nice no replies
I noticed your post several times; but, I am not familiar with Legend of Zelda or Pokemon. I would rather ask how you want your text to display -- not how they are displayed in those games. You also need to attempt to do something code-wise along this line and then, when you run into an issue, ask for help (showing the code you used, giving detailed reports on any error messages, and describing what it is doing compared to what you want it to do.
A simple Dialog class might be something like this:
The code has been tested and corrected. The following would be an example of its use:
import greenfoot.*;
public class Dialog extends Actor
{
private String[] dialog;
public Dialog(String[] spokenLines)
{
dialog = spokenLines;
}
protected void addedToWorld(World world)
{
for (int i=0; i<dialog.length; i++)
{
dialog[i] += "\n\npress 'enter' to proceed";
GreenfootImage image = new GreenfootImage(dialog[i], 20, null, java.awt.Color.white);
image.drawRect(0, 0, image.getWidth()-1, image.getHeight()-1);
setImage(image);
while (!"enter".equals(Greenfoot.getKey())) Greenfoot.delay(1);
}
world.removeObject(this);
}
}String[] expressions = new String[]
{
"Man 1: Hey, there. Are you heading up that there road?",
"Man 2: As a matter of fact, yes. Why?",
"Man 1: You may want to find another way 'round.\nRumor has it, zombies be up there!",
"Man 2: Well, thanks very much. I appreciate the heads up."
};
getWorld().addObject(new Dialog(expressions), getX(), getY()-70);
i tried the code before but it doesnt display all of it on the screen and it cuts off and i also couldnt get it to move on to the next line of command
Things you can do:
(a) decrease the '20' on line 17 to make the textbox smaller; or,
(b) change were the dialog is placed in the world (line 8 in the second code-set); you can place it center-world using this:
or, (c) remove one of the new line escape sequences ( '\n' ) from the appending string to the dialog expression on line 16
getWorld().addObject(new Dialog(expressions), getWorld().getWidth()/2, getWorld().getHeight()/2);
so did what you said but i changed some colors and sizes basic stuff....but the dialog never seems to end...once im at the last line and i press enter it goes back to first i tried to make it check is its at the last line then when you press enter it just removes the whole thing
You need to place the second code-set above within an 'if' block to regulate the showing of the dialog. There are several ways to regulate it. One would be to set up a boolean field to indicate whether it has been displayed or not:
If you have multiple dialogs, you can put them in an array (of arrays) and nullify (or empty out) each dialog as they are used. Then use:
// add instance field
private boolean dialogShown;
// the 'if'
if ( ! dialogShown)
{
// second code-set above here
dialogShown = true;
}if (dialogs[dialogNumber] != null) // if nullifying by using 'dialogs[dialogNumber] = null;'
// or
if (dialogs[dialogNumber].length > 0) // if emptying by using 'dialogs[dialogNumber] = new String[] {};'thanks it worked but i have a question about animations this is my code but it stops at around image 3-4 im not sure which one..am i missing something?
thanks

}Are you releasing the "H" key? The animation will only run (as written) if the key is down. Once you release the key, the animation will stop regardless of which image it is currently on.
i just tested and it stops at image 4 every time and just for info i am not using it for the H key its just a test im gonna use it for when the bomb explodes and stuff like that ... i just wanna see the animation run first
thanks
You may want to show the rest of the code for that class -- as they problem is not apparent with what minimal code you gave.
i mean the rest of the class has nothing honestly but ok

Line 317 is setting the image to 'image1' and lines 318 and 319 will change it to 'image2'. As long as your actor can see water, its image will remain at 'image2'. Remove line 317, so you are not stuck at the same image. Next, you will probably need a way to indicate that the explosion sequence has started. Add a boolean field for that -- call it 'exploding'. Then your test method would look like this:
public void test()
{
if (exploding)
{ // continue sequence or stop
if (canSee(Water.class)) explosion(); else exploding = false;
}
else if (canSee(Water.class))
{ // start sequence
exploding = true;
setImage(image1);
}
