Make actor dissappear after getting touched by enemy
By janaaa, with no replies.
So in my program my main actor is maxwell. I want the game to end when my main actor is touched by the enemy catwalk. I normally know how to do this and I have used a code for a similiar thing before. <Code Omitted> So I used this to make the enemy dissappear after being hit by a bullet and it works perfectly fine so I wanted to use this for the problem above too. It looks like this: <Code Omitted> But for some reason nothing happens. I´ve tried different things and tried to find other solutions but it never works. So I would really appreciate the help :D

Delay a method on a single actor

im trying to delay a method on a actor so the actor should walk over a route but not to quickly can someone help me with developing a delay that is like 500 milli seconds long but only goes delays the next action this is the code: << Code Omitted >> this is a part of the code in reality its much longer but how do I program now a delay that makes him delay before the next action?
I think you misunderstand the way greenfoot works. The
method is being called by greenfoot repeatedly at a regular rate (usually around 50 to 60 times a second). The rate has a "
How to draw integers
By Deepfist, with 1 reply.
Replied to by danpost, 4 days ago:
I have a player actor who has multiple integer values, such as the amount of medkits, the amount of multishots left, the amount of bullets left in a specific magazine, the remaining speedUp time and the score. These integers work fine, but I am not sure how to show them on screen with their right amount. These integers are in the player.class, but their values are changed by different actors; so when you pick up a medkit then the medkit.class will add 1 medkit to the count, not the player.class itself (this is done with a getOneIntersectingObject code, not sure if that's import
How to Make Drawing Game

Can we make a drawing application with greenfoot? For Example, if we want to make a program to draw letters of the alphabet for students. If it's possible, please show me how the algorithm is?
Of course, it is possible. However, what you need to do is attempt to do it yourself. Then, if you have issues, post what you had tried and explain how it is not what you want. Since you will be dealing with images, you should familiarize yourself with the
class. Look over what constructors and methods are provided in the class.
Changing the order of subclasses of World (or Actor)
By doctorbeep, with 1 reply.
Replied to by Deepfist, 4 days ago:
I am not sure if there is an option for choosing the order, but I do (kinda) know how the order is decided It depends on the word/character. If you have a subclass that starts with an A and a subclass that starts with a B, then the A will be the top one. If you have a subclass that starts with an a and a sublclass that starts with a B, then the B will be the top one. Not sure why but it's like that. If you have Level 1 and Level 2, then the top one should be Level 1, unless your Level 1 starts with a small L, then it will be Level 2 Say you have Level Start and Level end, then Level End

I have a program where I want a character, lets say a male fish, interacts with a female fish and I want them to spawn another fish (either male or female, it doesnt really matter). I am new to programming and I can't find a solution to this problem. Can I get some help?
objects have a "

and female =

it returns as getobjects is always equaling zero and never changes the string variable
It does set a
