Sorry i am a beginner and don't know much of the classes.

i was thinking more of structs with dynamic array.

As you can see i need to create a bullet everytime i press fire button, this will create a new structs with the object id and life(counter) in it.Then i would decrement its life by 1 and if its equall to 0 delete the element of which the life is 0.

Sounds simple ......... but i don't know how to do it.

Classes are basically a struct. All struct, unions and classes in c++ can now have methods (or functions) that are specific to that class. That means you can have the same function name "update()" in as many classes as you like.

Before I wrote that class I added to the docs this:



And then I wrote my code. Now and then I'll do it that way.

Once you start understanding classes they are so useful mainly because of the constructors and destructors. The destructor can be used in GDK to cleanup and objects of allocated memory used by that class. For example in the CameraControl class, I've initialises the bullet class and the destructor frees the memory. You don't need to worry about the destructor because it is called when the class goes out of scope (ie when the program exits).

Well ok , i have grasped the vectors and now what i need to do is make a struct with three ints . Then i want to make a vector of it.

The vector may be streched or enlarged if the user presses fire then if one of the int counter reaches 0 , delete that element.

Oh and plz rem the code and a tutorial will be great for me and all the users seeing it.

You're almost there. Instead of using:

struct bullet p;

just use:

bullet p;

I'd advise for now to use the basic arrays:

bullet p[10]; // to store 10 bullets

To position the bullet the same as the player:

dbPositionObject(p[loop],dbObjectPositionX(obj),dbObjectPositionY(obj),dbPositionObjectZ(obj));

Then set the angles using this:

dbSetObjectToObjectOrientation(p[loop],obj);

(hopefully no typos there...)

yeah that's what i used to do.

But lets imagine this , my game has 100 guns and all of them fire if they see me.EVEN if half of them see me they fire a bullet every 10 frames. So this creates about ,i don't know , maybe 10000 bullets.

SO if i loop through all of them its ok i use for(int x=0,x<=10000,x++)

But if only one of them sees me , we then have about 50 bullets. And my compiler is just gonna go/loop for 10000 objects just to see if they are active or inactive.I need an alternative, any ideas.

By the way , you are still on the forum WLGfx, you must be a moderator by now.(but who am i to judge?)

If you mind the last two lines , ignore them.

I posted these for anyone who needs help with the <list> library. Take a look and see if they help. I think I might have posted another.
