Including a Shader
A shader is a program that runs on the GPU and is used to course of information, akin to vertices, pixels, or textures. You need to use shaders to create customized results, akin to altering the colour of an object or including a texture to it.
So as to add a shader to a button, it’s worthwhile to:
- Create a brand new shader file.
- Write the shader code within the file.
- Add the shader file to the button’s “Shader” property.
Right here is an instance of a shader code that you should use to alter the colour of a button:
| Shader Code |
|---|
|
“` void most important() { gl_FragColor = vec4(1.0, 0.0, 0.0, 1.0); } “` |
This shader code will make the button pink. You may change the colours within the code to alter the colour of the button.
Including a shader to a button can provide you extra management over the feel and appear of the button. You need to use shaders to create customized results that aren’t potential with the built-in properties of the button.
Assigning a Contact Occasions Operator
