Holy cow! You registered at least 13 different accounts! You officially hold the all-time record for any one person attempting to register accounts on Algobox! They were all previously banned and so you cannot log-in to them even if you used the correct password. So, no worries about that. Just please don't do that again.
Concerning asking permission to use other's scenes, we understand that many people no longer use Algobox to share scenes and so you cannot contact them to ask permission. We generally tell people who want to copy a scene or a part of a scene from people who no longer use Algobox to go ahead and copy what you want. Besides, it's nearly impossible to prove who owns what because so many people copy so many scenes and then modify them and upload them as their own. Then those copied scenes may get copied by another person! So, as the Admin, I cannot waste my time trying to track down who the original author of a scene was.
People should keep one thing in mind: Everything that gets uploaded to Algobox becomes the property of Algoryx which is the company that owns this website. So, Algoryx makes the rules, not the people who use the website.
Just a couple of suggestions: Whenever you upload a game, you should specify what the controls are (mouse? keyboard keys?). If you want to be seen as a real pro, you should also briefly explain what the game is about and what the player must do to win. You should also explain things that will cause the player to lose (or die).
whatvaheck -- That's because the objects are on a different layer than layer-0 which is the default layer. Right click on the background and then hover your cursor down to layers. When the layers window opens, select layer 1 by right clicking on the text (the text will turn red). DO NOT CLICK THE RED X! With layer 1 selected you will then be able to select objects in the scene.
Why do you upload a scene that's not finished and you tell people not to play it? Wouldn't it be better to wait until the scene is finished before uploading it to Algobox?
It runs faster when I give those yellow circles a negative attraction (-1000.0). But if I increase it much higher, then the device fails when the white balls start to scatter from too much force.
