Generating Random Color and Brightness

By theDoctor, with 3 replies.
Last reply by DonaldDuck, over 14 years ago:

Just to add to this, you can assign an alpha value to your new color. The color constructor new color(float r, float g, float b, float a) does this. Greenfoot.getRandomNumber returns an int, but it should be converted to a float in the color constructor. If not, it's an easy fix. Change your color constructor to this. <Code Omitted>

I'm not sure what lead you to think that "Vector" would be renamed to "Explosion" - no, the classes have not been renamed. You can find the original SmoothMover and Vector classes in the asteroids scenario.

"Saving" the World

Replied to by Duta, over 14 years ago:

Yes - there are probably better methods, but I use the following (I haven't got any uploaded scenarios with multiple levels, but I've made a few) method: Once you're moving on to the next level (with the setWorld(new NextWorldName()) method), pass the objects to the next world in its constructor. In other words, you'd have it like this: setWorld(new NextWorldName(getObjects(null))) and then in the NextWorldName class, you'd obviously have to modify its code so that its constructor takes a java.util.List as a parameter, and then store it. Then, when you want to go back to the first world, you

Duplicating Actors?

Hey, I figured it out. Apparently that particular piece of code needed to be in the original "if" statement in order for it to work. I have no idea why that is seeing as my other buttons worked fine. Oh well.

Maybe because of what I said?

Scoreboard

By programmer22, with 19 replies.
Last reply by danpost, over 14 years ago:

You need to be a bit more specific. Where is your counter? How is it declared? Are you trying to get the score TO the scoreboard? Usually, the score is kept within the scoreboard class, and a reference to the scoreboard is kept in the world class. That way, methods such as getScore(), bumpCounter(int), and other counter related methods can be placed there and the act method will update the scoreboard image (if the score is in view the whole game-set).
