4/18/2024 0 Comments Universe sandbox 2 save simulation![]() ![]() If a planet orbits a star in 8 days, and you set the time step to 1 day, it will only make 8 calculations every orbit. The time step is the time between every time the position of everything in the simulation is calculated. ehhh i can't explain it well, but just don't turn the speed up too high :) When you set the time step, to say, 50 years, it calculates the position of each body in 50 years and ignores if any big gravitatinal forces comes or goes. It'd take forever to do this in universe sandbox. Ok, when you have a system irl, every single body interacts with every single other body for every single point in time. Ok, the interface is probably changable, add that suggestion to the community idea list then Not sure what the repro steps are though, but possibly it's more likely to happen after having reloaded a simulation a lot of times. Sometimes it won't let me rename planets, or let me type letters into the box at top for selecting objects by name.Īt least once, I've tried to type an object into the center of universe box, and had it crash after hitting enter. If you want to "fine tune" try just typing in, which is what i always do for precise simulations and objectsįine tuning by repeatedly typing in new numbers is pretty tedious, especially when I'm not sure what I want exactly.Īlso, a lot of times it won't let me type numbers into a text field. The best you can do is get a better computer so that each time step can be calculated faster. There is no way to fix this, nor is it possible. ![]() This is because when you speed time up, the calculations become more inaccurate until the orbits become unstable and the particles fly away. Not sure about the first, just delete the old filesįor the second, it is physically impossible. The arrows could stay, but just have the usual spinner behaviour if you click and hold on the value while dragging up/down. Similar to the behaviour of "spinner" type parameters in most all applications. The current click on arrow and hold to increase or decrease is kind of cumbersome, especially when trying to fine tune a value, where I'd like to be able to move the mouse up quick for big changes, just a little for small changes, but if I'm not moving the mouse the value stays even while holding the mouse button. Lastly, could we get an option where clicking on a number to change it makes the value change when moving the mouse up/down while clicking. Which means that saving as a I work to make sure I don't lose anything if program or computer crashes creates a lot of files, and when I go to load, trying to figure which one I should load is tricky.Īlso, it seems that as I increase simulation speed, planetary rings fall apart, and if I make a sudden change in simulation speed they instantly fly away. The quick save icon at top left creates a new file that is always "My System" + date/time, and saving with file name doesn't start with the current simulations name, but if I type the same file name, it always add a number rather than saving over top. ![]() Is there a way to save my current simulation on top of itself? It seems that no matter how I save, it creates a new file. Universe Sandbox Legacy > Universe Sandbox Legacy | Help ![]()
