Kaleidoscope Effect

// Kaleidoscope Effect Code 🌈✨

// Create Event
// Create a surface with the dimensions of the room to draw the effect.
surface = surface_create(room_width, room_height);


// Step Event
// Handle window resizing
// If the room size changes, recreate the surface to match the new dimensions.
if (surface_get_width(surface) != room_width || surface_get_height(surface) != room_height) {
    if (surface_exists(surface)) surface_free(surface); // Free the existing surface to avoid memory leaks.
    surface = surface_create(room_width, room_height); // Create a new surface with updated dimensions.
}


// Draw Event
// Ensure the surface exists before drawing.
if (!surface_exists(surface)) {
    surface = surface_create(room_width, room_height);
}

// Set the surface as the target for drawing.
surface_set_target(surface);

// Draw a point at the mouse position to create a dynamic effect.
draw_point(mouse_x, mouse_y);

// Reset the drawing target back to the application surface.
surface_reset_target();

// Draw the kaleidoscope effect by mirroring parts of the surface.
// First, draw the base surface.
draw_surface(surface, 0, 0);

// Draw mirrored parts of the surface to create the kaleidoscope effect.
draw_surface_part_ext(surface, 0, 0, room_width, room_height, room_width, 0, -1, 1, c_white, 1); // Mirror horizontally.
draw_surface_part_ext(surface, 0, 0, room_width, room_height, room_width, room_height, -1, -1, c_white, 1); // Mirror both horizontally and vertically.
draw_surface_part_ext(surface, 0, 0, room_width, room_height, 0, room_height, 1, -1, c_white, 1); // Mirror vertically.
