Represents a mouse or a pen movement.

<description>

|
Stores information about a mouse or a pen motion. This includes relative position, absolute position, and velocity. See [method Node._input].
|
|
[b]Note:[/b] By default, this event is only emitted once per frame rendered at most. If you need more precise input reporting, set [member Input.use_accumulated_input] to [code]false[/code] to make events emitted as often as possible. If you use InputEventMouseMotion to draw lines, consider implementing [url=https://en.wikipedia.org/wiki/Bresenham%27s_line_algorithm]Bresenham's line algorithm[/url] as well to avoid visible gaps in lines if the user is moving the mouse quickly.

<member name="pen_inverted" type="bool" setter="set_pen_inverted" getter="get_pen_inverted" default="false">
|
|
Returns [code]true[/code] when using the eraser end of a stylus pen.
|
|
[b]Note:[/b] This property is implemented on Linux, macOS and Windows.
|
|
</member>
|
|
<member name="pressure" type="float" setter="set_pressure" getter="get_pressure" default="0.0">
|
|
Represents the pressure the user puts on the pen. Ranges from [code]0.0[/code] to [code]1.0[/code].
|

|
|
<member name="relative" type="Vector2" setter="set_relative" getter="get_relative" default="Vector2(0, 0)">
|
|
The mouse position relative to the previous position (position at the last frame).
|
|
[b]Note:[/b] Since [InputEventMouseMotion] is only emitted when the mouse moves, the last event won't have a relative position of [code]Vector2(0, 0)[/code] when the user stops moving the mouse.
|
|
[b]Note:[/b] [member relative] is automatically scaled according to the content scale factor, which is defined by the project's stretch mode settings. This means mouse sensitivity will appear different depending on resolution when using [member relative] in a script that handles mouse aiming with the [constant Input.MOUSE_MODE_CAPTURED] mouse mode. To avoid this, use [member screen_relative] instead.
|
|
</member>
|
|
<member name="screen_relative" type="Vector2" setter="set_screen_relative" getter="get_screen_relative" default="Vector2(0, 0)">
|
|
The unscaled mouse position relative to the previous position in the coordinate system of the screen (position at the last frame).
|
|
[b]Note:[/b] Since [InputEventMouseMotion] is only emitted when the mouse moves, the last event won't have a relative position of [code]Vector2(0, 0)[/code] when the user stops moving the mouse. This coordinate is [i]not[/i] scaled according to the content scale factor or calls to [method InputEvent.xformed_by]. This should be preferred over [member relative] for mouse aiming when using the [constant Input.MOUSE_MODE_CAPTURED] mouse mode, regardless of the project's stretch mode.
|
|
</member>
|
|
<member name="screen_velocity" type="Vector2" setter="set_screen_velocity" getter="get_screen_velocity" default="Vector2(0, 0)">
|
|
The unscaled mouse velocity in pixels per second in screen coordinates. This velocity is [i]not[/i] scaled according to the content scale factor or calls to [method InputEvent.xformed_by]. This should be preferred over [member velocity] for mouse aiming when using the [constant Input.MOUSE_MODE_CAPTURED] mouse mode, regardless of the project's stretch mode.
|
|
</member>
|
|
<member name="tilt" type="Vector2" setter="set_tilt" getter="get_tilt" default="Vector2(0, 0)">
|
|
Represents the angles of tilt of the pen. Positive X-coordinate value indicates a tilt to the right. Positive Y-coordinate value indicates a tilt toward the user. Ranges from [code]-1.0[/code] to [code]1.0[/code] for both axes.
|
|
</member>
|
|
<member name="velocity" type="Vector2" setter="set_velocity" getter="get_velocity" default="Vector2(0, 0)">
|
|
The mouse velocity in pixels per second.
|
|
[b]Note:[/b] [member velocity] is automatically scaled according to the content scale factor, which is defined by the project's stretch mode settings. This means mouse sensitivity will appear different depending on resolution when using [member velocity] in a script that handles mouse aiming with the [constant Input.MOUSE_MODE_CAPTURED] mouse mode. To avoid this, use [member screen_velocity] instead.
