Issue with removing object.

By gdwd4, with 1 reply.
Replied to by Super_Hippo, about 11 years ago:

There is a difference between 'class' and 'object'. An object is an instance of a class. In the code at the bottom, you create an object of class 'Back' and so on. If you click an (or the) object of the class 'RedTile', you try to remove the 'objects' which you created below. You can not say "remove this class". To delete an object, you need a reference to it or you can delete every instance of the class. This probably solves the problem, too, if you don't need to separate between different e.g. BlueTiles in your world. So either use this

How to add text

Replied to by danpost, about 11 years ago:

There are several ways: (1) use 'getBackground().drawString("xxxxxx", 20, 30);'; you may have to change the drawing color of the background image before drawing the string; also, you may want to alter the drawing Font (2) create a text GreenfootImage using the constructor that requires a string and then use 'getBackground().drawImage(textImage, 20, 10);' to add it to the background image (3) create a text GreenfootImage as in (2) above and set it to be the image of an actor and add the actor into the world The easiest to remove and the simplest to use is (3). If you have a flat backgrou

in the constructor for key, pass in a String that is either "black" or "white". have the keys set their images using this String. if you do this the rest should sort of fall in place a bit easier. here's something that you could use: public key( string label, (...anything else you/they have) ) { if ( label == "black" ) setImage( the black image); if ( label == "white" ) setImage( the white image ); // anything else. } if it is the key the key is linked to is pressed, it will use the same type of thing: if ( Greenfoot.isKeyDown( key ) { if ( l

Need Some Help With Variables and Actors

By bluefoot135, with 1 reply.
Replied to by danpost, about 11 years ago:

For you first problem, refer to the java tutorial page on Objects (the second section is on declaring a variable to refer to an object. For you second problem, the page on 'this' keyword is what you need to refer to. It would be best to remove the 'other' object before removing 'this' object from the world.

Can greenfoot run under JDK 1.8?

By rothmanw, with 2 replies.
Last reply by rothmanw, about 11 years ago:

Thanks davmac. Within the same server space there are learners taking pure Java with Netbeans IDE - so yes Netbeans is running as well. I think the technologist who installed Greenfoot read about the 1.6 JDK and rolled that out as well instead of just installing pure Greenfoot. I noticed on this Greenfoot site that 1.6 is the standard, but then I also saw comments that 1.8 runs fine. So given that I assume that it is NOT the versions that play a role (unless having two JDK 1.6 and 1.8 ?), but the RDP and memory allocations. Thus my question now is, are there environments running RDP and
