Working with Colors
Use:
(which you probably already have).
Do not use:
or anything similar.
import greenfoot.*;
import java.awt.Color;
import greenfoot.*;
Color(255;0;0);

if I just weite something like:
Color(255;0;0);
I corrected that, but it still doesn't accept the Code. I watched a tutorial About this, and there he wrote something like:
But if I run the Scenario, the line does not appear anywear on the screen...
(The World is 900 by 900)
public void act()
{
GreenfootImage draw = new GreenfootImage(100,100);
draw.setColor(Color.BLUE);
draw.drawLine(400,450,500,450);
setImage(draw);
} I red an discussion about a similar problem, and the line shows up by now. Still there is the Problem with the Color...
Your image has a width of 100 and a height of 100. Your line is outside the image and therefore not visible.
The Image is there, I can see a White line and ist doing what I want it to do, but it's White...
Again, you have an image which has the size 100/100. You have to draw inside this image (0..99 for x and y) if you want to see it. You draw from (400|450) to (500|450) which is outside the image.
Imagine you have a piece of paper lying on a desk. If you draw on the desk, then it won't be visible on the paper.
I know and I already fixed that...
Now i‘s drawing on the background.
But I cant change the color. I wachef an tutorial where he used something like this:
But when I tried this, it threw some errors back...
getWorld().setColo(Color.RED);
