Macro Definition Documentation

CAM_DEFAULT_COLLISION_SIZE

#define CAM_DEFAULT_COLLISION_SIZE   20

Initial collision size for camera (check MAP_CELL_SIZE for size relation)

CAM_DEFAULT_INIT_ANGLE

#define CAM_DEFAULT_INIT_ANGLE   0

Initial camera vision angle (0 means bro is seeing right)

P_COLOR

#define P_COLOR   COLOR_YELLOW

The camera is yellow because reasons

Function Documentation

draw_camera()

void draw_camera

(

void

)

Draw the camera in the screen in the actual camera position.

Note

The camera is represented as a yellow dot with a line in front of him. This line represent the face of the camera.

get_camera_angle()

float get_camera_angle

(

void

)

Returns the current camera angle of vision (in radians)

get_camera_direction()

trc_world_position_t get_camera_direction

(

void

)

Returns the current camera direction, in the form of a normalized vector

get_camera_position()

trc_world_position_t get_camera_position

(

void

)

Returns the current camera position

move_camera_colliding()

void move_camera_colliding

(

const trc_world_position_t

velocity

)

Moves the camera with the given velocity, will stop fucking moving if a collision is detected

move_camera_sliding()

void move_camera_sliding

(

const trc_world_position_t

velocity

)

Moves the camera with the given velocity, will slide along the walls if a collision is detected

open_door()

void open_door

(

void

)

Check if is a door infront of the camera. If that's true, opens the door

reset_camera_info()

void reset_camera_info

(

void

)

Sets the camera info to the current level

Note

If you change or reset the level, call this function to update the camera position, velocity, etc

rotate_camera()

void rotate_camera

(

const float

rotation_delta

)

Rotates the camera adding the given delta to the current camera angle

Note

The sign of rotation_delta determines the direction of the rotation

Variable Documentation

trc_camera

trc_transform_t trc_camera

The camera info, like the position and actual direction of movement
