feedback_render()

virtual TouchIndex_t Wizt::Touchable::feedback_render ( VRenderContext &  Context, TouchIndex_t  StartIndex  ) const

render each touchable item of this object with a unique 32-bit RGBA encoding, starting with the StartIndex value.

Returns

The highest number used by this object. This number will be the start index of the next object.

bool Wizt::Touchable::pickAction ( TouchIndex_t  localIndex ) const

virtual

A virtual function that implements some action if the given index item is picked by the TouchList::pickAction() function.

Note that the localIndex is the item relative to this object, i.e. starting at zero.

Maybe pass Context/ValuePool as parameter here
