BIG update! - Big optimization allowing for much higher particle counts - Reduced initial planet wobble - New shapes: cube, wall and disk alongside spheres - Indestructible bodies: shapes keep their shape no matter what - Improved Compute and Replay, you can now record much longer and more stable - Many new planet textures - Save and load setups, with thumbnails - Black hole fix + added accretion disk, rings fix - Shadows: real-time shadows with three quality levels (Off / Basic / Advanced). Advanced cast and receive shadows per particle. - GPU rendering: planets now have correct depth and occlusion

Very good app! But….

tbh I recommend this app a lot lol its really fun and possibly even addicting! Maybe add a ability to add more stars in Protoplanetary disc so you can see what’s protoplanetry disc merger looks like but add the ability to to change the stars colours! (Green. Blue. White. Red. Purple.) and make it so you can spawb a lot! (Max: 8) I hope you add this but it’s fine if you don’t want to!

Uhh, think you went full-on god mode 😭

Best thing ever, like, it’s literally space sim or whatever it was but for mobile and for free. Currently the best game on my iPad. All I need is Solar system sim thing you made and then my iPad will be like: “I’m the best device in the house😭😭😭😭😭😭😭😭😭😭. bruh.” TYSM FOR MAKING THIS FREE!!!!!!!!!!!!!!!!!!!!!!!!!!!

FAQ

What is Space Crash Simulator?

Space Crash Simulator is a mobile application that uses Smoothed Particle Hydrodynamics (SPH) to simulate planetary collisions in real time. It allows users to witness and create detailed, physics-based cosmic events.

What are the key features of this app?

Key features include a robust SPH simulation engine for realistic planet collisions, a Setup Mode for customizing initial conditions like particle count and velocity, and adjustable settings to optimize performance on various devices.

Is Space Crash Simulator free to download?

Yes, the app is free to download and offers in-app purchases. It also includes advertisements.

Can I adjust the simulation settings?

Yes, you can customize initial conditions in Setup Mode. This includes adjusting parameters such as particle count, planet velocity, and collision accuracy to create your own unique collision scenarios.

What kind of devices can run this simulation?

The app is designed to be accessible on a range of devices. Settings like particle count, accuracy, and timescale can be adjusted to allow even less powerful devices to run the simulation effectively.
