Re: Level 8

Good questions - Sean - the bullets were far and away the most difficult addition to the game. What, physically, *should* happen is so counter-intuitive that I had a hard time making sure the right thing *was* happening. For your specific questions, it looks like it boils down to Time. A couple leve...

Hey Creators

One of my favorite pieces of the forums has been getting to see what other folks are working on. So, inspired by JulieBodette's recent 'hello' - I thought I'd make sure there was a spot to share. If you've been working on something and are looking for feedback on a prototype, feel free to start a th...

Re: The 'Hello' Thread

Hey there, Julie - that's a pretty neat game you've got there! I love the idea of doing a classic tower defense game with microbiology. Definitely keep us updated as you iterate on it! On the off chance you haven't come across Immune Defense, you should check it out. It's a different take on a simil...

Re: Spaced Penguins clone?

Poked around and found the spaced penguins game you were mentioning.

Gravitational games are a big category. If you like that one, I'd suggest Gravitee, or any of the games in that series, I guess.

Re: Algorithm of gravity simulator

If you're using the full (downloadable) version of GSim, you can actually control which method of integration is used by opening the 'time' menu and setting the quality manually. The default, and the method used for the web version, is Runge-Kutta 4. There's no Barnes-Hut optimization, it's all poin...

Re: The List

I can't claim to understand I fully understand what's going on there, but I *did* finally figure out where to put the code.

(For those listening in at home: hit the params button to find the spot to put those in)

Re: How are you able to simulate objects passing through eachother without having them accelerate to infinity?

Getting a good simulation of gravity is a surprisingly complex topic — not something I realized when I started way back in the day. Some tips for your simulation: -First off, shrinking the timestep is always helpful. My simulation runs, as a baseline, about 40 ‘steps’ per frame, and 30 frames per se...

Re: I want to make a planetary system around a binary star system

Binary systems will be a bit tricky once you've got massive planets, too. As in, it's not uncommon for them to just break apart, at the scales we tend to work in for GSim. But the issue of the wandering binary can actually be solved easily by just hitting the 'center' button, which is in the menu in...
