Here is that section in blue text converted to HyperNext. The part inside the FOR loop would go in your sprite movement section of the Animation event script.

Just place the script in a button and it will plot the trajectory on a canvas. I used a 300x380 canvas.

`Local angle,v,x,y,dx,dy,p,gravity`

CanvasClear(1,50,50,50)

@ initial conditions

Put 10 into x

Put 330 into y

Put -80 into angle

Put 8 into v

Put 0.1 into gravity

@ convert degrees to radians

Divide angle by 180

Multiply angle by PiFN

@ Calc initial x and y

Put CosFN(angle) into dx

Multiply dx by v

Put SinFN(angle) into dy

Multiply dy by v

@ Plot trajectory

CanvasSetColor(1,255,255,255)

for p=1 to 200

@ x

Add dx to x

@ y

Add dy to y

Add gravity to dy

CanvasPlot(1,x,y)
