The parabelfunc.py is used to calculate a ballistical curve with parameters for angle, speed, gravity to create a realistic flight. The parabelfunc.py is used to calculate a ballistical curve with parameters for angle, speed, gravity to create a realistic flight.
It is called 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) 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/weltrfaumgnietscies 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

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 singelchar 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.
