# Touch Input Module
|
||
|
|
|
||
|
|
**Note: TouchInputModule is obsolete. Touch input is now handled in [StandaloneInputModule](script-StandaloneInputModule).**
|
||
|
|
|
||
|
|
This module is designed to work with touch devices. It sends pointer events for touching and dragging in response to user input. The module supports multitouch.
|
||
|
|
|
||
|
|
The module uses the scene configured Raycasters to calculate what element is currently being touched over. A raycast is issued for each current touch.
