set image random??
Could you be a bit more specified?
Randomly take one image out of some or take a random color / random pixel for the image?
No one can help you if you just use such a sentence.
I want to make a random object (from random class) in the first run.
It's like I have banana class, apple class, grape class and I want one of three class showed up (random) in the first run.
In your first post, you wanted to make an image random. Now you want to create a random class.
For your second question, you can write something like this in the code in your world class where you create the classes:
(Of course you need to change x and y to the numbers you want.)
For the first question, you can just create for example a fruit class:
And then, in this Fruit class, you set the image to one the fruits. This is useful if all these fruits are the same in your game except their images:
1 2 3 4 5 6 | switch( Greenfoot.getRandomNumber(3) ){ case 0: addObject(new Banana(), x, y); break; case 1: addObject(new Apple(), x, y); break; case 2: addObject(new Grape(), x, y); break;} |
1 | addObject(new Fruit(), x, y); |
I forgot the other code - BB-code....
1 2 3 4 5 6 7 8 9 | public Fruit() { switch( Greenfoot.getRandomNumber(3) ) { case 0: setImage("banana.png"); break; //or whatever your image files are named case 1: setImage("apple.png"); break; case 2: setImage("grape.png"); break; } } |
