Syntax
[RequireComponent(typeof(EventSystem))]
public abstract class BaseInputModule : UIBehaviourFields
m_InputOverride
Declaration
protected BaseInput m_InputOverrideField Value
| Type | Description |
|---|---|
| BaseInput |
m_RaycastResultCache
Declaration
[NonSerialized]
protected List<RaycastResult> m_RaycastResultCacheField Value
| Type | Description |
|---|---|
| List<RaycastResult> |
Properties
eventSystem
Declaration
protected EventSystem eventSystem { get; }Property Value
| Type | Description |
|---|---|
| EventSystem |
input
The current BaseInput being used by the input module.
Declaration
public BaseInput input { get; }Property Value
| Type | Description |
|---|---|
| BaseInput |
inputOverride
Used to override the default BaseInput for the input module.
Declaration
public BaseInput inputOverride { get; set; }Property Value
| Type | Description |
|---|---|
| BaseInput |
Remarks
With this it is possible to bypass the Input system with your own but still use the same InputModule. For example this can be used to feed fake input into the UI or interface with a different input system.
sendPointerHoverToParent
True if pointer hover events will be sent to the parent
Declaration
protected bool sendPointerHoverToParent { get; set; }Property Value
| Type | Description |
|---|---|
| bool |
Methods
ActivateModule()
Called when the module is activated. Override this if you want custom code to execute when you activate your module.
Declaration
public virtual void ActivateModule()ConvertPointerEventScrollDeltaToTicks(Vector2)
Converts PointerEventData.scrollDelta to corresponding number of ticks of the scroll wheel.
Declaration
public virtual Vector2 ConvertPointerEventScrollDeltaToTicks(Vector2 scrollDelta)Parameters
| Type | Name | Description |
|---|---|---|
| Vector2 | scrollDelta |
Returns
| Type | Description |
|---|---|
| Vector2 |
Remarks
Input Module implementations are free to apply a scaling factor to their PointerEventData's scrollDelta. This method can be used when a system needs to treat scaling-independent input values.
ConvertUIToolkitPointerId(PointerEventData)
Returns Id of the pointer following PointerId convention.
Declaration
public virtual int ConvertUIToolkitPointerId(PointerEventData sourcePointerData)Parameters
| Type | Name | Description |
|---|---|---|
| PointerEventData | sourcePointerData | PointerEventData whose pointerId will be converted to UI Toolkit pointer convention. |
Returns
| Type | Description |
|---|---|
| int |
