[SOLVED] Repeating texture and Freeing memory help!

Hi Guys, I needed help with two questions. [1] In my game i am trying to create a floor terrain (using vertex buffer and creating a square with UV coords added on). Now before I had the floor at a small size, and it was textured with D3DXCreateTextureFromFileEx. This was fine as the texture resolution was 2048x2048 so it didnt appear stretched. But now I am wanting to increase the size of this terrain floor, therefore I have scaled the box by quite a huge factor! My problem is that the texture is now obviously appearing streatched! Instead is their a way for me to draw the same texture multiple times on the terrain without stretching it creating a seamless tile of grass(the texture im using)? One idea i had was to keep the original floor size(one without the scaleing done) and create a FOR loop to draw multiple squares for the floor and make it look like one big square! But i dont know how effective this would be compared to the first idea? Which one should I do, i would idearlly like to implement the first one(seamless tiles of texture) but only if it doesnt require much changing to existing code? [2] My second problem is to do with classes. I have a Sky class, in my main.cpp im calling it to render the skybox. Hence in the main.h i have an pointed object of the class: Sky *skyBox = new Sky; and then I use this successfully in the main.cpp skyBox->RenderSkyBox(); but then I want to know how I can delete the pointer reference to prevent leak of memory? I have a CleanD3D function in main.cpp, and I tried this in their: delete[] skyBox; but when im exiting my application im getting a problem on this line. It shows a dialog box saying: Debug Assertion Failed! Then it gives me option of Abort/Retry/Fail. And says to click Retry to debug. I do that and it says Application triggered a breakpoint (when it doesnt even have a breakpoint) and points to the delete[] line! Im not even sure if its possible to do what im trying to do, because from most websites ive seen only array pointers being deleted and not class objects. And im a bit confused if i can use delete[] where I am trying to use it or is it only allowed to be used in a destructor?!? Thanks guys for your kind help.

Hi,

You just set the U and V coords to how many times you want it to repeat.

I was creating a terrain with a texture of size 1024x1024.

Therefore I simply set the repeat to 10 for it to repeat 10 times.

You set the U and V in the Vertex of the shape, for each side.

I hope thats clear? If not then let me know and i will post an example later on when im at home.
