 				Returns a [KinematicCollision2D], which contains information about a collision that occurred during the last call to [method move_and_slide].

 				Adds a new multistate item with text [param label].
 				Contrarily to normal binary items, multistate items can have more than two states, as defined by [param max_states]. The default value is defined by [param default_state].
 				An [param id] can optionally be provided, as well as an accelerator ([param accel]). If no [param id] is provided, one will be created from the index. If no [param accel] is provided, then the default value of 0 (corresponding to [constant @GlobalScope.KEY_NONE]) will be assigned to the item (which means it won't have any accelerator).

 				Starts an edit for multiple carets. The edit must be ended with [method end_multicaret_edit]. Multicaret edits can be used to edit text at multiple carets and delay merging the carets until the end, so the caret indexes aren't affected immediately. [method begin_multicaret_edit] and [method end_multicaret_edit] can be nested, and the merge will happen at the last [method end_multicaret_edit].
