Start a "set"-method | Start the scenario

Wow! Busch, your code was perfect, with all the comments I really understood what you did there for me. Didn't expect such a fast and great help here. Thank you :) Now the game works perfect. The only problem is, that it only runs one time and after resetting the scenario the objects don't move if I press the keys. But doesn't matter, it works when you start Greenfoot! Again: thank you and have a nice evening ^^

Source Code?

By g3o, with 8 replies.
Last reply by g3o, over 11 years ago:

Okay. Thanks everyone. I noticed this very thing that you guys are saying. That not everyone has "Open in Greenfoot" on their page. Which was the issue I was having. As I was just clicking one program to try and run it. After opening others, I noticed something that I had not seen before, which was what I missing here. It was just hard to figure out the one game I was trying to download and having not opened any others. Problem solved, thanks again guys.

How to solidify an object?

By BlazeGFX, with 2 replies.
Last reply by danpost, over 11 years ago:

See the documentation of the Actor class. It contains several collision detection methods as well as a couple ways to change the location of actors. You would ask 'if the player is moving downward and intersects a platform, adjust the vertical location of the player to stand on the platform'. Have the platform check for a player in such a position (and not moving upward) to move the player with the platform.
