    can i move an image in libgdx to direction in angle??

    like i have a car an i want it to move it straight forwoard now if i change the angle of the image it should go forwoard on this direction...

    like in the picture..


    is it possible? i want to draw the image in a specific angle and i would like to move it forwoard on this angle...

    Batch.DrawRegion3(ballFrames(0,ballint) ,ball.x,ball.y,ball.w/2,ball.h/2,ball.w,ball.h,1,1,15)

    does anyone know how to calculate the new x y depend on the angle?

    maybe sinus cosinus??

    I don't think there is any calculation that needs to be done, libGDX does this for you automatically, all you have to do is give it the angle value.
    I'd have to think back, i've done this before but haven't used libGDX in such a while i'd have to dig some of my unfinished old projects.

    One thing you can do is use the SCN2d class, this makes things a lot simpler.

    it would be great if you could find a simple example for me (in your old unfinished projects) that show how i can do it... thanks :)

    I know. And B4A would not be the same without him, hat down and millions of thanks from me. In my opinion, he should be awarded in some way...

    Yes, Steering Behaviors is what I use myself to move sprites.

    Yes, i totally forgot about this library, yes you can definitely use steering behaviors for what you want to achieve, and it would make things way easier too.

    Good Luck!

    You should place an @ in front of user names so that they receive an alert and are made aware of your post. That way @Informatix will see your post and know how valued a member he is :D
