Hello all, I have a shader that takes the alpha value of one texture and applies to a sprite frame. Do render Textures not support alpha in cocos? Basic masking functionality without using the mask component.

Hello all, I have a shader that takes the alpha value of one texture and applies to a sprite frame. Anyhow, the shader works, I can set it up on a spriteframe and it works as expected… however, when I add the render text. Basic masking functionality without using the mask component.

But the render overhead is quite high compare to sprite even when I set timeScale = 0 and cache to SHARE_CACHE. Hi, in my game I used alot of spine animation. I don’t want to create separate for that spine to save memory usage. So how can I optimize this? Thanks in advance.

Hello, I tried to use the cocos2d-x preset, but I got a weird render for the SpriteRenderer. (I I see that I have to disable the Trim for the Sprite component here: TexturePacker, the trim lost the positions ). The left sprite is a normal.png. The 2 others sprites are from texture packer. They are stretched and cropped.

With change FXAA to TAA, I got different result: FXAA => black background around 3D model. TAA => transparent background around 3D model.

I export the rendered terrain from Blender as a RGBA image but with alpha value set to depth. The graphics backend rewrite took a while. However, the situation is now good. Everything is just one big texture. This gives me freedom in level design and saves work making tiles… tileable. So it’s RGBZ.

To explain the idea of how shaders work, let's consider a very simple shader for drawing a sprite to the screen. Our sprite is 32x32 pixels in size, and it must be drawn at some position. The following OpenGL code sends the sprite to the shader for drawing: OpenGL Commands. Multiply by 2. Substract (1, 1). 1 range for drawing).

Firstly, Sprite is a quad, the mesh is static for easier usage. You can have a custom render component and make its mesh with multiple quad, but it really isn’t necessary. You can achieve gradient color within one quad. Just calculate color step in the fragment shader is enough.

Analysis The whole effect can be split into two parts, one for the simulation of the mesh and one for the rendering of the mesh. Rendering is even more straightforward, just use the Graphic component and draw lines directly. Combined with the knowledge of the rendering, the texture is actually very close to the rendering vertex data.

When a game is “published”, the number of pixels rendered, and the aspect ratio used, are determined by the device that the game is running on, such as a television screen, web page, or even mobile device. Any remaining space that appears as a result of mis-matched aspect ratios, will just be left rendering black pixels.
