even think about it. Too late now though.

No chance of recompiling it the way that you had it before?

Here's a little bonus... How to make a global complex object, of sorts.

You can do this with weapons, and ffcs. It'd also work with npcs, but I'm not certain if there's a point to that.
