Heyo,
I tried to incorporate a Dialogue screen into a game of mine. After each level there will be small box where text will be written with a typewriter effect. Currently I try to get the program to change to the next dialogue text by clicking on the box. For that I am using an integer which I use as the index for a list with the dialogue. When I click on the box the integer will increase by one. Currently I have the problem that I can increase the integer, yet, somehow the next text doesn't get displayed, even after implementing a method which resets the variables for the text.
Down below I will include all necessary code. I hope that someone can make out where the mistake lies and help me implementing a functioning dialogue and dialogue box.

{
super(600, 800, 1);

level = leveldb;
if(leveldb == 0)
{
dialogue.add("Test1");
dialogue.add("Test2");
dialogue.add("Test3");
}
