canon and bullet problem

[rustyNails]

hi,
im trying to build a shooting game and i have a question.
how can i get the effect of bullet emerging from the canon?
i used to code it as bullet_.x = canon._x and bullet_.y = canon._y so the bullet starts from the middle of the canon. if the canon moves in the meantimes it looks a bit odd.
how can i make the bullet starts from the end of the canon, no matter where canon is at the moment???
reg,

if you are only changing the x coords then you can use this.
taking the registry point on the canon to be the top left.
kepping the _y of the bullet the same.

bullet._x = canon._x+canon._width;

if the registry point of the canon is in the middle

bullet._x = canon._x+canon._width/2;


hope this helps

thanks mate, i'll try this...

well best way to do it would be to make the cannon registration point at the place you want the bullet to come out. and just use



bullet_.x = canon._x
bullet_.y = canon._y

[bombsledder]

bullet._x = canon._x
bullet._y = canon._y


you had a typo and you put the "." after the "_"
