class
RenderEffects¶ Bases:
TypedWritableReferenceCountThis represents a unique collection of RenderEffect objects that correspond to a particular renderable state.
You should not attempt to create or modify a RenderEffects object directly. Instead, call one of the
make()functions to create one for you. And instead of modifying a RenderEffects object, create a new one.Inheritance diagram
-
isEmpty() → bool¶ Returns true if the state is empty, false otherwise.
-
getNumEffects() → size_t¶ Returns the number of separate effects indicated in the state.
Deprecated: in Python, use len(effects) instead, or effects.size() in C++.
- Return type
size_t
-
getEffect(type: TypeHandle) → RenderEffect¶ Looks for a RenderEffect of the indicated type in the state, and returns it if it is found, or NULL if it is not.
- Return type
-
getEffect(n: size_t) → RenderEffect Returns the nth effect in the state.
- Return type
-
size() → size_t¶ Returns the number of separate effects indicated in the state.
- Return type
size_t
-
findEffect(type: TypeHandle) → int¶ Searches for an effect with the indicated type in the state, and returns its index if it is found, or -1 if it is not.
-
static
makeEmpty() → RenderEffects¶ Returns a RenderEffects with no effects set.
- Return type
-
static
make(effect: RenderEffect) → RenderEffects¶ Returns a RenderEffects with one effect set.
- Return type
-
static
make(effect1: RenderEffect, effect2: RenderEffect) → RenderEffects Returns a RenderEffects with two effects set.
- Return type
-
static
make(effect1: RenderEffect, effect2: RenderEffect, effect3: RenderEffect) → RenderEffects Returns a RenderEffects with three effects set.
- Return type
-
static
make(effect1: RenderEffect, effect2: RenderEffect, effect3: RenderEffect, effect4: RenderEffect) → RenderEffects Returns a RenderEffects with four effects set.
- Return type
-
addEffect(effect: RenderEffect) → RenderEffects¶ Returns a new RenderEffects object that represents the same as the source state, with the new RenderEffect added. If there is already a RenderEffect with the same type, it is replaced.
- Return type
-
removeEffect(type: TypeHandle) → RenderEffects¶ Returns a new RenderEffects object that represents the same as the source state, with the indicated RenderEffect removed.
- Return type
-
output(out: ostream) → None¶
-
write(out: ostream, indent_level: int) → None¶
-
static
getNumStates() → int¶ Returns the total number of unique RenderEffects objects allocated in the world. This will go up and down during normal operations.
-
static
listStates(out: ostream) → None¶ Lists all of the RenderEffects in the cache to the output stream, one per line. This can be quite a lot of output if the cache is large, so be prepared.
-
static
validateStates() → bool¶ Ensures that the cache is still stored in sorted order. Returns true if so, false if there is a problem (which implies someone has modified one of the supposedly-const RenderEffects objects).

static
getClassType() → TypeHandle¶ - Return type
