\brief A structure containing a template for a Condition effect.

The struct handles the following effects:

• ::SDL_HAPTIC_SPRING: Effect based on axes position.
• ::SDL_HAPTIC_DAMPER: Effect based on axes velocity.
• ::SDL_HAPTIC_INERTIA: Effect based on axes acceleration.
• ::SDL_HAPTIC_FRICTION: Effect based on axes movement.

Direction is handled by condition internals instead of a direction member. The condition effect specific members have three parameters. The first refers to the X axis, the second refers to the Y axis and the third refers to the Z axis. The right terms refer to the positive side of the axis and the left terms refer to the negative side of the axis. Please refer to the ::SDL_HapticDirection diagram for which side is positive and which is negative.

Fields

type_: Uint16

< ::SDL_HAPTIC_SPRING, ::SDL_HAPTIC_DAMPER, ::SDL_HAPTIC_INERTIA or ::SDL_HAPTIC_FRICTION

< Direction of the effect - Not used ATM.

length: Uint32

< Duration of the effect.

delay: Uint16

< Delay before starting the effect.

button: Uint16

< Button that triggers the effect.
