Is there some method to perform a wait action in lua that isn't system dependent? If not what's the best way to do so? Also, is there a way to use golden hammers in lua without crashing rom? Thanks in advance.

Yeh the kind of thing I want to do is similar to the fusion addon in a sense of repeating commands. It's an expansion of an existng addon (simple repair hammer), but I am making some xml frames for some customisation (like what dura to look for, etc.). I wanted the addon to use therefore only 1 command to execute from the onmouseclick event (instead of having a macro script in game). It may be totally unneccessary but I want to learn some addon development for rom. I alredy expanded this code to a working state except for using golden repair hammers. When it hits pickupequipmentitem(#) rom crashes, but idoesn't do it for simple repair hammers. But yeh basically I need to loop simmilar to fusion but I have no computer at the moment so I Can't look there for ideas and wanted to know if anyone knew offhand.
