A structure that contains a template for a condition effect.

Data Fields

Header

Uint16

type

one of the effects handled by this structure; see Remarks for details

SDL_HapticDirection

direction

direction of the effect - not used at the moment; see Remarks for details

Replay

Uint32

length

duration of the effect

Uint16

delay

delay before starting the effect

Trigger

Uint16

button

button that triggers the effect

Uint16

interval

how soon it can be triggered again after button

Condition

Uint16

right_sat

level when joystick is to the positive side; max 0xFFFF

Uint16

left_sat

level when joystick is to the negative side; max 0xFFFF

Sint16

right_coeff

how fast to increase the force towards the positive side

Sint16

left_coeff

how fast to increase the force towards the negative side

Uint16

deadband

size of the dead zone; max 0xFFFF: whole axis-range when 0-centered

Sint16

center

position of the dead zone

Code Examples

Remarks

type may be one of the following:

SDL_HAPTIC_SPRING

effect based on axis position

SDL_HAPTIC_DAMPER

effect based on axis velocity

SDL_HAPTIC_INERTIA

effect based on axis acceleration

SDL_HAPTIC_FRICTION

effect based on axis movement

direction is (currently) 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.
