ballistics | Calculate power factors for historic black powder data

So basically, I am working on this bullet optimization program. I wish to study how different ballistics parameters such as weight, length, and mass affect a ballistics coefficient. However, my training accuracy is 0, although there is loss and val_loss. I've read similar Stackoverflow posts regarding this, but none have helped me so far. Perhaps I just didn't do them right; I am referencing https://stackoverflow.com/a/63513872/12349188

Attempting to create tree view for a Ballistics Calculator I'm doing and get this error. 'type' object is not iterable for this section -> def create_tree_view_branch(self): I'm a novice so I'm sure I just haven't created it properly but this is the only issue so far that I've been struggling on for this long.

Can someone maybe help me with using lists in unity? I'm fairly new to them and currently im trying to implement a ballistics system in my game. Current setup is:

bullets' trajectory comparison

I'm a new python user. I'm using this powerful code to do scientific research and data analysis.

I'm writing my thesis in physics, I'm trying to describe and analyze the external ballistics behind the bullet flight.

I'm using matplotlib to draw graphics representing the bullet's parabolic path and the related cross points; given that I'd like to know if there is a special code to smooth up the graphic lines drawn following the real experimental data avoiding to have a graphic made by a lot of linear segments.

Thanks a lot to all of you!

I'm creating an RPG game web app and would like to store predetermined information about skills and traits. I.e. an array of objects defining things like "Battle-hardened gives +2 strength" and "Ruthless past gives -1 social".

I'm creating this using Express and NodeJS for my application, Mongoose & MongoDB for my database, and HTML as the front end. I am relatively new to this, so apologies if this is a simple question!

My initial thought was to create a Mongoose Schema for relevant attributes, i.e.:

I am working on a game, Hangman. I have the code down, I just want to display the word if you lose. How can I do that?

So I am trying to make a simple ballistics calculator for the game Arma 3 with python 2.7 and an excel file. The intent is to make a simple program that runs in the terminal that asks for the data involved in the shot you are trying to calculate, and output a value that is equal to the mil-dot hold over (the dots in a sniper scope) you need for a successful shot on target. The link with the example table will explain in detail what this involves. It is pretty simple.

It involves doing a trigonometric calculation to find the true, horizontal distance to the target. Then using that range in combination with a value (parsed? using xlrd) from an excel file that contains a variable used in the hold over calculation.

i.e. horizontal distance = range * cos(angle)

horizontal distance - zeroing = hold_over_variable_x ;

then use a table from this steam page to get another variable used in hold over calculation. In this example the M320 LRR rifle's table, which will be saved in an excel file. (I would like to add more rifles in the future, and use a raw_input variable to pick the corresponding excel sheet)

The zeroing will be a variable that is assigned through raw_input, and is needed to pull the correct value from said table.

e.g. zeroing = 1000

range = 1125

angle = 15.5

horizontal distance = 1125 cos(15.5) = 1100

horizontal distance - zeroing = 100 = hold_over_variable_x

hold_over_variable_y = -1.5 (parsed from excel file using zeroing variable)

hold_over = 100 * -1.5 = -150

hold_over would ideally print as -1.5.

I am doing ballistic calculations for a projectile. so in that I have a check box and based on check box I have to take the inputs i.e if check box is enabled then read values from double-spinbox and do ballistics calculations

else go by the default values of the double spin box for that I have written this code but I end up the error in setValue() so for my requirement wt method should I take.
