love-touch

When to use this skill

Provides an interface to touch-screen presses. Use this skill when working with touch operations, multi-touch gestures, touch events, or any touch-related operations in LÖVE games.

Common use cases

• Handling touch screen input
• Implementing multi-touch gestures
• Working with touch-based game controls
• Managing touch events and callbacks
• Supporting mobile touch interfaces

Functions

• love.touch.getPosition(id: light userdata) -> x: number, y: number: Gets the current position of the specified touch-press, in pixels.
• love.touch.getPressure(id: light userdata) -> pressure: number: Gets the current pressure of the specified touch-press.
• love.touch.getTouches() -> touches: table: Gets a list of all active touch-presses.

Examples

Handling touch input

function love.touchpressed(id, x, y, dx, dy, pressure)
  -- Store touch position
  touches[id] = {x = x, y = y, pressure = pressure}

  -- Handle touch at position (x, y)
  handleTouchAt(x, y)
end

Multi-touch handling

function love.touchmoved(id, x, y, dx, dy, pressure)
  if touches[id] then
    -- Update touch position
    touches[id].x = x
    touches[id].y = y

    -- Handle drag gesture
    handleDrag(id, dx, dy)
  end
end

function love.touchreleased(id, x, y, dx, dy, pressure)
  -- Remove touch
  touches[id] = nil
end

Best practices

• Support both touch and mouse input for cross-platform compatibility
• Handle multi-touch gestures appropriately
• Consider touch interface design for mobile devices
• Test touch input on target platforms
• Be mindful of touch accuracy and precision

Platform compatibility

• Desktop (Windows, macOS, Linux): Touch support on touchscreen devices
• Mobile (iOS, Android): Full multi-touch support
• Web: Browser-based touch support
