Constructor & Destructor Documentation

◆ PolylightNode()

PolylightNode::PolylightNode ( const std::string &  name)
explicit

Use PolylightNode() to construct a new PolylightNode object.

Member Function Documentation

◆ compare_to()

int PolylightNode::compare_to ( const PolylightNode other) const

Returns a number less than zero if this PolylightNode sorts before the other one, greater than zero if it sorts after, or zero if they are equivalent.

Two PolylightNodes are considered equivalent if they consist of exactly the same properties Otherwise, they are different; different PolylightNodes will be ranked in a consistent but undefined ordering; the ordering is useful only for placing the PolylightNodes in a sorted container like an STL set.

◆ disable()

void PolylightNode::disable ( )
inline

Disable this light.

Definition at line 62 of file polylightNode.I.

◆ enable()

void PolylightNode::enable ( )
inline

Enable this light.

Definition at line 54 of file polylightNode.I.

◆ flicker()

LColor PolylightNode::flicker ( ) const

If flickering is on, the do_poly_light function in PolylightNodeEffect will compute this light's color based on the variations applied in this function Variation can be sin or random Use offset, scale and step_size to tweak Future addition: custom function variations to flicker.
