I am trying to have the player walk up to a certain point, press enter, and a text box will appear. I know how to do the text class and how to display the textDo I make the actor subclass for the text object?

That is my world for the text, I have an actor too called TextForTest which is where I am doing the text settings
I am a bit confused. I thought you wanted the player to go to a certain point before the text was displayed. It appears you have the text already displayed when the world is created. Maybe you can explain in detail, step by step, using references to the specific objects you are using, what is supposed to happen (as best as possible -- knowing that you are having a bit of an issue with it).
Actually, I do not even see a player being added to the world (looks like your title screen with a start button which has nothing to do with what you were asking help on).
I am working in a group which is why it is a bit fuzzy - Sorry!! So I made the text class so that I could show my group members how to do it. My next step is to have a player (Which the other member has created ) so I am adding onto another program. -- is to have the player approach the text box and press enter for it to appear
So I have a player I just am in the midst of going through the other program. I have to add onto it
Okay. I would not yet add the text actor into the world. However, I would create it and give it to another Actor object (whose class you will need to create). This object should detect the player and add the text into the world at the appropriate time (when touches player). So, in world, you might have this:
The TriggerText class would be something like this:
1 2 3 | TextForTest textActor = new TextForTest ("Pokemon");TriggerText trigger = new TriggerText(textActor);addObject(trigger, 286, 80); |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | import greenfoot.*;public class TriggerText extends Actor{ Actor toShowl; public TriggerText(Actor actor) { toShow = actor; // set image here or set a default image for the classs } public void act() { if ( toShow == null ) return; // no actor to show if ( toShow.getWorld() != null ) return; // actor already in world if ( ! isTouching(Player.class) ) return; // not touching player if ( ! Greenfoot.isKeyDown("enter") ) return; // 'enter' key not pressed getWorld().addObject(toShow, getX(), getY()); getWorld().removeObject(this); // optional }} |
Thank you so much! I am going to try it now.
Yes I caught that, thank you

This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { // (toShow.getWorld () !=null ) return; if (!

This is the trigger text, not sure why there is an error on lines 9 and 10. it says cannot find symbol
Let me get things straight, here. Apparently the whole background is to be occupied by this triggered text. But:
1) What exactly is the player to touch? that is, what is visible that the player is to move to before the text appears? and, is it part of the background image or an image set to an actor?
2) Is the text that is to appears permanent? or is it to change or be removed at some point?
3) If not permanent, then what about the thing the player touched to begin with? is it to be removed when the text is triggered?
Once these are answered, I should be able to provide some helpful tips.
OH! That makes sense - so I can remove the lines about the background.
okay, so The player is to touch a speech bubble or another character, press enter, and then the text box will appear.
The player then presses enter again and the text box will go away.
So the player will see the box, or see another character who is going to say something, press enter, text box with text in it appears, user reads it, and then presses enter for the text box to go away, and the player continues.
Sorry for all the confusion
