I've managed to get a gif image to act within the world when ran, but it's way too big. So how would I scale my gif image?

Use a for-each loop to iterate through the images to scale them all.

Making an actor face right or left

I am saying to store all 8 images. If not using an array, you may might want to use switch blocks to hash out which image to use (out of 4 for each block).

IllegalStateException: Actor not in world. An attempt was made to use the actor's location while it is not in the world. Either it has not yet been inserted, or it has been removed.

You could combine the addObject lines with the assignment lines before them (in most cases. That is, use the assigned values in place of what the variable the value is assigned to in the addObject line. As the pairs of lines for your labels are already quite long, I might leave them alone (or just put the String values in a variable and use it when creating the actor in the addObject line). A non-label example would be to combine lines 10 and 11 into the following: <Code Omitted>

If the mouse is clicked, place a new image

The getWorld method returns the value of the field: <Code Omitted>in the Actor class: <Code Omitted>The field is used to indicate what world, if any, the actor is in. While the actor is not in any world, its value will be set to null. Once you execute line 26, which removes the button from the world, the button loses its reference to the world it was in. So, it would be impossible to add an object into that world at that point. Either add the object into the world before removing the button or s

How do you add 1 point every time an actor touches instead of it rapidly adding points while it's already touching?

By Adrian2004, with 3 replies.
Last reply by danpost, over 6 years ago:

Add a field to contain a Point object and set it to any touching Point object. Also, set it to null if not touching any Point object. Only score if field does not contain the Point object it currently touches.

Need help with highscore system and a fix

By BalanZeD, with no replies.

Hey, I'm new to Greenfoot and need to finish my Game. I would like to add a highscore which is saved and everytime a new highscore is achieved the backround should be switched. that is all it should do and i really need your help. I have another problem in my scenario. I uploaded it and please check it out. I want to switch something. I want that the "Flappy2" in the "bg" subclass is flying faster than the "Flappy" in the Background subclass but it only works if i click reset and then new Background. But if I start this scenario the "Flappy" is flying faster than it should. Only the Flappy2 should fly faster in its world (bg) and I dont want to click reset and new Background everytime. I wanted to know if there is a solution. Thanks !
