The TDICondition component wraps multiple DirectX DICONDITION structures, which contain type specific information for force feedback effects that have the DIEFT_CONDITION option set.

It is used to define 'Conditions', which are forces that are applied in response to the movement or position of a control device's input mechanisms.

There are four standard types of conditions - friction, damper, inertia and spring.

Use this component by setting TDIEffect::TypeSpecificParams to refer to either a single TDICondition component or one TDICondition component per axis associated with a condition.

To create a condition, use the TDx_InputDevice::CreateEffect() method and pass one of the following as the GUID parameter:

GUID_Spring
GUID_Damper
GUID_Inertia
GUID_Friction

The properties should be interpreted according to the type of condition the component represents.

To setup this component, first set the TDICondition::ArraySize property, then set each property using array indexes, eg:

// create internal storage for 5 DICONDITION structures

DICondition1->ArraySize = 5;

// fill each array with appropriate data

for (int i=0;i<5;i++)
/{
DICondition1->PositiveCoefficient[i] = 1;
DICondition1->NegativeCoefficient[i] = -1;
/}
