    We aren't communicating.

    Maybe try to find a forum in your native language.

    Code:
    `o=            *
    Gun, star. You've just drawn them both.
    Code:
    `o=           *
    Gun, star. You've just drawn them both.
    Code:
    `o=          *
    Gun, star. You've just drawn them both.
    Code:
    `o=<       *
    Gun firing, star. You've just drawn them both.
    Code:
    `o= >     *
    Gun, bullet, star. You've just drawn them all.
    Code:
    `o=  >   *
    Gun, bullet, star. You've just drawn them all.
    Code:
    `o=   > *
    Gun, bullet, star. You've just drawn them all.
    Code:
    `o=    >*
    Gun, bullet, star. You've just drawn them all.
    Code:
    `o=    X
    Gun, explosion. You've just drawn them both.
    Code:
    `o=
    Gun. That's all you draw.

    It's nothing to do with SDL, it's purely your internal data.
    Eg.
    Code:
    if ( bullet.x != star.x && bullet.y != star.y ) {
      // drawSomethingUsingSDL
    } else {
      // some other stuff
    }
    The decision to draw (or not) is not dependent on the thing you actually use to do the drawing.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
