How to get a button to start painting

Dear friends,

I've a student developping a project to teach some basic math concepts. In her proposal, it's needed a button to start drwaing things using the etoys paintbox. Because it will be needed several times I can't recommend the "do menu item" "repaint".

Anny suggestiont to help solve this problem will be appreciated.

Luis

Re: How to get a button to start painting

Hi,

If I understood your problem correctly, I think you can create an empty drawing and in the button script put something like this:

[ Sketch | copy | do menu item | repaint ]

So now, when you click the button you'll be repainting a copy of the original sketch and you can use it many times.

Cheers,

Richo

Hi Luis,
The attached project works with repaint buttons for two objects, more as needed.

Kathleen,

Nice! After all this time I am still learning new things about Etoys.

Re: How to get a button to start painting

Steve,
Also, there is a way to detach the Halo handles and they still function but I can't remember exactly and didn't rediscover it in a hurried 5 minutes of keystroke combo clicks. I bet someone knows and will tell.

It is one of those examples that prove that every-thing-is-an-object.
On that topic, my young students are realizing that they can deconstruct and modify things like the All Scripts button; a gateway moment that leads to other experiments.

Re: How to get a button to start painting

Hi Kathleen and Richo,

Many thanks for your help. I solved this problem with the hint of Richo.

I made a 1 pixel paint and use it as source. After that I copy and repaint this copy. It's fine!

Thanks again

Luis
