class KX_2DFilterManager(EXP_PyObjectPlus)

2D filter manager used to add, remove and find filters in a scene.

addFilter(index, type, fragmentProgram)

Add a filter to the pass index index, type type and fragment program if custom filter.

Parameters:

• index (integer) – The filter pass index.

• type (integer) –

  The filter type, one of:

  • bge.logic.RAS_2DFILTER_BLUR

  • bge.logic.RAS_2DFILTER_DILATION

  • bge.logic.RAS_2DFILTER_EROSION

  • bge.logic.RAS_2DFILTER_SHARPEN

  • bge.logic.RAS_2DFILTER_LAPLACIAN

  • bge.logic.RAS_2DFILTER_PREWITT

  • bge.logic.RAS_2DFILTER_SOBEL

  • bge.logic.RAS_2DFILTER_GRAYSCALE

  • bge.logic.RAS_2DFILTER_SEPIA

  • bge.logic.RAS_2DFILTER_CUSTOMFILTER

• fragmentProgram (string) – The filter shader fragment program. Used only if type is bge.logic.RAS_2DFILTER_CUSTOMFILTER, if empty or not specified the filter is created without shader, waiting call to BL_Shader.setSourceList. (optional)

Returns:

The 2D Filter.

Return type:

KX_2DFilter

removeFilter(index)

Remove filter to the pass index index.

Parameters:

index (integer) – The filter pass index.

getFilter(index)

Return filter to the pass index index.

Warning:

If the 2D Filter is added with a SCA_2DFilterActuator, the filter will be available only after the 2D Filter program is linked. The python script to get the filter has to be executed one frame later. A delay sensor can be used.

Parameters:

index (integer) – The filter pass index.

Returns:

The filter in the specified pass index or None.

Return type:

KX_2DFilter or None
