what part of this are you struggling with
#I need help
quaint oasis
signal hedge
i dont know how to code that
frank roost
So you want the look_at() function to get your player to look in the direction of your mouse in 2d space
quaint oasis
for this youll need the position of the mouse, which you can get from Input, try checking the docs for that
you can get the direction between two vectors by doing mouse_position - player_position
frank roost
And when you click or whatever, spawn a bullet projectile into the scene (or if you want hit scan, instead send a ray cast and add vfx later)
signal hedge
how can i make the gun point to the mouse???
frank roost
Look_at() function
signal hedge
yeah but like how can it look at the pointer
serene lark
Yep. You will want to have your nodes probably setup like this:
Player -> GunHolder -> GunSprite
Then you have the GunSprite offset to look like the character is holding the gun properly. Finally, you make the Holder node look_at the mouse position 🙂 you will need to investigate the gun sprite a bit more tho (I’ll leave that for you to find out)
quaint oasis
the look_at() function, as mentioned above
frank roost
Let me pull up the doc
signal hedge
if i put the look_at() does it point to the mouse?
serene lark
On the player, in your player script, you can get the current mouse position
You give that to that func
quaint oasis
you have to tell it what to look at, its a parameter
signal hedge
you have to tell it what to look at, its a parameter
yeah thats what im asking what do i put in the ()
quaint oasis
so like, look_at(mouse_position)
signal hedge
oh ok thx
frank roost
if i put the look_at() does it point to the mouse?
Here’s the documentation https://docs.godotengine.org/en/stable/tutorials/2d/2d_movement.html
To get the Vector2 position of the mouse, use get_global_mouse_position()
quaint oasis
_process works
quaint oasis
no problem, best of luck :)
quaint oasis
if youre in a script thats attached to the player node, its just position, or self.position
signal hedge
im not
frank roost
Otherwise you need a reference to the player object
quaint oasis
what is your script attached to
frank roost
And then access the global_position field
signal hedge
the gun node
quaint oasis
is your gun node a child of your player?
signal hedge
no
frank roost
You can just make the gun a child of player so it follows the player
signal hedge
ok
quaint oasis
then if you do that i would recommend putting a script on the player, rather than the gun
signal hedge
i get this error
quaint oasis
when you do position + 18, what is your goal?
signal hedge
offset it by 18
quaint oasis
in what direction
signal hedge
the direction of the mouse
quaint oasis
hmmm
others can correct me if im wrong, but you might be able to just move it in the positive X direction, since it is already rotated towards the mouse?
signal hedge
yeah thats what im tryna do
quaint oasis
for which you can do self.global_position.x += 18
signal hedge
oh ok
frank roost
i get this error
The issue is you can only add a vector2 value with another vector2 value
quaint oasis
for which you can do `self.global_position.x += 18`
if you do this every frame though, your gun will "run away" so to speak
signal hedge
for which you can do `self.global_position.x += 18`
k i changed it to this now tho so i dont get the error
oh ok
quaint oasis
youll need to have it do that offset based on some anchor position
like the player's position
frank roost
I personally would just offset the gun relative to the player in the editor instead of code to avoid any hassle
quaint oasis
yeah, agreed
signal hedge
yeah
quaint oasis
Yep. You will want to have your nodes probably setup like this:
Player -> GunHo...
definitely recommend this setup
signal hedge
This is how I want it to move srry for the quality I recorded on my phone
quaint oasis
yup, if you follow the setup above you should be able to get this effect
signal hedge
Yep. You will want to have your nodes probably setup like this:
Player -> GunHo...
this one?
quaint oasis
yup :)
signal hedge
what does he mean gunholder?
quaint oasis
just a blank Node2D named gunholder
signal hedge
ok
quaint oasis
it can be named anything, renaming it just helps with organizing
signal hedge
yeah
quaint oasis
if you make a node a child of another node, it will inherit its parent's position and rotation
so if you rotate the GunHolder, the gun will rotate with it
signal hedge
how can i move it like in the vid tho?
quaint oasis
just put a script on GunHolder that rotates itself toward the mouse, like you had it before
signal hedge
yeah i have that
quaint oasis
you can probably discard the script on the gun
quaint oasis
yeah i have that
whats it doing now
signal hedge
but it rotates it doesnt move
quaint oasis
is the gun at the same position as the GunHolder?
if so, move it to the right some amount
signal hedge
it just flies off
quaint oasis
are you using the same script as before?
signal hedge
this right?
quaint oasis
is the script on Gun or GunHolder
signal hedge
the latter
signal hedge
no
quaint oasis
they should
signal hedge
ik the problem i think
quaint oasis
you need to move the gun out, not the GunHolder
signal hedge
this just looks at the mouse
quaint oasis
yup, thats what you want i think
signal hedge
wait lemme see
quaint oasis
the setup were suggested is letting GunHolder be the "pivot" that will rotate your gun
so youll need the GunHolder and the player to have the same position, and for the gun sprite to be offset by some amount
signal hedge
OH YEAH IT WORKS
FINNALLY
you dont know how long ive tried to make this thank you
quaint oasis
glad i could help :)
quaint oasis
it should if GunHolder is a child of the player
quaint oasis
huh..
does GunHolder have "top level" checked in the visibility section or something?
signal hedge
no but i checked it and it dissapeared
quaint oasis
well you dont want that checked, i was just making sure
signal hedge
oh ok
quaint oasis
youre not setting the GunHolder's global position anywhere?
signal hedge
no
quaint oasis
weird..
without knowing more about your setup im not sure why it wouldnt be following
signal hedge
they are fine being diffrent scenes right?
quaint oasis
should be fine?
signal hedge
ok anuwau i gtg
anyway
cya
wait
can i friend you so if i have another question i can dm u?
quaint oasis
id prefer not to add people i dont know, but you'd always be free to ask in this server again
