set a default value for initialisation, otherwise it will be garbage. This is needed when new element are generated, but not from an emitter for example, when you set this scheme to a LocatedBindable that does have a least one instance in it example : CPSDot *d = new CPSDot; CPSAttribMakerMemory<RGBA> *genAttribMaker = new CPSAttribMakerMemory<RGBA>; genAttribMaker->setScheme(CPSColorBlender(CRGBA::White, CRGBA::Black) Now, if an emitter emit these particle, it'll start to emit white ones, and then black ones d->setColorScheme( genAttribMaker); now, suppose that there were several dot instanciated before the setScheme is performed : d->newElement(); no color has been memorized for this element, so when setScheme is performed, it has to generate one There are no emitter that provides it, so its taken from the default value Note : this should only be useful in an editor, that allow the user to change the scheme with a running system ...
