|
|
* The final position and orientation of the entity, as contained in Location,
|
|
* is calculated from these values. By keeping the various transformations separate
|
|
* it's possible to undo or separate them when needed.
|
|
*
|
|
* This property will foremost contain transformations set on the entity itself,
|
|
* contained in mTranslate, mRotate and mTranslateScaled.
|
|
*
|
|
* In addition, external entities and components have the ability to add transformations
|
|
* through the "mExternal" map. It's expected that the keys used for entries in this map
|
|
* should be selected so that each entry is easily identified without any collisions.
