+# Flipper helper functions
+
+A collection of methods my games are using. 
+
+---
+
+## UI
+
+Extra methods for graphics. It can read/write/copy anything from the screen, create a buffer that you can swap with the one inside the canvas object and every flipper draw call should work with it.
+
+Call this at the end of your program
+```
+ui_cleanup();
+```
+
+### How to use it
+
+* To test if a pixel is black or not: ``test_pixel(canvas_buffer, pixel_x, pixel_y, screen_width)``
+* Convert Flippers icon to the same type to u8g2: ``uint8_t * result=image_data(canvas, icon);``
+* Flatten X/Y pixel coordinate to array index ``uint32_t result=pixel_index(x, y)``
+* Draw icon region with overlay/invert support: ``draw_icon_clip(canvas, icon, image_x, image_y, screen_x, screen_y, width, height, draw_mode)``
+* Draw flipped region icon with overlay/invert support: ``draw_icon_clip_flipped(canvas, icon, image_x, image_y, screen_x, screen_y, width, height, draw_mode)``
+* Draw rounded box: ``draw_rounded_box(canvas, x, y, width, heigth, draw_mode)``
+* Draw rounded box frame: ``draw_rounded_box_frame(canvas, x, y, width, heigth, draw_mode)``
+* Draw rectangle: ``draw_rectangle(canvas, x, y, width, heigth, draw_mode)``
+* Invert screen colors in a rectangle: ``invert_rectangle(canvas, x, y, width, height)``
+* Invert screen colors in a shape: ``invert_shape(canvas, image, x, y, width, height)``
+* Read pixel: ``read_pixel(canvas, x, y)``
+* Set pixel: ``set_pixel(canvas, x, y, draw_mode)``
+* Draw line: ``set_pixel(canvas, x1, y1, x2, y1, draw_mode)``
+* Test coordinate if it is in the screen: ``in_screen(x, y)``
+* Test coordinate if it is in the screen: ``in_screen(x, y)``
+* Get screen buffer: ``get_buffer(canvas)``
+* Create a new buffer: ``make_buffer()``
+* Clone buffer: ``clone_buffer(source_buffer, result_buffer)``
+
+---
+## Math (dml)
+
+Some extra math functionality.
+
+### Vector math
+
+* Vector type
+* add 2 vectors together ``Vector result = vector_add(a, b);``
+* divide 2 vectors components from each other ``Vector result = vector_sub(a, b);``
+* Multiplying vector components together ``Vector result = vector_mul_components(a, b);``
+* Dividing vector components ``Vector result = vector_div_components(a, b);``
+* Get the magnitude of a vector ``float result = vector_magnitude(a);``
+* Normalize a vector (components add up to one) ``Vector result = vector_normalized(a);``
+* Distance between vectors ``Vector result = vector_distance(a, b);``
+* Get dot product ``float result = vector_distance(a, b);``
+
+### Linear Interpolation
+
+* Interpolate a single value ``float result = lerp(start_value, end_value, time);``
+* Interpolate Vector ``Vector result = lerp(start_vector, end_vector, time);``
+* Quadratic interpolation ``Vector result = quadratic_2d(start_vector, control_vector, end_vector, time);``
+
+
+### Extra
+
+* min macro ``min(a,b);``
+* max macro ``max(a,b);``
+* abs macro ``abs(value);``
+
+---
+## Queue
+
+A basic queue functionality. Useful to chain your methods in order, so they can follow each other. Mainly used to state switching an animation state handling in my games.
+
+Currently it only supports one queue chain.
+### How to use it
+* Store a queue handler in your application state
+  ```c
+  typedef struct {
+      //...your game states
+      QueueState queue_state;
+  } AppState;
+  ```
+* To add a new queue item
+  ```c
+  //Needed functions
+  void done_callback(void *ctx) {
+     //Called when the item is being removed from the queue
+  }
+  void start_callback(void *ctx) {
+     //Called every tick when it is active
+  }
+  void render_callback(const void *ctx, Canvas *const canvas) {
+     //Called while rendering in case you want to render something
+  }
+  
+  //In your code somewhere
+  //Not needed callbacks can be set to NULL
+  enqueue(&(app_state->queue_state), app_state, done_callback, start_callback, render_callback, queue_run_duration)
+  ```
+* Required to run
+  ```c
+  //Put this in a place that runs every tick
+  bool queue_ran = run_queue(&(app_state->queue_state), app_state);
+  
+  //Put this in your render function
+  render_queue(&(app_state->queue_state), app_state, canvas);
+  ```
+* Clean up at the end of your program
+  ```c
+  queue_clear(&(app_state->queue_state));
+  ```
+
+---
+## Card
+
+### Types
+* Card
+  - Stores data about one card from the deck
+  - Properties
+    - pip: the symbol (0: spades, 1: hearths, 2: diamonds, 3: clubs)
+    - character: the letter for the card (2 is 0, A is 12)
+    - disabled: can be used freely. I used it to hide the card during animation
+    - flipped: if this is set to true, instead of the card graphics the backside will be rendered
+* Deck
+  - Store a whole deck
+  - Properties
+    - deck_count: How many decks are added into this
+    - cards: contains the cards
+    - card_count: how many cards are in the deck
+    - index: useful to track your current index in the deck
+* Hand
+  - Store cards that are given for example to the player
+  - Properties
+    - Cards: cards in the hand
+    - index: to keep track of where we are in the hand
+    - max: how many cards can be in the hand
+
+### Usage
+
+Before you can use it, you have to load the card_graphics.png file in your games assets
+```c
+    set_card_graphics(&I_card_graphics);
+```
+
+- Draw a single card: ``draw_card_at(pos_x, pos_y, pip, character, canvas)``
+- Draw single card with invert support: ``draw_card_at_colored(pos_x, pos_y, pip, character, inverted, canvas)``
+- Draw the blackjack deck in the bottom right corner (it can stack up to 21 cards): ``draw_deck(cards, count, canvas)``
+- Draw the backside of the card: ``draw_card_back_at(pos_x, pos_y, canvas)``
+- Generate a deck: ``generate_deck(deck_pointer, how_many_decks)``
+- Blackjack hand calculation: ``hand_count(cards_array, how_many_cards)``
+- Draw card animation state: ``draw_card_animation(card, from_vector, control_vector, to_vector, current_phase, extra_time_margin, canvas)``
+- Create hand pointer: ``init_hand(hand_pointer, card_count)``
+- Free hand pointer: ``free_hand(hand_pointer)``
+- Add card to the hand: ``add_to_hand(hand_pointer, card)``
+- Draw an empty space (like the one in solitaire): ``draw_card_space(pos_x, pos_y, is_highlighted, canvas)``
+- Draw cards in a column: ``draw_hand_column(hand, pos_x, pos_y, selected_card, canvas)``
+- Remove card from the deck: ``remove_from_deck(index_to_remove, deck_pointer)``
+- Get first non flipped card index in a hand: ``first_non_flipped_card(hand)``
+- Move cards from one hand to another starting at index: ``extract_hand_region(from_hand, to_hand, start_index)``lipped card index in a hand: ``first_non_flipped_card(hand)``
+- Move the whole hand into another hand: ``add_hand_region(from_hand, to_hand)``
