Detailed Description

What's A Microgame?

Microgames are single-screen, single-objective games lasting around 5 seconds, designed to be presented to the player in rapid-fire fashion. Cosplay Crunch is a collection of cosplay- and crafting-themed microgames, intended to mirror the frantic pace of last-minute crafting.

Design Considerations

Microgames should have a cosplay/crafting theme, but eclectic visual, audio, and gameplay design is encouraged. Gameplay-wise, microgames should have a single objective that is clearly conveyed to the player through choice of verb and visual cues. A frustrated player is not a returning player. Keep in mind that a microgame that seems well-balanced when played in isolation might feel unfair when the player is rapidly context switching between games. Accessibility is also important to consider, e.g., don't rely on audio being heard.

Writing A Microgame

Microgames are implemented similarly to pared-down Swadge modes: they have a similar init/main loop/deinit cycle that is managed by the Cosplay Crunch game mode. Microgames go through a series of states as defined in cosCrunchMicrogameState, allowing them time before gameplay to display helpful animations and time after gameplay to congratulate or taunt the player. Once a player succeeds or fails the microgame, send the result with cosCrunchMicrogameResult() to signify that the microgame is over. If you don't send a result, the game will be failed once the timer runs out.

Data Structures
struct	cosCrunchMicrogame_t
	The definition for a Cosplay Crunch microgame. Once your microgame is built, add this struct to the microgames[] array in cosCrunch.c to include it in the randomized rotation. While testing a microgame, you can comment out the other microgames in the array to play only yours on repeat. More...

Macros

Enumerations
enum	cosCrunchMicrogameState { CC_MG_GET_READY , CC_MG_PLAYING , CC_MG_CELEBRATING , CC_MG_DESPAIRING }

Functions
const tintColor_t *	cosCrunchMicrogameGetTintColor (void)
	Get a color set (base/highlight/lowlight) suitable for greyscale tinting to use for this microgame. Using tint colors is optional, but microgames that can easily swap colors (painting, drawing, etc.), especially if the colors can spill over onto the background, are encouraged to do so.
wsgPalette_t *	cosCrunchMicrogameGetWsgPalette (const tintColor_t *tintColor)
	Get a palette suitable for tinting a greyscale image using the drawWsgPalette*() functions from wsgPalette.h.
void	cosCrunchMicrogamePersistSplatter (wsg_t wsg, uint16_t x, uint16_t y)
	Microgames can leave paint, marker, glitter, and whatever else on the mat that persists across a play session. This will copy whatever is in your wsg to the background, where it will stay until it gets drawn over by another microgame or the current game session ends.
void	cosCrunchMicrogameResult (bool successful)
	Submit the player's result of the currently running microgame. Every microgame must have a success condition, but a failure condition is optional. The microgame timer running out will automatically send a failure result unless you implement fnMicrogameTimeout.

