Hi,
From an Etoys SCRIPT, how can I create a 'duplicate' of a player
(equivalent to clicking on the green halo icon), rather than creating a 'sibling/clone' of a player (equivalent to SHIFT-clicking on the green halo icon)? The 'copy' tile available under the miscellaneous category seems to create a clone; the textual equivalent of ''Playfield include Ellipse's copy' is 'self include: Ellipse getNewClone'. What I need is the textual equivalent that would create a 'duplicate' rather than a 'clone'.
[Why do I care? In the course that I'm currently teaching, we've created a 'robot' with embedded 'sensors' (the 'robots' and 'sensors' are created from individual Ellipse morphs; the sensors then get embedded in the robot). The robot's actions depend on differences between left and right sensor values. If I now make a 'duplicate' of the robot using the green halo icon, the new robot works as expected. However, if I make a 'clone' of the robot (either by SHIFT-clicking the green halo icon, or by using the 'copy' tile in a script, the new robot seems to pick up the sensor values from the original robot, rather than from its own sensors.]
Thanks in advance, --Mark Nelson
Hi, you have to use do menu item tile in the category miscellanous and choose duplicate as item.
This seems create a copy in the hand.
If you want just create a new robot this will work. But there is no handle on the new created object this way.
however once dropped it can be designated as the first element of the morph containing it.
Regards

Thanks for the tip. That's getting closer to what I need, but in my application the robots need to be able to 'reproduce' without any user interaction. Having a robot 'in hand' isn't going to work for this purpose.
The robots autonomously explore their environment collecting food/energy and once they have acquired enough energy, they reproduce (generate a copy of themselves). I have the reproduction algorithm working fine with the 'copy' tile, but I have the problem that the embedded sensors of the child robot seem to be linked back to the parent's sensors, rather than the child's own sensors.
If you have any other ideas along these lines, please let me know. Thanks, --Mark

Hi, Mark,
You're right that there's no direct programatic way using tiles alone to obtain a proper "duplicate" (as opposed to a "sibling,") except (as Pierre-André suggests) by using "do menu item - duplicate," which, unsatisfactorily, leaves the clone in the "hand" rather than allowing you programatically to place it where you wish.
However, by using a one-line textual script, you can get the desired effect.
The trick is to devote a "Player-valued" variable to "remember" the newly-created thing, so that you can send messages to it to set it up the way you want.
In the example below, Robot has been given a player-valued variable named "theDuplicate." The one-line textual script creates a duplicate of the Robot and places it into the "theDuplicate" variable. Each time this script is run, a new copy of the robot is made, and placed into the originating robot's "theDuplicate" variable.
In order for the newborn to be seen on the screen, it needs to be put somewhere visible, and this is done by "including" it in the desired container, and positioning it appropriately; all of this can be done with normal tiles.
Thus, for example, the following script first invokes the textual one- liner to create a copy, then adds the copy to the container, and, finally, positions the copy at an offset to the upper-right of the original robot.
Hope this helps!
Cheers,
-- Scott

I dont see 'duplicate' entry in my version of etoys (2.3#1885). Is this controlled by any Preference setting?

Hi, Subbu,
You'll see it in the menu only if the eToyFriendly preference is false, in which case it can be found in the "halo actions..." submenu.
But even if eToyFriendly is *true*, making "halo actions..." not visible via the UI, you can still invoke it via do-menu-item.

Thank you, Scott and Andre. This option totally slipped my mind.
Scott's solution using a textual script is really neat. The playfield already keeps track of collections of Robots, so we could use it to track duplicates. The duplicate's position can be computed based on the cursor or count.
E.g. Playfield>>makeDuplicate self includeAtCursor: self getValueAtCursor costume duplicate player. self getValueAtCursor turn: 45; forward: 10; turn: 45

Hi Mark --
We should have done this better.
Here is how I handle things that are "like this" this may or may not work for your case.
If you build a bunch of components on a Playfield it is smart enough to act as a little name-space, so when it is copied all the links between the components will be preserved in the new composite object. (Again, we should do this better.)
So e.g. if you have an object that is controlled by a joystick morph, you can put both of these in a Playfield, copy the Playfield, and the new object and the new joystick will be linked.
Cheers,
Alan
