Function Documentation

addPosition()

void systems::transform::addPosition	(	const unsigned int &	id,
		const glm::vec3 &	offset )

Adds an offset to the position of the given entity.

Parameters

id	the entity id
offset	the position offset to be added

addRotation()

void systems::transform::addRotation	(	const unsigned int &	id,
		const glm::vec3 &	offset )

Adds an offset to the rotation of the given entity.

It works the same way of updateRotation.

See also

systems::transform::updateRotation()

Parameters

id	the entity id
offset	the rotation offset to be added

addScale()

void systems::transform::addScale	(	const unsigned int &	id,
		const glm::vec3 &	offset )

Adds an offset to the scale of the given entity.

Parameters

id	the entity id
offset	the scale offset to be added

getModelMatrix()

glm::mat4 systems::transform::getModelMatrix

(

const unsigned int &

id

)

Retrieves the model matrix of the given entity.

If the model matrix is dirty it will be updated by the component automatically.

Parameters

id	the entity id

Returns

the entity model matrix

getPosition()

glm::vec3 systems::transform::getPosition

(

const unsigned int &

id

)

Retrieves the position of the given entity.

Parameters

id	the entity id

Returns

the entity position

getRotation()

glm::vec3 systems::transform::getRotation

(

const unsigned int &

id

)

Retrieves the rotation of the given entity.

Parameters

id	the entity id

Returns

the entity rotation in Euler angle.

getScale()

glm::vec3 systems::transform::getScale

(

const unsigned int &

id

)

Retrieves the scale of the given entity.

Parameters

id	the entity id

Returns

the entity scale

updateModelMatrix()

void systems::transform::updateModelMatrix

(

const unsigned int &

id

)

Updates the model matrix of the given entity.

If the model matrix is dirty it will update the model matrix and also the entity collider if it has one.

Parameters

id	the entity id

updatePosition()

void systems::transform::updatePosition	(	const unsigned int &	id,
		const glm::vec3 &	position )

Updates the position of the given entity.

Parameters

id	the entity id
position	the entity new position

updateRotation()

void systems::transform::updateRotation	(	const unsigned int &	id,
		const glm::vec3 &	rotation )

Updates the rotation of the given entity.

It takes an Euler angle glm::vec3 in degrees and it will be converted in radians by the component.

Parameters

id	the entity id
rotation	the entity new rotation in degrees

updateScale()

void systems::transform::updateScale	(	const unsigned int &	id,
		const glm::vec3 &	scale )

Updates the scale of the given entity.

Parameters

id	the entity id
scale	the entity new scale
