Question to print a message with loop

How do I print text on the screen using a for loop?.

Please provide context and example (or complete attempted codes). The reason I am not giving any type of answer immediately here is because a for loop will complete within a single act frame -- so it would be like printing the entire text string at once. Maybe you have some reason for using a loop. I just don't know; therefore more information would be helpful in determining the best response.

Problems with <iframe>

By Bolla13, with no replies.

I've embedded a Greenfoot Scenario in a own website. Unfortunately my game does not react after a second start. Mouse input does not work. I have to clear the cache first, but then sometimes it does not always work. Could it be because I test my website with localhost. Or is there a kind of refresh for <iframe>? I just realized that I have to refresh the site in Firefox, Edge and also in IE.????? Does this have to do with <iframe>?

Pause scenario and manually remove B from world (right-click on it and select Delete from drop-down). Then drag another actor to where the removed actor would be added and hit the Run button.

When I create the variable in line 34 I get this error: java.lang.IndexOutOfBoundsException: Index 0 out of bounds for length 0 << Code Omitted >>

It is trying to tell you that the returned list is empty and therefore you cannot get any element from it. First check to ensure the list is NOT empty before trying to get an element from it.

Fixed it. Thanks for the explanation.
