vertex_colour(buffer, colour, alpha);
| 参数 | 描述 |
|---|---|
| buffer | The buffer to write the information to. |
| colour | The colour for this vertex (can be a constant or a hex value). |
| alpha | The alpha value for the vertex (from 0 to 1). |
返回： N/A（无返回值）
If your defined vertex format takes a colour value you can use this function to add that data to the vertex being defined for the current primitive. The function needs a buffer to store the data in and will take either a colour constant, or a hex value (using the standard GameMaker Studio 2 format of BGR, eg: $FF0000 for blue) as well as an alpha value from 0 (transparent) to 1 (fully opaque).
vertex_colour(b, c_white, 1);
The above code will set the vertex being defined to be white with an alpha value of 1.
