	This is a topic about random things that you can do in C++ that are not obvious. How do I... Iterate over all objects that are relevant to me? Code for( TObjectIterator<UObject> O; O; ++O ) { }//Iterate over all UObjects. How do I... Convert a "FString" into const TCHAR? (useful for logging) Code FString F= FString::Printf(TEXT("%s"),TEXT("nedm")); GLog->LogF(TEXT("%s"),F); //the "" operator on FString converts your FString into a const TCHAR. How do I... Convert a const TCHAR to FString? Code const TCHAR Str = TEXT("nedm"); FString F= FString::Printf(TEXT("%s"),Str); How do I... Load an arbitrary class? Code (UTexture )StaticLoadObject(UTexture::StaticClass(), NULL,TEXT("Engine.S_Actor"), NULL,LOAD_NoWarn \| LOAD_Quiet,NULL);//Load Engine.S_Actor texture. ...More to come.

Code const TCHAR *Str = TEXT("nedm"); FString F= FString::Printf(TEXT("%s"),Str); Why not just use FString constructor here? Code FString F = Str; FString F2(Str); auto &&F3 = FString(Str); Pre-227 version does not have such a ctor?

	That works too, but printf is generally more useful (albeit slower)

	You can also use the LoadObject<T>() template instead of using StaticLoadObject() directly. This equivalent for for the above example would be: Code LoadObject<UTexture>( NULL, TEXT("Engine.S_Actor"), NULL, LOAD_NoWarn \| LOAD_Quiet, NULL );

	Assuming this is a good post to post a couple of "How do I" questions. 1) Is there some "tick()" equivilent function that loops constantly in-game when coding natively? 2) Similar to question 1, but is there a native looping function that is called in-editor to update that environment? Or is that something that happens in the Render.Render class? Thanks.
