在raylib中使用着色器时，对象未根据鼠标位置移动

我正在使用着色器在raylib中创建一些发光粒子，粒子应该随鼠标移动，但在编译时，它会卡在左下角，粒子不会移动。

的外观

c++代码

#include <raylib.h>
#include <vector>

const int W = 400;
const int H = 400;
std::vector<Vector2> particle;
float remap(float value, float low1, float high1, float low2, float high2) {
return low2 + (value - low1) * (high2 - low2) / (high1 - low1);
}
int main() {
SetConfigFlags( FLAG_WINDOW_RESIZABLE );
InitWindow(W, H, "FireWorks");
Shader shader = LoadShader("../assets/vert.glsl", "../assets/frag.glsl");
Texture2D texture = LoadTextureFromImage(GenImageColor(W, H, BLUE));
int resolLoc = GetShaderLocation(shader, "resolution");
int particleLoc = GetShaderLocation(shader, "particle");
int particleCountLoc = GetShaderLocation(shader, "particleCount");
float res[2] = {(float)W, (float)H};
SetShaderValue(shader, resolLoc, res, SHADER_UNIFORM_VEC2);
SetTargetFPS(60);
while (!WindowShouldClose()) {
BeginDrawing();
ClearBackground(BLACK);
particle.push_back(Vector2{(float)GetMouseX(), (float)GetMouseY()});
int removeCount = 1;
for (int i = 0; i < removeCount; i++) {
if (particle.size() == 0) break;
if (particle.size() > 30) {
particle.erase(particle.begin() + i);
}
}
BeginShaderMode(shader);
float particles[30][2];
for ( int i = 0; i < particle.size(); i++) {
particles[i][0] = remap(particle[i].x, 0, W, 0.0, 1.0);
particles[i][1] = remap(particle[i].y, 0, H, 1.0, 0.0);
}
int pSize = particle.size();
SetShaderValue(shader, particleCountLoc, &pSize, SHADER_UNIFORM_INT);
SetShaderValue(shader, particleLoc, particles, SHADER_UNIFORM_VEC2);
DrawTextureRec(texture, (Rectangle) { 0, 0, (float)texture.width, (float) -texture.height }, (Vector2) { 0, 0}, RAYWHITE);
DrawRectangle(0, 0, W, H, BLACK);
EndShaderMode();
EndDrawing();
}
UnloadTexture(texture);
UnloadShader(shader);
CloseWindow();
return 0;
}

in vec4 fragColor;
// Input uniform values
uniform sampler2D texture0;
uniform vec4 colDiffuse;

float value = float(i) / distance(st, particlePos.xy) * 0.00015;  
g += value * 0.5;
b += value;
}
}

finalColor = vec4(r, g, b, 1.0) * texelColor * colDiffuse;
}

JS版本的代码(有效(在这里。

如果你能给我指一个正确的方向，那就太好了。
