Last reply by danpost, about 12 years ago:

By instance reference field, yes. However, you do not need a 'Score1' and a 'Score2' class; you just need a 'Score' class that you create two instance objects with: <Code Omitted>The 'get' methods will allow obj

World constructor

By wslade, with 4 replies.
Last reply by davmac, about 12 years ago:

It does compile

It couldn't possibly compile, for the reasons I gave above - the score_field variable is not accessible from the method in which you use it. Are you now talking about different code (perhaps the second variant that you posted originally)?

For some reason, I thought that a world didn't use an act method, because I had never seen one there.

Ok. You should read over the documentation for both the World and Actor classes in the API reference. You will see that they both have an "act" method. (Furthermore, you can put an "act" method in any class, though it will not have any special significance to Greenfoot unless it's in a World or Actor subclass).

Can u help me to update my health bar

By coder04, with 1 reply.
Replied to by danpost, about 12 years ago:

It looks like you are creating a healthbar for the laser, which is not the same healthbar that you have in your Ship class. Remove line 12 and change line 50 to: <Code Omitted>You should, however, refrain from using the same name of a class as a variable name. That is, you should use something like 'Actor ship;' instead of 'Actor Ship;'. I noticed that your 'life' field starts at zero and is decreased from there. It will never be checked and found to be zero (see lines 21 through 25) . Also after that (line 26),, you are using a method that requires the actor

Projectiles removing themselves

By ajmetal, with 3 replies.
Last reply by Super_Hippo, about 12 years ago:

The 'checkHit' method now returns a boolean. So if the Laser objects touches a SpaceFly, it will return true. Then, or if it is at an edge of the world (only top or bottom as it is right now), it will be removed from the world.

What will the following method do?

Replied to by danpost, about 12 years ago:

Yes -- since 'UrRobot' is the superclass of 'AugmentedRobot', that is exactly what it will do.

I have an error in my space class

By coder04, with 1 reply.
Replied to by danpost, about 12 years ago:

Apparently, you do not have a no-argument constructor for the Ship class and the constructor you do have required a Bar object reference be passed to it. Try changing line 96 to this: <Code Omitted>
