EVE:WORLD is a free project that takes advantage of the Outerra engine's 1:1 scale to bring you a planetary invasion simulator set in the EVE universe. Asking CCP for permission was the first thing we did and we have full permission to use their assets. See the FAQ for details.Your fleet starts in space, close to Earth. Between you and the planet is the enemy fleet. You must strike at targets on Earth whilst being ever mindful of the environmental effects of gravity and atmospheric re-entry. Compensate your turrets as your artillery shells curve off-course the closer you get to Earth. Use smaller ships to make a controlled descent and attack targets directly. Beware, your capital ships were never designed to make planetfall. Even if their armour saves them from burning up you are then left with a 100,000 tonne brick travelling towards solid rock at Mach 5.
In between engine updates I have started work on basic path-finding for the AI. It can get a little frustrating juggling vectors in 3D but I have already created an auto-targeting function for ship turrets.
I'm also close to finishing the waypointing AI ships will use to travel between destinations. It works much the same as the turret function except it treats Earth as the "ship" and the ship as a turret mounted on its surface. I'm sketching out an AI Overseer function for controlling battles. This function will compile a database of all ships in the current session, their positions, their relative distances between each other, their health in terms of how many salvos from each ship it would take to destroy them, etc so that ships can decide who best to attack first or, if necessary, flee.
