Planets won’t render when using for-loop in libgdx
I am running an N-body simulation (testing with three planets at first) and it appears when I use a for-loop to do so, all of the planets don’t render and while debugging i found out they don’t even have an address. However, if I manually type in the movement of all three planets it works. Here…
Orbit Simulator in Java returning odd values for velocity etc. despite correct math
I am using LibGDX to make an orbit simulator (elliptical as planets possess their own initial velocity) and I have the physics mapped out like so: The problem is that my planet wobbles around and doesn’t orbit at all. I fear my calculations in the code might be wrong as the physics are definitely double…

Box2D Fixture doesn’t get the same category and mask bits of its FixtureDef
This is quite bizarre in my opinion. I create fixtures based on a fixtureDef. I use the libGDX version of Box2D. This is my code: The output of this code is: WHAT? How can the filtering bits of my fixture not be the same of the fixtureDef they were created with? I have also found this out: The mask that
LIBGdx – I get gray pixels in a sprite when saving as PNG
I’ve been trying to scale down a sprite and save it to the android local store for later use, but everything I’ve tried always results in a grey edge around the sprite. Sprites As you can see, the sprite batch blend function is set to GL20.GL_ONE, GL20.GL_ONE_MINUS_SRC_ALPHA and rendering to the s…
