# Cowyeet

Throw the cow as far as you can!

![A cow with a parachute.](https://teapot.informationsanarchistik.de/Wobbl/Cowyeet/raw/branch/main/textures/cow_with%20parachute_.png)

Install the Modules with the following command:
```
pip install pynput
```

In versions after 1.0, it will require

The parabelfunc.py is used to calculate a ballistical curve with parameters for angle, speed, gravity to create a realistic flight.
It returns its coordinates depending on the resolution (xmax-xmin) * (ymax-ymin). So you probably want to keep xmin and ymin at 0.
0/0 is in mathematical representation left/down corner.

The function is called 
```
berechneflugbahn(cow, xmin, xmax, ymin, ymax, startwinkel, startgeschwindigkeit, starthoehe)
```

and returns a list of x and y coordinates: [x1,y1,x2,y2....] like the following example for a display with a width of 10 points/pixel/char/weltraumgnietschies starting with x=0 
```
[0, 0, 1, 1.1, 2, 1.7, 3, 2.4, 4, 2.9, 5, 3.5, 6, 4.0, 7, 4.5, 8, 5.0, 9, 5.4]
```

The parameter cow is not useless, it can be set to any singlebyte ASCII string like "*" or some doublespaced UTF8 char like "🐄". If it is a singlechar in ASCII, which is the default, the curve will be calculated with singlesteps, if ist is a UTF8-String, each step will be 2 points, because we now know, we have a textmode display and doublewidth chars.

```
 # X-Resolution of the display 

 cow="🐫"
 xmax = 100
 ymax = 40
 ymin = 0
 xmin = 0
 startwinkel = 34
 startgeschwindigkeit = 31
 starthoehe = 0

ergebnis = berechneflugbahn(cow, xmin, xmax, ymin, ymax, startwinkel, startgeschwindigkeit, starthoehe)

for count in range(xmin, len(ergebnis), 2):
    x, y = ergebnis[count], ergebnis[count + 1]
    curpos(x, y)
    print(cow, end="")
