- Description
The CreateEffect() method will create and initialize an effect instance.
A return value of S_OK will be generated if the device is not acquired in exclusive mode. This indicates that the effect has been created and its parameters updated, but it may not have been downloaded to the device.
Error values that can be generated are:
DIERR_DEVICENOTREG
DIERR_DEVICEFULL
DIERR_INVALIDPARAM
DIERR_NOTINITIALIZED
- Parameters
RefGuid
The RefGuid parameter identifies the effect being created.
One of the predefined effects below or a GUID obtained from TDx_InputDevice::EnumEffects() can be used.
GUID_ConstantForce
GUID_RampForce
Periodic:
GUID_Square
GUID_Sine
GUID_Triangle
GUID_SawtoothUp
GUID_SawtoothDown
Conditions:
GUID_Spring
GUID_Damper
GUID_Inertia
GUID_Friction
User Defined:
GUID_CustomForce
EffectData
The EffectData parameter references a TDIEffect component holding the properties of the effect being created.
Set this property to NULL to create a blank effect object to be set later up using TDx_InputEffect::SetParameters().
NewEffect
The NewEffect parameter will reference the new TDx_InputEffect interface if the method returns successfully.
