I still can't call this class as an object in XNA
Here is the working code in the initialize function where I try to create it. But in my draw code it still doesn't let me go:
tileclipping.draw_texture(...);

I'm sorry if it isn't clear what i'm trying to do. I'm trying to capture a 2d texture (or create one) OUTSIDE my game class I'm trying to use a class as a handler, to pass these texture2d's back and forth between GAME1 and my Renderer I don't WANT to have all my textures inside my main class. Also another thing with this is that I'm trying to basically have a generic texture2d CREATOR.
Aka this isn't for something simple like rendering sprites. The function of RENDERER is to either create a new TEXTURE2D object with a NEW render target object based on parameters fed to this function:
public RenderTarget2D new_texture(int width, int height)
{
Texture2D TEX = new Texture2D(GraphicsDevice, width, height); //create the texture to render to
RenderTarget2D Mine = new RenderTarget2D(GraphicsDevice, width, height);
GraphicsDevice.SetRenderTarget(Mine); //set the render device to the reference provided
//maybe base.draw can be used with spritebatch. Idk. We'll see if the order of operation
//works out. Wish I could call base.draw here.
return Mine; //I'm hoping that this returns the same instance and not a copy.
}
I need a way of creating a copy of the renderer class WITHOUT having it in the gamecomponents list. The reason is because XNA won't let me access Graphics device, which is a required parameter OF a texture2D object. So basically i'm doing all this stuff as a work around just becuase Texture2D requires graphics device as a parameter and I can't willy nilly pass GraphicsDevice INTO an instance of my renderer class i've already tried that and it fails.
So there will be situations in my game where say
if (Camera_zoom==1){
scaling_texture.dispose();
scaling_texture = tileclipping.new_texture(camera_width*camera_zoom, camera_height*camera_zoom);
// call a refresh command here
this.refresh_scene(...) //Inside here is a ton of sprite batches because the render target is now set to NEW scaling_texture
//after that we do the drawing using spritebatch inside draw function of main game class
//expecting that a render texture is provided for us by these pre requisites.
//then after that we call the render command
//it returns the render target to the screen
//then in the draw command AFTER the sprite batches were drawn TO the target surface called scaling_texture
//We use various parameters to tell it to draw this scaling_texture as a spritebatch.draw() inside the
//game1 draw class
//So basically I want to do things in this order
/// Create new texture of variable size
// use it as render target
// Do all my spritebatch
// call another spritebatch
//draw the contents of said texture on the screen as the rendering target
//Dispose of the texture object
//Check the scaling size of it
//Re create the scaling texture with a NEW resolution (each frame)
//Select it as a render target
//Do the spritebatchy stuff all over again repeat above for all game loop
//BUT I want parts of this, mainly the creation of this Texture2D object, and the drawing of it to the backbuffer
//To all happen inside my Renderer class
//but for all main game spritebatches to happen inside my main game class
//This is a problem for me and XNA doesn't seem to want to let me organize it this way
//Unless i'm missing something which is why i'm making this lengthy post
//ANY and all help is appreciated.
//Thanks again and I hope I explained myself well enough this time IE my intentions.
//PLEASE NOTE I am SET on doing things THIS way. I will NEED a texture 2d rendering target that is NON static
//During MOST of my GAME project.
//That said.. IT HAS TO have function to wrap it inside Renderer. THere is no way in hell I'm going to do this
//In a spaghetti code fashion Inside GAME1 with nested if statements.
//Thanks all
}
