Shooting a raycast through an object?

[DIamod]

Hi, I am having trouble understanding how to make sure that a raycast always shoots in relation to the object it's firing from.

I have a unique camera setup that the camera never moves, only a reticle overlay does.

My scene looks like this the green line represents the expected raycast direction and the orange the actual raycast direction

I came up with the solution of making the raycast source (reticle) always point towards a 2nd object before passing through it.

A top-down view would look like this


I cannot find anything in the ecosystem for this, so any help would be appreciated.

Hi.
The image link does not work.

could you also show how you set you fsm/state/actions?

Maybe you can turn the raycasting game object, rather than the raycast itself, towards a target?

Thanks for the reply, both images are showing for me I can try a different image host, however.

Here is my FSM https://ibb.co/m9RP9fv

the problem is that as the object rotates in the scene it's always firing in the same direction. The following is a gif showing the debug ray, as you can see its always fireing north, rather than the direction that the crosshair is facing.

Hi.
I think imgur is having issues at the moment.

On the raycast action. do you have 'Space' set to self?

I figured it out thanks!
Changed space to Self
from game object to itself
and a direction of Y -1

Not sure why but this combination seems to be working

hi, space Self will use the object rotation.
space world will use the set direction Vector no mater what rotation the object has.


so if you would set a direction y 1, in world space it will always send upward no matter if the object is rotated to a certain degrees.

if object is rotated 180 degrees in z, then the raycast would be downwards.
