Hi, I want to create a circle filled with a color but make it transparent. Also, I want to create two lines from he center of the circle to the topmost point? How do I do this?

Create transparent circle
So you want to draw a circle, but that circle shouldn't be visible?
Or do you want a circle where you only see the border?
Two lines from the center to the topmost point: Well, drawing one is fine, but drawing another one at the same position will still look like it would only be one.
I don't actually want the circle to be transparent anymore. but the code for drawing a circle isn't working.
this is what i have:
public test()
{
GreenfootImage img = new GreenfootImage(75, 75);
img.setColor(green);
img.drawOval(0,0,75,75);
img.fillOval(0,0,75,75);
}
this is my constructor by the way.
Also, im going to be moving one of the lines so i do need two lines. How would i draw that?
Change 'green' to Color.GREEN' and remove the 'drawOval' line.
You may also want to use the image.
Moving lines on an image is not working. Then you need actors displaying the lines and let them move.
setImage(img);
Thanks. The circle now appears but how do I draw a line from the circle's midpoint to its topmost point?
img.drawLine(img.getWidth()/2, 0, img.getWidth()/2, img.getHeight()/2);
How do I check if the line is being drawn or not? I tried to increase the length of the line so I can check bu no line appears.
The line should be there, but you have to make sure that it's a different color than the circle.
The above code should draw a green circle with a diameter of 75 and a red line being/showing the radius.
public Test()
{
GreenfootImage img = new GreenfootImage(75, 75);
img.setColor(Color.GREEN);
img.fillOval(0, 0, 75, 75);
img.setColor(Color.RED);
img.drawLine(img.getWidth() / 2, img.getHeight() / 2, img.getWidth() / 2, 0); // I changed the coordinates around because you (ironphoenix20)...
// ...said "draw a line from the circle's midpoint to its topmost point"
setImage(img);
}Thanks. It works now.
