A pointer to type-specific parameters, or NULL if there are no type-specific parameters.

```

## Discussion

If the effect is of type FFEFT_CONDITION, this member contains a pointer to an array of FFCONDITION structures that define the parameters for the condition. A single structure may be used, in which case the condition is applied in the direction specified in the rglDirection array. Otherwise, there must be one structure for each axis, in the same order as the axes in rgdwAxes array. If a structure is supplied for each axis, the effect should not be rotated; you should use the following values in the rglDirection array:

FFEFF_SPHERICAL: 0, 0, …

FFEFF_POLAR: 9000, 0, …

FFEFF_CARTESIAN: 1, 0, …

If the effect is of type FFEFT_CUSTOMFORCE, this member contains a pointer to a FFCUSTOMFORCE structure that defines the parameters for the custom force.

If the effect is of type FFEFT_PERIODIC, this member contains a pointer to a FFPERIODIC structure that defines the parameters for the effect.

If the effect is of type FFEFT_CONSTANTFORCE, this member contains a pointer to a FFCONSTANTFORCE structure that defines the parameters for the constant force.

If the effect is of type FFEFT_RAMPFORCE, this member contains a pointer to a FFRAMPFORCE structure that defines the parameters for the ramp force.
