The TDIConstantForce component wraps the DirectX DICONSTANTFORCE structure, which contains type specific information for force feedback effects that have the DIEFT_CONSTANTFORCE option set.

It is used to define a 'Constant Force', which is a force that has a defined magnitude and duration.

You can apply an envelope to a constant force but not an offset.

Only the magnitude of the force is defined by this component, the duration is set in TDIEffect::Duration.

Use this component by setting TDIEffect::TypeSpecificParams to refer to a single TDIConstantForce component.

To create a constant force, use the TDx_InputDevice::CreateEffect() method and pass the following as the GUID parameter:

GUID_ConstantForce

    ErrorValue
    Magnitude
    Size

    Clear
