Today I learned - Share your newly found knowledge! - Slice - 15.07.2012
Yes, just like reddit.
Simple. If you learned something new related to SA-MP scripting, share it here!
Please:
- Explain what it is you learned, don't just say you learned something. <----
- Try keeping it concise.
- Don't post stupid pictures or otherwise annoying, non-related stuff.
- Don't link to or quote posts then say you learned that.

TIL a little trick to extend the amount of statements executed in ternary statements.
Never thought about using the ',' operator this way. Group of statements must be enclosed in brackets. It's a neat little trick that might create some interesting constructs:
pawn Code:
main () {
new bool:cond = true;
cond ? (print("T - First"), print("T - Second")) : (print("F - First"), print("F - Second"));
print("SWITCHING TRUTH");
cond = false;
cond ? (print("T - First"), print("T - Second")) : (print("F - First"), print("F - Second"));
}

Today I learned that publics like OnPlayerText (in a filterscript) are still intact while the gamemode is restarting so you can, for example, actually still chat using Send(Player/Client)Message(ToAll)!
