Cloning is a feature that allows a sprite to create a clone, or semi-duplicate, of itself, while the project is running. This can be useful in tower defense games, for example, for a wave of objects. Clones of a sprite will be the same as the original, or parent sprite, but as a separate instance. Clones inherit the parent's scripts, costumes, sounds, and properties, but can then be modified. There is a limit of 300 clones per project to prevent excessive lagging or crashes,[1] but 301 can be made. <\/p>\n
In Scratch 2.0, there are three blocks related to cloning. All can be found in the Control palette. <\/p>\n
This block will clone the sprite it runs in. Its version in the Scratch Day 2011 prealpha had no dropdown insert to select a sprite. <\/p>\n
It is also possible to clone other clones recursively. <\/p>\n
This Hat Block activates when a clone is created. It only runs in the newly created clone, not previous clones or the parent. <\/p>\n
This Cap Block will delete the clone it runs in. <\/p>\n
Not to be confused with cloning, sprites can be duplicated by two methods: <\/p>\n
This will make the new sprite appear in the new sprites area with all of the same costumes, scripts, and sounds. <\/p>\n
Variables for all sprites will be the same for each clone, but variables for this sprite only will be different for each clone. <\/p>\n
There are two different types of cloning implemented in different Scratch modifications. They are commonly referred to as \"Panther-style cloning\", and \"BYOB-style cloning\". <\/p>\n
In Panther-style cloning, a clone inherits its parent's properties, but is only a clone of it, not a new sprite. Other sprites can sense the clones, using the Touching ()? block, with the parent as its argument. The code for Panther-style cloning was actually implemented in Scratch 1.4, hinting that it was a planned feature, but wasn't added. Scratch 2.0 uses this style of cloning. <\/p>\n
In BYOB-style cloning, a clone is a new sprite in the sprite list, with editable data all of its own. Clones are created with an Operators block \"(clone)\", which clones a sprite and reports a reference to it, which can then be used to control it. <\/p>\n