Data Structure Documentation

cosCrunchMicrogame_t

struct cosCrunchMicrogame_t

Data Fields
const char *	verb	The phrase that is flashed on the screen before the microgame runs. Should be an action: "Sew", "Glue", "Try not to cry", etc.
const char *	successMsg	The phrase that is flashed on the screen after the microgame if the game was succeeded. This can be NULL if you'd rather congratulate the player in a different manner.
const char *	failureMsg	The phrase that is flashed on the screen after the microgame if the game was failed. This can be NULL if you'd rather taunt the player in a different manner.
uint64_t	timeoutUs	How long the player has until they fail the microgame, in microseconds.
void(*)(void)	fnInitMicrogame	This function is called when this microgame is about to be started. It should initialize variables and load assets.
void(*)(void)	fnDestroyMicrogame	This function is called when the microgame is exited. It should free any allocated memory.
void(*)(int64_t elapsedUs, uint64_t timeRemainingUs, cosCrunchMicrogameState state, buttonEvt_t buttonEvts[], uint8_t buttonEvtCount)	fnMainLoop	This function is called from the main loop. The microgame should run its game logic and render like a mode would. This function should NOT call checkButtonQueueWrapper() like a mode would: it will receive all button events as an argument. Parameters elapsedUs The time elapsed since the last time this function was called. Use this value to determine when it's time to do things timeRemainingUs The time left until the game is failed state The current game state buttonEvts Button events that have occurred since the last main loop call buttonEvtCount The number of button events in the buttonEvts array
void(*)(int16_t x, int16_t y, int16_t w, int16_t h, int16_t up, int16_t upNum)	fnBackgroundDrawCallback	This function is called when the display driver wishes to update a section of the display. Implementing this function in your microgame is optional and will cause the Cosplay Crunch UI to render over it in the foreground. If you do not implement this function, your game will render on top of the cutting mat background. Note that your microgame will not receive this callback for the entire screen: any pixels at the bottom of the display that are covered up by the Cosplay Crunch UI will be skipped. Parameters x The x coordinate that should be updated y The y coordinate that should be updated w The width of the rectangle to be updated h The height of the rectangle to be updated up Update number upNum Update number denominator
bool(*)(void)	fnMicrogameTimeout	This function is called when the microgame timer expires. It is optional and intended for microgames that need to determine their success condition at the end of the game. If you implement this function, you can still call cosCrunchMicrogameResult() at any time to complete the game early. Returns true if the microgame was completed successfully, false if it was failed

Macro Definition Documentation

CC_DRAWABLE_HEIGHT

#define CC_DRAWABLE_HEIGHT   (TFT_HEIGHT - 38)

The height in pixels of the area that microgames can draw on without invading the UI space. Note that UI elements (timer and calendar, and desk if fnBackgroundDrawCallback is implemented) will still draw on top of microgames.

Enumeration Type Documentation

cosCrunchMicrogameState

enum cosCrunchMicrogameState

Enumerator
CC_MG_GET_READY	This state is shown briefly with the game's verb overlaid before the game starts to orient the player. The game should render and can accept player input to telegraph what buttons will do, but should not use the input to affect the game state yet.
CC_MG_PLAYING	The game is in progress: accept input, render the game, all that jazz.
CC_MG_CELEBRATING	The player has succeeded. Display something that elevates their spirits.
CC_MG_DESPAIRING	The player has failed. Display something that underscores their torment.

Function Documentation

cosCrunchMicrogameGetTintColor()

const tintColor_t * cosCrunchMicrogameGetTintColor

(

void

)

Get a color set (base/highlight/lowlight) suitable for greyscale tinting to use for this microgame. Using tint colors is optional, but microgames that can easily swap colors (painting, drawing, etc.), especially if the colors can spill over onto the background, are encouraged to do so.

This function returns a different color set every time, so microgames should only call this once to get the color assigned to them.

Returns

A pointer to a tint color set

cosCrunchMicrogameGetWsgPalette()

wsgPalette_t * cosCrunchMicrogameGetWsgPalette

(

const tintColor_t *

tintColor

)

Get a palette suitable for tinting a greyscale image using the drawWsgPalette*() functions from wsgPalette.h.

Parameters

tintColor

Returns

A pointer to a palette that can be used to tint a wsg

cosCrunchMicrogamePersistSplatter()

void cosCrunchMicrogamePersistSplatter	(	wsg_t	wsg,
		uint16_t	x,
		uint16_t	y )

Microgames can leave paint, marker, glitter, and whatever else on the mat that persists across a play session. This will copy whatever is in your wsg to the background, where it will stay until it gets drawn over by another microgame or the current game session ends.

Your microgame's destroy callback is a good place to call this from, since no drawing takes place while games are being switched out. You can also call this multiple times during gameplay if building up splatter incrementally would work better for your microgame.

Parameters

wsg	An image with transparency to be copied onto the background
x	Screen x coordinate to draw
y	Screen y coordinate to draw

cosCrunchMicrogameResult()

void cosCrunchMicrogameResult

(

bool

successful

)

Submit the player's result of the currently running microgame. Every microgame must have a success condition, but a failure condition is optional. The microgame timer running out will automatically send a failure result unless you implement fnMicrogameTimeout.

Parameters

successful

Whether the player completed the game or failed
