Detailed Description

Input layer implementation.

Definition in file input.c.

Typedef Documentation

input_state

typedef struct input_state input_state

State of the input system.

Function Documentation

input_initialize()

b8 input_initialize

(

void

)

Initialize the input system.

Prepares the internal state to process and serve input information. Must be called once before using the input system.

Returns

false if an error occurred, true if succesful

Definition at line 43 of file input.c.

Here is the call graph for this function:

input_is_key_down()

b8 input_is_key_down

(

key_code

key

)

Check if a key is currently down.

Parameters

key	the key_code of the key to check

Returns

true if the key is currently down, false otherwise

Definition at line 57 of file input.c.

input_is_key_held()

b8 input_is_key_held

(

key_code

key

)

Check if a key is held.

A key is being held when it was down and is currently still down.

Parameters

key	the key_code of the key to check

Returns

true if the key is held, false otherwise

Definition at line 77 of file input.c.

input_is_key_up()

b8 input_is_key_up

(

key_code

key

)

Check if a key is currently up.

Parameters

key	the key_code of the key to check

Returns

true if the key is currently up, false otherwise

Definition at line 67 of file input.c.

input_mouse_moved()

b8 input_mouse_moved	(	u32 *	x,
		u32 *	y
	)

Check if mouse moved.

Parameters

x	points to x delta of the mouse since last update, will be populated by the function
y	points to y delta of the mouse since last update, will be populated by the function

Returns

false if mouse did not move since last update, true if it moved

Definition at line 87 of file input.c.

input_mouse_position()

void input_mouse_position	(	u32 *	x,
		u32 *	y
	)

Get current mouse position.

Parameters

x	points to x coordinate of the mouse, will be populated by the function
y	points to y coordinate of the mouse, will be populated by the function

Definition at line 82 of file input.c.

input_mouse_wheel()

i8 input_mouse_wheel

(

void

)

Get current mouse wheel scrolling direction.

Returns

1 if scrolling down, -1 if scrolling up, 0 if no input

Definition at line 93 of file input.c.

input_process_key()

void input_process_key	(	key_code	key,
		b8	pressed
	)

Set current state for a key.

Parameters

key	the key_code of the key to update
pressed	the current state of the key

Definition at line 95 of file input.c.

input_process_mouse_position()

void input_process_mouse_position	(	u32	x,
		u32	y
	)

Set current state for the mouse position.

Parameters

x	the current x coordinate of the mouse
y	the current y coordinate of the mouse

Definition at line 100 of file input.c.

input_process_mouse_wheel()

void input_process_mouse_wheel

(

i8

wheel_pos

)

Set current scrolling wheel direction for the mouse.

Parameters

wheel_pos

the current direction of the mouse wheel

Definition at line 105 of file input.c.

input_update()

void input_update

(

f64

delta_time

)

Updates the input system.

This should be called every frame before prolling window events.

Parameters

delta_time

the time that passed since the last update

Definition at line 51 of file input.c.

Here is the call graph for this function:

input_was_key_down()

b8 input_was_key_down

(

key_code

key

)

Check if a key was down before the last update.

Parameters

key	the key_code of the key to check

Returns

true if the key was down, false otherwise

Definition at line 62 of file input.c.

input_was_key_up()

)

Check if a key was up before the last update.

Parameters

key	the key_code of the key to check

Returns

true if the key was up, false otherwise

Definition at line 72 of file input.c.
