Hi together,
I am new to this list. So perhaps I should introduce myself. I am
25 year old german student studying congitive neuroscience in
Utrecht/Netherlands. I want to use squeak /etoys mainly for
exploring and visualizing some ideas in a quick way.
Right now I want to build a prototype for an experiment and think
that this is a good project to learn a bit more about squeak.
I want to program a sequence of objects appearing on different
positions on the screen one after the other and later in a random
order.
A very dirty way to do so is just script doing something like.
object1 show.
script wait for 1000ms.
object1 hide
object2 show
script wait for 1000ms.
I know that this is a very basic question but couldn't find the
answer, as I don't know what it is I am looking for.
Waiting inside a script is not supported in this version of etoys.
What you can do instead is this:
script ticking once a second, for an object with a variable named i
* increase i by 1
* Test i = 1 Yes: obj1 show
* Test i = 2 Yes: obj1 hide, obj2 show
* Test i = 3 Yes: set i to 0
