i do not now how to make it

You will use basically the same format for jumping as for firing a bullet, tracking the state of the jumping key. You will also need to retain the horizontal direction that the jump is initiated at:

You will never fire a bullet with the current code because you are guaranteed to use getKey method previously in either the if (!onGround) or its else part. Each time the method is called, it will return a new key or, if no key remains in the keyboard buffer, null. Also, with Greenfoot, the buffer is loaded at the beginning of each act cycle while the scenario is running, meaning that if you use the getKey method multiple times, only the one first acted on will be guaranteed to get any key. For player controlling, better is to use the isKeyDown

Hi, i have build a game just like doodlejump. You are moving upwards in a world which is 10000 pixels high, but you have to scroll manually with your mouse to keep the camera on the player. Can I move the camera or just simulate that I use the scrollwheel on the mouse? Thx in advance xtay

Please refer to my Scrolling Tutorial scenario.

If your code above is in the Wombat class, then use this instead of Wombat.

I am trying to make a basic movement system but my if statements will not work for some reason I can only get one of the iskeydown statements running at a time << Code Omitted >>

As is, your else part will execute regardless of the state of the D key (since else is linked only to the A key part). Move line 12 to the beginning of the method and then instead of else, just ask if it is still false at line 11.

Problems using Counter in Text Actor

Last reply by danpost, about 8 years ago:

The same can be said for the Good component field. That is, the line: <Code Omitted>would need to read <Code Omitted>for the field to obtain a value and for the getGood method to return that object (and not null).

You start with a World object and some Actor objects. What have you tried? (your question does not conform to site standards -- not specific enough and no code given).

Send numbers of one array between two classes

By DanielG99, with 1 reply.
Replied to by danpost, about 8 years ago:

You can use a "getter" and a "setter" method in the class where the array is located. Like the following (presuming the array holds int values): <Code Omitted>Then in Class_B. you could use something like: <Code Omitted>

How to view documentation

Good question. The required HTML-Files come with the download. However, the program doesn't seem to find it. In the title it says "null" and you get an error when trying to open it in a browser telling you that the requested file can't be found. Unfortunately, I didn't find a way to make them appear by clicking on Actor/World. Seems to be a bug in 3.5.0. You can also find the Greenfoot API here: https://www.greenfoot.org/files/javadoc/
