TouchCount ( )

Parameters

None.

Description

Returns the number of contacts still down in the current snapshot. A tap that has already ended is available through GetTouchEvent instead. Enumerate 1 through this count and obtain stable IDs with TouchID.

iOS and Android provide native touch and acceleration, and web pages on phones and tablets provide touch. Other backends return neutral data. Read the mobile input guide for lifecycle and snapshot rules.
