The Dispose action will dispose the currently loaded texture. This frees up computer resources, but the texture will no longer be usable. Note that multiple Drawables can use the same texture, and disposing of it will get rid of the texture information not just for this Drawable, but any Drawable that is using the texture. Dispose should be used when a texture will not be used again. Here are some guide lines for when you should or should not dispose a Drawable: 1. If the Drawable was loaded using Load(text) or Load(File), then the Drawable created new texture data when it was loaded. This can be safely disposed, unless you copied the Drawable, e.g. with Load(Drawable). 2. If the Drawable was loaded as a shape, e.g. with the LoadRectangle action, the Drawable created new texture data when it loaded. It can be safely disposed, unless you copied the Drawable, e.g. with Load(Drawable). 3. If the Drawable was loaded using a Texture or a TextureRegion, such as with the Load(Texture) action, then it is NOT safe to dispose this if there are any other Drawables that are still in use which were also loaded with the same Texture. If there are no other Drawables that were loaded with the Texture, it is safe to dispose. If a texture was used to load multiple Drawables, it is good practice to use the Dispose action directly from the Texture once all of the Drawables are no longer in use. 4. If the Drawable was loaded with an ImageSheet, you should NEVER dispose the Drawable's texture. All Drawables loaded from an ImageSheet use the same Texture data, so disposing of any Drawable from an ImageSheet will delete the ImageSheet's texture data. If you ever wish to dispose an ImageSheet's texture data, it is good practice to use the ImageSheet's Dispose action.

Return

boolean

This action is used to indicate that an Item and all Items that were added to it should not be visible on the screen. Note that the Item class on its own cannot be drawn on the screen, but classes that inherit from it such as Libraries.Game.Graphics.Drawable can be. By default, Items are considered visible.

This action returns whether or not this Item accepts mouse input. If the value is true, this will intercept incoming mouse events, triggering any related MouseListeners and InputSets and preventing the mouse event from propagating to other Items on the Layer. The default value is true.

Return

boolean: True if this Item can receive mouse events, or false otherwise.

This action returns the nearest parent object that is accessible. This can be anything that the programmer wants to be accessible, from user interface components in a 2D interface to 3D components relative in 3-space on screen. By default, items have no accessible parent and are self-contained, but user interface components normally override the behavior so that controls can be logically nested within each other. attribute: returns Item

Return

boolean:

The IsClipping action returns true if pixel clipping is enabled, or false if it is disabled. If it is enabled, when the Item and its children are drawn as part of the QueueForDrawing action, any pixels that would be drawn outside of the unrotated dimensions of the Item are not rendered. In other words, the Item will only draw inside the exact rectangle formed by its x, y position and its width and height.

Return

boolean: True if this item is collidable, false otherwise

When this value is true, the Item is responsible for determining its rendering via the Draw(Painter2D) action -- if this action isn't overridden, the Item and its children won't be drawn. This is an advanced feature only necessary for complex custom components, and most users will not need to use this functionality.

boolean: Whether or not this Item is currently using custom drawing rules.

This action returns whether or not any items are contained in this Item.

Return

boolean:

This action sets this item's angular velocity in radians per second. Physics must be enabled in this item before using this action.

This action changes the accessibility code for this Item. This should be done with care because setting the accessiblity code to the incorrect type can cause accessibility to stop functioning or, in some cases, cause the program to crash.

Parameters

• integer newAccessibilityCode: the new accessibility code for this Item.

This action sets a custom accessibility role description for this item. This should only be done if there is not a standard accessibility code for the type of item being implemented. If the item behaves very similarly to a standard control type, then set the accessibility code to that standard type while also setting the role description. For example, if implementing an item that extends Control, is keyboard focusable, and responds to activation via both mouse clicks and the Space key, like a button, but it shouldn't be described as a button, then set the accessibility code to BUTTON and the custom role description to whatever is appropriate. If there isn't a suitable accessibility code, or if in doubt, set the accessibility code to CUSTOM.

The SetChildrenProcessingMouseEvents action is used to set whether or not children items should receive mouse events if this Item is using custom drawing.

This is an advanced feature only necessary for complex custom components, and most users will not need to use this.

Parameters

The SetClipping action is used to enable or disable clipping. If it is enabled, when the Item and its children are drawn as part of the QueueForDrawing action, any pixels that would be drawn outside of the unrotated dimensions of the Item are not rendered.

The IsClipping action returns true if pixel clipping is enabled, or false if it is disabled. If it is enabled, when the Item and its children are drawn as part of the QueueForDrawing action, any pixels that would be drawn outside of the unrotated dimensions of the Item are not rendered.
