vertex_position_3d(buffer, x, y, z);
| 参数 | 描述 |
|---|---|
| buffer | The buffer to write the information to. |
| x | The x position. |
| y | The y position. |
| z | The z position. |
返回： N/A（无返回值）
This function will add 3D position data to the vertex currently
being defined for the custom primitive. You supply the buffer to
write the data into as well as the x, y and z position for
drawing.
vertex_position_3d(buff, x - 100, y - 125, 0);
The above code will set the position of the vertex being defined.
