Crash while push back objects - RyDeR` - 16.08.2010

Hi,

this is the way I let create my objects in C++:

Код:

static cell AMX_NATIVE_CALL Core_CreateStreamedObject(AMX * amx, cell * params)
{
	Object object;
	object.objectID = params[1];
	object.x = amx_ctof(params[2]);
	object.y = amx_ctof(params[3]);
	object.z = amx_ctof(params[4]);
	object.rx = amx_ctof(params[5]);
	object.ry = amx_ctof(params[6]);
	object.rz = amx_ctof(params[7]);
	object.distance = amx_ctof(params[8]);
	objects.push_back(object);
	return 0;
}

When I'm over 250.000 objects samp-server.exe crashes while creating. Why?
When I delete "objects.push_back(object);" it doesn't crash and it creates as much as you want but you can't see them ingame.

Well,you can't push_back the struct.Try to use iterator and get last element of vector.

Re: Crash while push back objects - Zeex - 16.08.2010

If "objects" is a vector, try the following

Код:

// call when plugin gets loaded
objects.reserve(n);

where n is the maximum number of objects you're gonna create. This will allocate enough space for n elements inside the vector and it won't grow and re-allocate memory while you're adding the objects (should also increase performance btw). If it still fails, you may also try using a static array instead of container.

Then he must to define vector like <str> or even my bad?

Answer: He wants to improve his streamer into the plugin and also to create unlimited.

pliva_sb:
Thanks for your responses man but can you maybe give a little bit more info about what you mean?

******:
I totally agree but it's always nice to have something you made yourself for own usage in my opnion.

Zeex:
Thanks, worked but still can't go unlimited - When I reserve more than 1.000.000 samp-server.exe even don't start.
I have no idea how to fix this.

My point was to get this streamer streaming unlimited objects. First I worked with array sizes which was very bad because I couldn't go over 700.000. I asked Incognito in PM he told me to do in this way so I did. My streamer works perfect just when I create more then 'x' amount it crashes.

I hope someone can give me a solving answer to this problem, please ask if you need more info about this to solve.
