I'm trying to write a space flight simulation game using realistic planetary distances. As a result a need to zoom out quite a bit, but AppGameKit seems to cap the zoom to 0.001, is there any reason for this?

I personally had a few issues zooming out over a certain value. For example 3D just stopped rendering at one point. Perhaps TGC introduced this cap to stop this bug from happening?

hmm, as workaround you can scale sprites and scale position from
original pos.
also i think u need a unit 1.0=1000.0 km or something

Ah well, I'll just have to work around it.

I'm using a scale of 1px = 1000 km but I'm also having to fudge the physics as floats are not precise enough to model real orbits.

i know from someone, planets rotate by formula.
i believe its same a electric oscillating circuit.
u have some input values and get output values.
means u do not need physics.

I understand that and I'm applying the Keplarian equations to the planets and moons, but the player's spacecraft can change its velocity when the player fires the thrusters and this changes the orbit. I do need some simple physics for this.

I can calculate the new orbit based on position and velocity vectors, but I was hoping I could cheat and just time step the orbit based on the current velocity vector. My fudge is to implement the complicated orbit calculation and reposition the player based on this.
