ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
I hope those are less fatal.
I can't help but think of the unfortunate timing of the sound of that bang and the receipt of the text message, that must have caused a lot of confusion. The sound was easy to dismiss as some random ship noise as they received the text after it occurred. If they...
It's a mighty expensive way to dump SSMEs into the ocean. It really doesn't have a viable mission right now, never did IMO. Starship is showing a predilection for blowing up before it can even get to LEO, and that is the basis for SpaceX's HLS. The SLS program has been cancelled after a...
This is from a BBC documentary that shows video of the Oceangate Titan support ship control room. The sound of the sub implosion is heard as a slamming sound on the deck of the ship:

I am on Firefox and can see @STS 's and other Xitter links fine, but they are blocked by default by Firefox and one needs to right click to allow them.
I only see text from @GLS. I think it is something on GLS's end on how they are posting the links, not a Firefox thing.
EDIT: I get this from...
Your interest in this project is important to us.
Thunder Chicken is currently not available to work on this project.
But please stay on the thread, and Thunder Chicken will get moving on the project as soon as possible.
You're flying backwards at a very high speed. The derivative_error is based on local y velocity assuming that you are nearly stationary laterally relative to the horizon and just want to control vertical airspeed.
You can try getting the y velocity coordinate in the horizontal reference frame...
You need to either use proper Lua string formatting or simply put in the single variable that you want to see the output for.
Lua syntax can be found on the internet if you look for it. That's how I figured it out.
You just type that in the main script in clbk_prestep or clbk_poststep and set the string equal to whatever you want to print out. No compiling needed. You then just fire up the scenario in Orbiter.
Can you post the Orbiter.log file when this occurs? The screen errors are not necessarily the originating errors, but something that failed because of another error. If you reload a scenario, sometimes if fails with spurious errors like this. Not sure exactly why this occurs, or if this is the...
Hmm, going off this image and estimating roughly 1 meter diameter and 500 kg mass, the mean density works out to be slightly less than the density of water or seawater. But it's not exactly spherical and my diameter estimate is probably not correct, so it is difficult to say whether it will...
Does anyone know the diameter of the lander pressure vessel, and if it was meant to be gas-tight on Venus? I am wondering if the density of the lander is low enough for it to float should it fall into the ocean. Terminal velocity is something like 160 mph, but the thing was designed to survive...
nil in Lua isn't the same as being equal to 0. nil means the variable is undefined.
If rpm is properly defined in C++ you don't need the if loop at all. The following will suffice:
rpm = rpm + 0.01*(rpm_comm-rpm)
rpm_comm is the commanded engine level. There is a following bit of code that lags the actual rpm:
if rpm ~= nil then
rpm = rpm + 0.01*(rpm_comm-rpm)
else
rpm = rpm_comm
end
You probably don't need to protect rpm from being nil.
It appears that you define the searchlight color in position 1 (and I'm not sure the vector notation is correct with the double brackets, but I am not so familiar with VECTOR3 in C++):
VECTOR3 searchlightcol[1] = { {1,1,1} };//white
but reference it in position 0...
Yep, that seems to be the issue.
When creating the animations, anything that goes into the parent-child chain of animations needs to have its state initialized to 0 for the reference vectors in the transformations to behave as expected. I suppose that makes sense, because the first...
One thing that I did discover is that the initial state of the animations does affect the behavior of even the parent-child animations. For example, if you define an animation like this:
anim_right_front_wheel_rotation = vi:create_animation(0)
This basically says that the item to be animated...
