-## Custom layer effects
+## Custom RGB Matrix Effects
+
+By setting `RGB_MATRIX_CUSTOM_USER` (and/or `RGB_MATRIX_CUSTOM_KB`) in `rule.mk`, new effects can be defined directly from userspace, without having to edit any QMK core files.
+
+To declare new effects, create a new `rgb_matrix_user/kb.inc` that looks something like this:
-Custom layer effects can be done by defining this in your `<keyboard>.c`:
+`rgb_matrix_user.inc` should go in the root of the keymap directory.
+`rgb_matrix_kb.inc` should go in the root of the keyboard directory.
```C
-void rgb_matrix_indicators_kb(void) {
- rgb_matrix_set_color(index, red, green, blue);
+// !!! DO NOT ADD #pragma once !!! //
+
+// Step 1.
+// Declare custom effects using the RGB_MATRIX_EFFECT macro
+// (note the lack of semicolon after the macro!)
+RGB_MATRIX_EFFECT(my_cool_effect)
+RGB_MATRIX_EFFECT(my_cool_effect2)
+
+// Step 2.
+// Define effects inside the `RGB_MATRIX_CUSTOM_EFFECT_IMPLS` ifdef block
+#ifdef RGB_MATRIX_CUSTOM_EFFECT_IMPLS
+
+// e.g: A simple effect, self-contained within a single method
+static bool my_cool_effect(effect_params_t* params) {
+ RGB_MATRIX_USE_LIMITS(led_min, led_max);
+ for (uint8_t i = led_min; i < led_max; i++) {
+ rgb_matrix_set_color(i, 0xff, 0xff, 0x00);
+ }
+ return led_max < DRIVER_LED_TOTAL;
+}
+
+// e.g: A more complex effect, relying on external methods and state, with
+// dedicated init and run methods
+static uint8_t some_global_state;
+static void my_cool_effect2_complex_init(effect_params_t* params) {
+ some_global_state = 1;
}
+static bool my_cool_effect2_complex_run(effect_params_t* params) {
+ RGB_MATRIX_USE_LIMITS(led_min, led_max);
+ for (uint8_t i = led_min; i < led_max; i++) {
+ rgb_matrix_set_color(i, 0xff, some_global_state++, 0xff);
+ }
+
+ return led_max < DRIVER_LED_TOTAL;
+}
+static bool my_cool_effect2(effect_params_t* params) {
+ if (params->init) my_cool_effect2_complex_init(params);
+ return my_cool_effect2_complex_run(params);
+}
+
+#endif // RGB_MATRIX_CUSTOM_EFFECT_IMPLS
```
-A similar function works in the keymap as `rgb_matrix_indicators_user`.
+For inspiration and examples, check out the built-in effects under `quantum/rgb_matrix_animation/`
