You can clean up the code in two important ways: firstly, use atan2 instead of atan like this angle# = ATan2(MouseY()-tankY, MouseX()-tankX) with that you can remove the "corrections" section :) secondly, always use cos with x and sin with y ;set shells mx value sh\mx = Cos(angle) ;set shells my value sh\my = Sin(angle) and ;Draw line for tank turret Line tankX,tankY,tankX+20*Cos(angle­),tankY+20*Sin(angle) I first learned programming this kind of stuff in blitz, good memories

@rck109d: thanks for the comments, I've included the changes in the source code download

what if you are using API where in drawing command you have only one place to put number of degree. example: al_draw_rotated_bitmap(*bitmap­, pos_x, pos_y, rotplace_x, rotplace_y, DEGREE, flag); ?

[amcadam26]

@MarkoLaizc which API do you mean? degree probab ly just wants a figure between 0 and 360. But not knowing which API this is I'm not sure

I see that you use CamStudio for your videos?

Can you make tutorial how to record HD videos with that so if you upload i will get same quality as your videos. And what codecs you use?

I tried CamStudio but never got HD out of it.

Do my eyes deceive me? Has amcadam started making videos again? For that I subscribe and take off my hat. On a more serious note, Thanks and welcome back. I always liked your videos man, hope you keep at it and good work.
