Hi there, I'm trying to implement my UI while also fiddling with GetLocalPlayer(), I wonder if this method of doing it causes any desync. Is it unnecessary to do it like that, can I just use "BlzFrameSetTexture(backdrop, s, 0, true)" in the GetLocalPlayer() block? How do I test if any...

Inspired by Chopinski's Relativistic Missile System way of processing missiles, I've come up with an idea of mimicking OS's process scheduling inside Lua's runtime for the purpose of eliminating "processing" lag by sacrificing the fact that the code will always execute immediately upon call. At...

1. What are the constraints and best practice for FourCC allocation? (except for H*** for heroes) 2. Is it possible to place same ability on different UI button positions depending on unit type? (non-hero) 3. Does Leak matters in Reforged, given sufficient memory? (In other words, will incur...

Disclaimer: This is not something you would ever encounter under normal circumstances. TLDR: At very high GC pressure processes' memory will grow. If the GC catches up, the memory will not be released to OS. I'm currently attempting to debug a memory leak in a big trigger-heavy map I'm porting...

Common knowledge has it Jass strings leak!!!1 and are bad!!!1 Let's benchmark by generating A TON of strings. Test code & setup The code below takes your chat message, like "-10" and generates ONE 10-char long string (1=10/10). That's equivalent to generating 10 distinct unique strings in Jass...

A few threads here have made me curious: "...then I found the automatic JASS to LUA converter." - Macadamia found by mistake that WorldEdit can transpile all Jass code to Lua. Nobody knows how exactly "Lua, embedded jass" - Tasyen found out, that Lua maps can have Jass code, automatically...

Hello, First off I realize that both ceres and cerrie have more-or-less been abandoned. I didn't want to let a little abandonware come between me and excellent tooling so I've given a shot at using them. Honestly all-in-all my experience has been excellent. (Regardless of current project...
