I just did a simple code with the keys Left and right that makes the same move but in the opposite direction Move(-8) turn(-4) and Move (8) turn(4) I really don't have anything to start with so i'm sorry , any advice would help

Did you try this? What was your attempted codes?

Notes about the list: (1) The default value for boolean fields is false, so it is not required to add "= false" to line 11; (2) This may not be necessary if the objects created are equivalent each time. This will become apparent after moving on to (3) below; (3) The state of being "open" can be determined by a simple check, without the use of a boolean field. Note the code below:

Please clarify: * tile based: how is your world created? please provide the super constructor call line in your world constructor; if the third value is 1, then please explain what you mean by tile based. * moving multiple tiles at a time: does this mean skipping over some

Cannot fix unseen codes. Please provide what you tried in your world class.

The Actor class has a method to list objects within some radius of an actor. Take a look: Actor class documentation

thanks Spock47 then it works of course I make modifications to adapt the code to greenfoot I knew it was a color problem as bufferedimage does not work on greenfoot but hey you have to find the right code but I never thought of awtColor I tried with awt image bufferedimage - awtgetImage I don't even know if we can do that I didn't succeed, anyway thank you again Spock47, a new STAR TREK film in preparation or not??? I'm kidding, don't be offended

Basically, after moving, if an obstacle is touched, then move back. For example, after line 36, which moves Mario horizontally: <Code Omitted>} A bit more is involved when moving vertically when gravity is in play. See what you can do with it.

Maybe the code in this scenario might help: Jump and Run Demo w/Moving Platform

OK this is a hex code for 3 RGB colors and hsl are percentages of hue clarity, saturation and lightness and the color blue in hsb is h / 255, s / 255, b /255 cad (0.9f,0.5f,0.8f) approximately. I'm coming back to HSL, so it's for a color too??? I get lost a little Thanks for your help

First of all thank you for the pendulum code that's what I feared, a pendulum is moving, it's not good, it's more difficult to handle, i.e. changing size while moving... that's what I said to myself when I compared your scaling world demo scenario which is stable and a moving pendulum otherwise I thank you again

If you shared the source code when you uploaded it, then you can download it publicly from the site. If you didn't share the source code, then you didn't share it with us, so we don't have it either. You'd have to work out the details but the only alternative I can think of is to grab the JAR and decompile it. If you go to the legacy version of the scenario, e.g. https://www.greenfoot.org/scenarios/18225?js=false then you can search the page source for "<applet" and find the path to the JAR then download it. That at least has

Hi, the external library is not exported. (Referring to your game as "game-jar" and to the external library as "external-jar") When you open your game-jar and view the content of it, you can actually see that your external library is missing. There are two ways (i know of) to fix this: 1. You could extract your external-jar and add the extracted folder(s) to your game-jar exported by Greenfoot. The command prompt to run your jar-file is the same as shown in Greenfoot when exporting it (because now it is actually contained within game-jar). 2. When running your game-jar via command
