Как добавить шейдер на фон в фнф

скрипт на шейдер: #pragma header //uniform float tx, ty; // x,y waves phase //modified version of the wave shader to create weird garbled corruption like messes uniform float uTime = 0; /** * How fast the waves move over time */ uniform float uSpeed = 2; /** * Number of waves over time */ uniform float uFrequency = 5; /** * How much the pixels are going to stretch over the waves */ uniform float uWaveAmplitude = 0.1; vec2 sineWave(vec2 pt) { float x = 0.0; float y = 0.0; float offsetX = sin(pt.y * uFrequency + uTime * uSpeed) * (uWaveAmplitude / pt.x * pt.y); float offsetY = sin(pt.x * uFrequency - uTime * uSpeed) * (uWaveAmplitude / pt.y * pt.x); pt.x += offsetX; // * (pt.y - 1.0); // ﹤- Uncomment to stop bottom part of the screen from moving pt.y += offsetY; return vec2(pt.x + x, pt.y + y); } void main() { vec2 uv = sineWave(openfl_TextureCoordv); gl_FragColor = texture2D(bitmap, uv); }
