|
---|
| 39 | @remarks
|
---|
| 40 | A Skeleton, like a Mesh, is shared between Entity objects and simply updated as required
|
---|
| 41 | when it comes to rendering. However there are times when you want to attach another object
|
---|
| 42 | to an animated entity, and make sure that attachment follows the parent entity's animation
|
---|
| 43 | (for example, a character holding a gun in his / her hand). This class simply identifies
|
---|
| 44 | attachment points on a skeleton which can be used to attach child objects.
|
---|
| 45 | @par
|
---|
| 46 | The child objects themselves are not physically attached to this class; as it's name suggests
|
---|
| 47 | this class just 'tags' the area. The actual child objects are attached to the Entity using the
|
---|
| 48 | skeleton which has this tag point. Use the Entity::attachMovableObjectToBone method to attach
|
---|
| 49 | the objects, which creates a new TagPoint on demand.
