// Making your own ProxyGen suitable for visualizing class YourObject. |
|
// |
|
// Derive YourObjectProxy() from ProxyGen. |
|
// YourObjectProxy() should set fProxyMsgType and the colors fAmbient,fColor, either |
|
// in the constructor or in Init(). |
|
// Implement IGetNode() (see below). |
|
// Implement ICreateProxy() (see below). |
|
// Implement a CreateProxy() member to YourObject (see below). |
|
// Add DrawableType kYourObjectProxy to plDrawable.h |
|
// Add console commands under Graphics.Show.YourObjectProxy. |
|
// |
|
// See plLightSpace and plLightProxy for examples. |
|
// |
|
// More details. |
|
// ============ |
|
// To make your own ProxyGen, you should subclass plProxyGen and override Init() |
|
// because you'll probably want to keep a pointer to your owner (of type only you |
|
// need to understand). |
|
// |
|
// The IGetNode() function lets your owner specify which plSceneNode to place the |
|
// drawable in. That will normally just return your owner's GetSceneNode() call. |
|
// |
|
// ICreateProxy() let's your ProxyGen do any tweaking before calling CreateProxy() |
|
// on your object. Your ProxyGen::ICreateProxy() could just do the work itself, but |
|
// normally doesn't have enough protected information to really do the job. |
|
// |
|
// Typically your object's CreateProxy() function will just translate its internal |
|
// data to a form suitable for the plDrawableGenerator suite of helper functions |
|
// and return the result of a call into one of them. |
|
// |
