| Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index(). More...
|
|
bool | isExactType (TypeHandle handle) |
| Returns true if the current object is the indicated type exactly. More...
|
|
bool | isOfType (TypeHandle handle) |

Public Member Functions inherited from ReferenceCount |
int | getRefCount () |
| Returns the current reference count. More...
|
|
| ref () |
| Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. More...
|
|
bool | testRefCountIntegrity () |
| Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More...
|
|
bool | testRefCountNonzero () |
| Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
|
|
bool | unref () |
| Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More...

|
|
| setAlphaMode (EggRenderMode::AlphaMode mode) |
| Specifies precisely how the transparency for this geometry should be achieved, or if it should be used. The default, AM_unspecified, is to use transparency if the geometry has a color whose alpha value is non-1, or if it has a four-channel texture applied; otherwise, AM_on forces transparency on, and AM_off forces it off. The other flavors of transparency are specific ways to turn on transparency, which may or may not be supported by a particular rendering backend. More...
|
|
| setBin (str bin) |
| Sets the "bin" string for this particular object. This names a particular bin in which the object should be rendered. The exact meaning of a bin is implementation defined, but generally a GeomBin matching each bin name must also be specifically added to the rendering engine (e.g. the CullTraverser) in use for this to work. See also set_draw_order(). More...
|
|
| setDepthOffset (int bias) |
| Sets the "depth-offset" flag associated with this object. This adds or subtracts an offset bias into the depth buffer. See also DepthOffsetAttrib and NodePath::set_depth_offset(). More...
|
|
| setDepthTestMode (EggRenderMode::DepthTestMode mode) |
| Specifies whether this geometry should be tested against the depth buffer when it is drawn (assuming the rendering backend provides a depth buffer). Note that this is different, and independent from, the depth_write mode. More...
|
|

| Specifies whether writes should be made to the depth buffer (assuming the rendering backend provides a depth buffer) when rendering this geometry. More...
|
|
| setDrawOrder (int order) |
| Sets the "draw-order" flag associated with this object. This specifies a particular order in which objects of this type should be drawn, within the specified bin. If a bin is not explicitly specified, "fixed" is used. See also set_bin(). More...
|
|
| setVisibilityMode (EggRenderMode::VisibilityMode mode) |
| Specifies whether this geometry is to be considered normally visible, or hidden. If it is hidden, it is either not loaded into the scene graph at all, or loaded as a "stashed" node, according to the setting of egg-suppress-hidden. More...

|
| write (Ostream out, int indent_level) |
| Writes the attributes to the indicated output stream in Egg format. More...
