## Types
| Type | Description |
|---|---|
| [TSDLHaptic](../../sdl/sdl.sdlhaptic/tsdlhaptic) | A haptic device. |
| [TSDLHapticDirection](../../sdl/sdl.sdlhaptic/tsdlhapticdirection) | The direction where the force comes from, instead of the direction in which the force is exerted. |
| [TSDLHapticEffect](../../sdl/sdl.sdlhaptic/tsdlhapticeffect) | A generic template for any haptic effect. |
| [TSDLHapticConstant](../../sdl/sdl.sdlhaptic/tsdlhapticconstant) | A constant effect applies a constant force to the joystick in the specified direction. |
| [TSDLHapticPeriodic](../../sdl/sdl.sdlhaptic/tsdlhapticperiodic) | A wave-shaped effect that repeats itself over time. |
| [TSDLHapticCondition](../../sdl/sdl.sdlhaptic/tsdlhapticcondition) | A template for a condition effect. |
| [TSDLHapticRamp](../../sdl/sdl.sdlhaptic/tsdlhapticramp) | A template for a ramp effect. |
| [TSDLHapticLeftRight](../../sdl/sdl.sdlhaptic/tsdlhapticleftright) | Controls the large and small motors, commonly found in modern game controllers. |
| [TSDLHapticCustom](../../sdl/sdl.sdlhaptic/tsdlhapticcustom) | A custom force feedback effect. |
