# Planetary Simulation iphone game

i need a planetary simulation game.

In this game users will control a spaceship or a planet to reach game level's target.

whole scene will be 2d space and masses [url removed, login to view] can be a planet, star, comet or a space ship.

users will control spaceship with its [url removed, login to view] ship will be affected by planets gravity but it controls itself with [url removed, login to view] uses fuel and it can consume [url removed, login to view] users have to use that fuel [url removed, login to view] a spaceship enters an orbit it doesnt need to be use [url removed, login to view] needs fuel when deorbiting a planet .So only entering or exiting from orbit need fuel.

This is standart [url removed, login to view] rule is simple you can find its formula on [url removed, login to view] will use very similar formula.

standart gravity says when 2 object have gravitational interaction. it is important how much distance between [url removed, login to view] interacts each other the square of the distance between [url removed, login to view] example let's think our moon affect earth for 100 unit for now from 350.000 km, if we put moon 175.000 km it affect earth 400 unit.

if we put 700.000 it affects 25 [url removed, login to view] distance is [url removed, login to view] in real so in our game.

-we will finish a gravity simulation that just work as in this link.

[url removed, login to view]

every object in here affect each other permanently, if you put too much object in scene that calculation slows even a quadcore [url removed, login to view] we wont put too much objects or we wont always calculate each object affect to each [url removed, login to view] we need an option [url removed, login to view] object will affect gravity force or not and this object will be affected by gravity force or [url removed, login to view] will be for each object in game so we will decide on or off [url removed, login to view] this options will be [url removed, login to view] we may close on 1st levels so that planets wont move only our space ship will fly through [url removed, login to view] next levels planets will move moons will orbit around an even them orbiting around a star.

our game must have an zoom [url removed, login to view] our whole scene will be very [url removed, login to view] will be able to zoom in and out like in angry [url removed, login to view] see whole [url removed, login to view] camera will follow spaceship [url removed, login to view] can focus planets if spaceship orbits it.

there are 2 option if user cant orbit a mass.

1- it cant orbit and it hit surface of mass then gameover.

2-there are 2 option for if user miss an orbit and goes away

2a-it misses orbit and goes away ver far away we say out of system and gameover to this.

2b-(preferred)user deorbits with its control and goes another orbit or [url removed, login to view] can goes away through near a planet without orbiting it and can reach its taget.

planets gravity helps him about speed or direction.

if user opens this assist option it will take less point.

hardcore gamers will have a lot of point without asist.

game will have gamecenter support so users will send their points to there.

path:

users space ship will have a path ,that path will show its histroy and future .

history is the path that have been passed (colored blue).future path is where it will [url removed, login to view] will be able to see their future if they dont do [url removed, login to view] they ll decide what to do(colored red)

if you follow the link i gave you can notice it has an option like path if you click it shows path but only history path.

also our path is fading both of them show only 3-4 sec history or future not more than this.

scores:

there are few things affects scores.

1-time: if you finish level less time you get more point,pointing is parabolic as in gravity force.

2-path: we give extra point to its path shorter path is more point.

3-assist option:if its open users get %25 of every point.

4-speed point if he hits faster to its target it get more point.

time:

time must be controllable in game user will control it to go slow or faster.

nobody without any reference plz ..

nobody more than budget plz..

if you dont have any reference you have to proove you ve finished a job like this.i will contact with your references,plz dont waste my time with fake names and lies.
