There are different options for what happens when a particle hits the edge of the screen. Stop - The particle loses it's velocity from the direction it hit the screen. Bounce - The particle's velocity from the direction it hit the screen is reversed and it bounces off the edge. Continuous - The particle continues outside the screen and follows along the same path it would have, possibly reentering the screen. Multiply - The particle behaves like Bounce, but has a second particle created that Bounces in the opposite direction. (This can lead to many particles quickly which (Because of all the Math and Physics involved) can cause considerable lag. I put it in because it can give some cool effects if done right. I usually use few particles on very low gravity.)
Other features are Center Objects which will not be affected by the gravitational force of other objects on the screen, but will still act on the other objects. The two center objects are Sun and Black Hole. Each of their gravitational forces can be set individually, but only one Center Object can be on the screen at a time.
My favorite setting is the grid setting. It allows you to automatically place particles in symmetrical grids. You choose the rows and columns for the grid and hit add. For this one, something cool is to create a grid with all the particles having zero gravitational force, and have a center object with just a little.
One of my current plans for this are to create an option Tails sets an amount of smaller particles that appear in the last few positions of particles. (This has been added in version 1.14 :) )
Another is to create different settings for placing shapes of particles on the screen. Some examples would be a rectangle of particles, a circle, or a star. If there is something you would like in this app, then leave a comment. Who knows what could appear in the next update. :)
Also, the internet permissions is needed to load ads. Maybe this poor college student can make a buck or two from his hobby. :)
And when be convinced that your accelerometer everything is all right, can enjoy rolling balls on the screen using gravity.
Touch you screen to create new ball and rotate your device to accelerate them.
Balls have random color, mass and radius.
Сollisions of balls occur according to physics laws.
Using orientation sensor if accelerometer unavailable.
Make your friends believe that your smartphone's screen is cracked.
How to use:
Start "Crack Screen" and hand your phone to one of your friends. Wait until they touch the screen. Thats when they'll hear a loud cracking noise and notice the "Crack screen" on your phone. Now you can start to blame them for breaking your phone, maybe they'll buy you a new one.
Shock your friends with realistic looking screen injuries and nerve wrecking cracking sounds.
Click to the menu To set the Crack Screen Set As a Wallpaper.
* Sound effects to accompany all the cracks.
* HD cracks images to make the effect look real.
* Set the crack Screen as a wallpaper.
Crack screen is even applied to the lock screen and home wallpaper.
How to Use:
Click on 'start' button and your screen will appear cracked.
To stop - click on application icon and then 'stop'.
This is the best prank app because after phone screen is cracked, you can still use your phone with full functionality, cracked screen or broken display image will be on the top of all your applications until you exit. Crack screen is even applied to the lock screen and home wallpaper.
- Use app with cracks on the phone screen
- Different screens to choose from
- Sound effects to accompany all the cracks.
