beginFrame()
engine/Source/Scene/CreditDisplay.js 521

Resets the credit display to a beginning of frame state, clearing out current credits.

destroy()
engine/Source/Scene/CreditDisplay.js 586

Destroys the resources held by this object. Destroying an object allows for deterministic release of resources, instead of relying on the garbage collector to destroy this object.

Once an object is destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception. Therefore, assign the return value (undefined) to the object as done in the example.
Throws:
  • DeveloperError : This object was destroyed, i.e., destroy() was called.

endFrame()
engine/Source/Scene/CreditDisplay.js 559

Sets the credit display to the end of frame state, displaying credits from the last frame in the credit container.

isDestroyed() → boolean
engine/Source/Scene/CreditDisplay.js 603

Returns true if this object was destroyed; otherwise, false.

返回值:
true if this object was destroyed; otherwise, false.

removeStaticCredit(credit)
engine/Source/Scene/CreditDisplay.js 481

Removes a static credit shown on screen or in the lightbox.
参数名称 类型 描述信息
