Small correction, since the vec.erase returns the next valid iterator, you probably don't want to increment it again with the ++it when you reach the end of the body.

Erasing the last element in this case would crash the program.

Probably want to move the ++it to an else block.

I dont understand, can you fill?

for(tir& t : tirs)
    for(alien& a : aliens)
        if(t.x>a.x && t.x<a.x+60 && t.y>a.y && t.y<a.y+60)
"Erase the aliens shots"
