  • #include "Drawer.h" void Drawer::DrawEntity(Entity& entity, TextureManager* texture_manager, SDL_Renderer * renderer){ texture_manager->Draw(entity.GetSprite(), entity.GetPosition(), renderer); } It acts like a mediator between TexureManager(wich draws texures) and Entity wich has all the information like position, scale, etc.

  • > Using SDL_UpdateTexture over SDL_Lock/UnlockTexture uses 5% less CPU time. I think the use-case for this was that "locking" a texture was useful when you had to read back the pixels (since SDL would cache a copy in RAM, you didn't have to read it back from the GPU), but at a minimum, "streaming" was an unfortunate choice of words, since it implies write-only semantics, which is the opposite ...

  • SDL as a cross-platform layer (optional, use fplbase_stdlib if you initialize your own OpenGL context). MathFu for vector / matrix math. FlatBuffers for serialization. WebP for image loading. FPLUtil (optional, can be used to build). googletest (only in unit tests). Download. Download using git or from the releases page.
  • Using SDL_UpdateTexture () I do something along the lines of (in a loop): const unsigned char *frame_data = function_that_gets_frame_using_ffmpeg (); SDL_UpdateTexture (texture, NULL, frame_data, pitch); Where 'texture' is a single, streaming texture for the single renderer and window. Pitch is known as well.
  • SDL_Rect dest; //Where the texture will be drawn to on the screen dest. x = 100; dest. y = 100; dest. w = frames [0]-> w; dest. h = frames [0]-> h. All that’s left is to write a render loop and draw the current frame to the screen (incrementing the index each time). SDL_SetRenderDrawColor (renderer, 255, 255, 255, 0); //We'll be clearing the screen to black.
  • check whether all texture objects are resident, if not, either decrease the quality of them (bits, remove alpha channel, resolution, etc.) or their number. Note that you have to change the target format of the texture object, not the SDL surface quality. Then redo step 3,4.
  • Now, just press Enter and the SDL library will be downloaded onto your system. Next, we'll download the GLEW library, but since we've already downloaded it in the previous section, you can refer to that. If you want a quick review on downloading GLEW, you can refer to the Downloading the GLFW and GLEW libraries for a Mac section.
  • You can also set your own width and height values to shrink or stretch the texture as desired. /** * Draw an SDL_Texture to an SDL_Renderer at position x, y, preserving * the texture's width and height * @param tex The source texture we want to draw * @param ren The renderer we want to draw to * @param x The x coordinate to draw to * @param y ...
  • For no apparent reason, you are filling your loaded image with a solid white color using SDL_FillRect. Also, you seem to clear the renderer without rerendering the texture. You need to SDL_RenderCopy the texture again after clearing the renderer.
  • Here is an example using SDL that shows how to pass YUV420 data to a fragment shader, which then converts it to RGB to write it to the framebuffer: /* * Very simple example of how to perform YUV->RGB (YCrCb->RGB) * conversion with an OpenGL fragmen shader.
  • Second, the resulting texture is a static texture and its pixels can only be modified through SDL_UpdateTexture(), which is also a slow operation. Therefore, it is not recommended to run it to render every frame.

Flans mod star warsc++,image,textures,sdl. Pass nullptr in for srcrect in your SDL_RenderCopy() call: SDL_RenderCopy(renderer_, image_, nullptr, &imgrect); Right now if x and/or y are larger than image_ SDL will clip srcrect to the extents of image_, end up with an empty rect, and do nothing. Now we employ stock SDL directory structure (i.e. include/SDL for includes and sdl-config for configuration binary) - Update graphics/sdl_ttf to version 2.0.8 - Update graphics/sdl_image to version 1.2.5 - Update audio/sdl_mixer to version 1.2.7 - Update net/sdl_net to version 1.2.6 - Update Mk/bsd.sdl.mk accordingly - Fix dependent ports to fit the new directory structure and avoid several API breakages - Bump up portrevisions for all dependent ports to allow them to be upgraded by ...
This is actually a common issue that I see popup every once in a while. You want to load in your images using SDL_image (or just SDL), but you then need to turn that surface into an OpenGL texture.

  • If this is not the case, i.e. if you want to update only a part of the texture, you can specify the coordinates of the sub-rectangle that you want to update. You can refer to the documentation for further details. When using OpenGL extensions with SDL, it is of vital importance that you define NO_SDL_GLEXT before including SDL\SDL_opengl.h. Failure to do this will make most of the later extensions inaccessible by the methods described in this document.

Remarks. If provided, texw and texh will be filled with the width and height values suitable for the provided texture. In most cases, both will be 1.0, however, on systems that support the GL_ARB_texture_rectangle extension, these values will actually be the pixel width and height used to create the texture, so this factor needs to be taken into account when providing texture coordinates to ...

  • E.g. if you select render target 0 then the texture display will update to show the currently bound render target 0 regardless of which texture that is. If the slot you are following becomes unbound or unused, the previous texture will still be displayed up until you select a different pipeline slot, or the slot is bound again.

Procedure: update-rect surface x [y [w [h]]] Update surface within a specified rectangle.
