Game Maker Studio Gravity Problems
- by Dusty
I've started messing around with Game Maker Studio. The problem I'm having is trying to get a gravity code for orbiting.
Here's how i did it in XNA
foreach (GravItem Item in StarSystem.ActiveItems.OfType<GravItem>())
{
if (this != Item)
{
Velocity += (10 * Vector2.Normalize(Item.Position - this.Position *
(this.Mass * Item.Mass) / (Vector2.DistanceSquared(this.Position,
Item.Position)) / (this.Mass));
}
}
Simple and works well, things or bit and everything is nice.
but in Game maker i don't have the luxury of Vector2's or a For-each loop to loop threw all the objects that have a
mass. I've tried a few different things but nothing seems to work
distance = distance_to_object(obj_moon);
//--Gravity
hspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass)
vspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass)
thanks for the help
