Right, I have it almost flawless apart from the very bad edge cases of extreme speed and tight angles. Even then you can't see it anymore without pausing/screenshotting.

I am bad at math and don't know how to apply it, so I have just done what I can and bodged in magic constants everywhere (that ...

Yeah, Vector maths works.

Position is fine now, rotation not so much. It doesn't look nearly as bad and only really notice it if you pause/screenshot a very fast train.

Can't see a way to predict rotation as it looks like there's no info for what's next in regards to ...

I can get the speed, as in a total magnitude but not the velocity, as in the direction. In fact I see very little for direction. I guess I can use orientation and speed with vector math to get x/y components.

Though when the train is going fast they still look bad, hmm. It's like I'm setting the position for the last draw, so it's always lagging behind.

Even the rotation is wrong, hmm. It's like I'm getting the data at the start of the frame, applying that, then the train's ...

Ahhhh, I just found there's `LuaEntity.draw_data.position`, setting the `target` of my animation to that now:

Not perfect (and the renders are bad, just threw in random stuff I found on open source model sites to see if it was possible).

Thanks again - wouldn't have got ...

Fixed the wrong image by wrapping to keep the frame index in range. Just to tackle the position oddness now.

Thanks so much, that's made a big difference. The overlay texture is now rotated correctly.

I still have an offset issue, then a totally broken rotation if I reverse the wagon.

Not sure if this is to do with how I'm defining the animation - or how I'm setting the angle ...

I've just been messing with the `rendering` global. It doesn't quote work perfectly I find. I might be doing something wrong.

Compared to using the normal way of spriting a wagon, I'm using an animation and using the wagon's rotation to index the correct frame in the animation.

Only it drifts off ...

As it's on the Prototype, it doesn't look like you can modify it at runtime and even if you could, you would affect all instances.

I want to be able to show/hide Layers at the Entity level based on conditions. However, I can't see a way to do that via run time scripting. Is there anything I can do?

I was trying to think of all the mods that did this and rememebered some from my K2SE playthrough, then ruled it out as SE isn't 2.0 yet... Totally forgetting Immersite is from K2. Thank you, I will do just that.

After reading through all the prototypes around resources and map gen settings/autoplace settings, I can't see a way to make it only spawn one of the entity.

I want a fixed yield, with a fixed size and just one to appear anywhere the resource is "rolled". I can't see an easy way to do this. Is it ...

Solved it.

You have to ensure the path to your Factorio is set correctly, there's a "Factorio Version" at the bottom of your VS Code Window. Select that, set "Add another install location", then navigate to your Factorio path and find the executable. Then give it a name and save. Debug mode should ...

The documentation for FMTK mentions nothing on -how- to do it, as in set it up and get in to the debugger.

Hitting Debug in VS Code does nothing. There seems to be no way to set up what path to execute the game at. I feel like I'm missing something.

I'm brand new to modding in Factorio. I've only played the base game a little bit.

I was annoyed at the base game due to being able to just find ore so close by and run a new belt. Essentially making long term/distance logistics rather useless.

I'm looking at playing it as a cross between Factorio ...
