![]() ![]() It is not automatically cleaned up after exitting it's scope, and must be manually checked constantly for deletion. It requires a Garbage Collector and is much slower to initialize. But the Heap is not as good for many things. You can create everything on the Heap, and have everything nullable. That doesn't mean you really need to use value types. In reference to stack memory it becomes impossible to set it to null, it's not a concept that makes sense in context to the stack. This means you cannot set it to reference another variable, nor can you null it, as it will always point to the same point in memory regardless of what you do. When an object is on the stack, it cannot be passed around, and will be destroyed upon exiting that bit of logic. Think stack trace for stack memory, it gets loaded and unloaded based on what part of the stack you are in. You are pretty spot on for the Memory types, Heap is handled by the Garbage Collector, and Stack is handled based on the program order. So Nullable types may not function(depends if Unity added it), however the Value vs. I know I'm showing C# MSDN references, however they both use the same underlying compiler. Reference types is not something that you can intrinsically know from the start, it can be a bit vague. Thanks you guys for giving me such detailed answers- I don't remember things if I don't use them. I have every intent on switching to C#, but the majority of my code is already written for this game and I see no point to switch yet. I'm using Javascript right now (not that that should matter). ![]() Is that some sort of variable attribute that I vaguely remember from Concepts Of Programming Languages? But that's why I'm here on the forums learning it again, right (I mainly pulled out REGEXs and context sensative languages for compiler building)? Don't tell me, I htink it is better if I run into the attic and dust of that book and give a few run throughs of the chapters.Įric5h5- are you sure they can't start off as null? I don't mean to question you since I have a great respect for you and your answers (as well as Dreamora), but I swear that sometimes I'll get null pointer exceptions on Vector3's I don't initialize. I'm a little bit fuzzy on my Concepts of Programming Languages, since we only studied it an never really applied it. I hate jumping through ropes just to do something other langauges can do in a single line (I also hate languages that don't have some built-in form of REGEX since they are so very useful). Click to expand.I should have been clearer- I hate it when languages don't allow you the exact syntax of var = null. ![]()
