Default Wind effects

Brian is the wind in your face and wind going away correct?
I thought that wind in your face lifted the pellet not push it down.

You need a better barrel on your rig...

Remember you enter a group size and ranging error... shots are just as likely to go up as they do down. The mathematical effect of a wind behind or in front is tiny. It's like moving the target back and forwards a few inches.

It's like shooting over water or over tarmac... unproven voodoo and negligible at best compared to the effects of grouping and ranging and cant even when the wobbly bit of the shooter is removed.

It's interesting actually - in theory if the wind is in your face then it's going to have the effect of slowing the pellet down which means it will land lower, and if it's behind you it will mean it gets there quicker so will land higher.

But when you think about it in terms of real numbers.. your pellet is coming out of your barrel at 500mph, a 5mph head or tail wind isn't going to make a noticeable difference.

It's the difference between your pellet doing 495mph or 505mph in a race to reach 55 yards. i.e. sod all difference.

The actual ballistic calculation isn't my invention, I'm just using the same one that Chairgun uses.

Something else you could also think about is - what if there's a very strong wind from the left or right - since the pellet is being blown off course in a sort of arc, it will travel further than one that went straight with no wind.

If it's travelling further then it will land lower... All that's true, but when you put it into perspective, the difference is so small you wouldn't notice it.

The likelihood is that it's a just a result of a pellet landing inside your average group (that just happens to be low) or the ranging error is kicking in.

That is kind of what the point of the game is though - if in real life you see a pellet land very low in the kill, don't always assume you got the range wrong or the wind was pushing it down etc. Other factors can come into play to make it look like that.

Brian that is a quality bit of coding there.Really well done!
I think it must be buggy though because I have missed quite a few

If you get a chance to do an HFT version it would be really appreciated I know.
Thanks again for this, such a lot of fun

I bet there are a lot of people here who will take issue with that from long experience. I certainly have done tests to see how much extra drop off I get when shooting rested prone at a known range with strong sideways wind.

Here's a thought Brian, you could have a training mode where after the shot it flicked up a line to show where a perfectly ranged shot would be, and also what your group circle is like in comparison to the target. So people could see what the effect of that was on the shot.

It would be nice to get cant in there as well...

Actually yes you may well see a slightly lower POI with a strong sideways wind - the amount is modelled in the game (although you can't aim high to compensate for it).

The game just uses the same calcs as Chairgun - that's the best I can do without someone giving me a better set of equations.

I haven't tried it, but have you checked Chairgun to see whether it says you'll get a lower poi in a strong cross wind?

I've got an idea to go someway towards that - the display of your potential poi zone might look a bit cluttered and confusing - I was thinking of displaying how much luck was involved in getting the shot and also use that value to weight the decision about whether you make a splitter or not
