Can anyone help with this one? I really cannot remember how it was done in teh first place
It's "python"
Ive got a compass on a screen thats HRES = 1920 VRES = 1080
and I've now changed the orientation of the screen to portrait mode and altered the resolution
so it's now 1080x1920
What I want to do is change the compass code below so the centre of the compass is higher to the top of the screen but I can't figure out how to set the position of X, Y, WID, and CX and CY so I can heep the horizontal centre of the compass but move the vertical centre higher
this is the code if anyone is able to help
def rotateTriangle(angle_deg, pointerRelPoints):
angle_rad = angle_deg*2*pi/360
res = []
for (x,y) in pointerRelPoints:
xrot = x*cos(angle_rad) - y*sin(angle_rad)
yrot = x*sin(angle_rad) + y*cos(angle_rad)
res.append((xrot,yrot))
return res

y = cy-1.1*wid*sin(pi/4)-ren.get_height()//2
screen.blit(ren, (x,y))

Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.
