Hello everyone. I am fairly new to Greenfoot and was wondering if anytime in the future Greenfoot will be able to program in 3D spaces rather than just 2D.

There are some 3D engines by now, you just have to search for it. But Greenfoot isn't made for running 3d games, so they are very laggy...

Nevermind! The problem was that world ref wasn't correct. It didn't point to the right world, which is Space.

Attempting to spawn actors on a timer

By HappyDragon78, with 1 reply.
Replied to by Super_Hippo, over 7 years ago:

"mainEnemy()" is a method, "mainEnemy" is a variable. In your case, you set "mainEnemy" to a "MainEnemy" object in the world. You want to spawn new actors though. So you can remove line 28 and change "mainEnemy()" in line 30 to "new MainEnemy()". You need to add a call to the method from the act method. I suggest to add the "enemySpawn" method into your world subclass instead, though.

I solved it, in my world subclass, at the end I had "setLocation" method called for. And I also changed the size of the world. Works great now, thanks for everything you did.

Overlay (HUD) in Scrolling World

By Syes, with 1 reply.
Replied to by danpost, over 7 years ago:

Hey, I´m using danpost ImageScrollWorld (https://www.greenfoot.org/scenarios/19020) to move my Player around . My Problem is that I want tow Actors (e.g. Health & Mana Bar) to be on screen and unaffected by the scrolling. I tried to create a subclass as "Overlay" of the ImageScrollWorld and place my Actors on that but that did not work for me. Can someone point me in the right direction?

Just place the following line in the Health and ManaBar classes: <Code Omitted>To effectively prevent them from being moved.

Timed Power Up Help

i want to make it so the speed only increases for 10 seconds rather than for the rest of the current instance.

Add a timer field. Set it to 800 or so when powerup is eaten. Separately, in act, if timer is greater than zero, decrease it and if, upon that, it becomes zero, reset the speed: <Code Omitted>
