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 |

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.
