natiny.input.get_touch_pressed

Lua
natiny.input.get_touch_pressed(touch) -> pressed

Returns true only on the frame when the specified touch first contacts the screen.

Parameters

Name Type Description
touch number Touch identifier from natiny.input.get_touch_at

Returns

Type Description
boolean true on the touch's first frame; false on later frames or for an invalid identifier

Example

Lua
for i = 0, natiny.input.get_touch_count() - 1 do
    local touch = natiny.input.get_touch_at(i)
    if natiny.input.get_touch_pressed(touch) then
        fire(natiny.input.get_touch_x(touch), natiny.input.get_touch_y(touch))
    end
end

Notes

  • A touch that starts and ends between two frames returns true here and from natiny.input.get_touch_released in the same frame.
  • Touch input is available on Android and in touch-enabled browsers.
  • The first active touch is also reported as the left mouse button. Do not process both APIs unless duplicate input is intended.
