Function Documentation

adjust_angle()

float adjust_angle

(

const float

angle

)

Returns the angle so it's in the range of 0 to 2*PI

Parameters

angle

The angle to adjust, in radians

angle_from_vector()

float angle_from_vector

(

trc_world_position_t

vector

)

Use the position given as a vector, and returns it's angle

are_equals()

bool are_equals	(	const float	f1,
		const float	f2
	)

Returns if the first float is equal to the second

Parameters

f1	First float
f2	Second float

distance_between()

float distance_between	(	const trc_world_position_t	p1,
		const trc_world_position_t	p2
	)

Returns the distance between p1 and p2

Parameters

p1	First point
p2	Second point

normalize_vector()

trc_world_position_t normalize_vector

(

const trc_world_position_t

vector

)

Returns the normalized vector

Note

If it is already normalized, returns one with the same parameters

scalar_multiplication()

trc_world_position_t scalar_multiplication	(	const trc_world_position_t	vector,
		const float	scalar
	)

Returns the given vector scaled by the given factor

trc_world_position_to_string_with_name()

char * trc_world_position_to_string_with_name	(	const trc_world_position_t	pos,
		const char *	pos_name
	)

Note

Remember to free the memory allocated for the string!

vector_length()

float vector_length

(

const trc_world_position_t

vector

)

Returns the distance between the origin and the given vector
