Physics LineCast

Hi,

 Following a user request, Please find a new action to perform a Physics LineCast

http://docs.unity3d.com/Documentation/ScriptReference/Physics.Linecast.html

Bye,

Seems awesome.
Cheers

Sorry I mean. This action is always giving me true. That´s wrong.
It is any bug?
I´m currently trying it one more time.
Cheers

Hi,

 Double checked, it's all ok. LineCast will return true if there is a collider between the from and to position ( or gameObject).

Damm  I´m so stupid.
I´m sorry Jean.
I was testing this action between two cubes. I thought collider of end gameobject would not interfere on this calculation. But it interferes.
Thanks for your action.
Cheers

Wow, this is really sweet!

Had I known about this I would have incorporated it into my targeting systems for my game much sooner rather than spending a weekend trying to hash together a system with raycasts and the like.

This is much simpler! Thank you Jean!

... This makes me wonder what else the Unity engine can do that isn't often discussed... I'm going to have to spend some time on the manual to see what it can do (I know I should read it anyway but since I'm not a programmer a lot of what it talks about goes right over my head.)

Hi,

 It's always important to read the doc even if you don't understamd it, Sounds weird but it's very true.

When I buy a big book an a topic, I always gance through it fully, and never stop on a feature I don't understand, but the vocabulary stays, and then when I face a problem, then I remember that it was somehow discussed, then it's time to open that book again and read carefully until you understand that bit. It works, cause then you only need to digest the general set of features, not all the details, and you come back to it when needed, only when needed.

I open the Unity doc maybe 20 times a day minimum! You can't remember everything, but you must know where to find it! Skip the scripts if you don't understand them, but read the rests, it's critical!

bye,

 Jean

Thank you, Jean
Just yesterday I needed such a thing and I'm just limited to the length the ray
Today I'll try to do it with the PhysicsLineCast

Hi Jean,

this works for me as long as a collider is between the two objects. How can I make this checking every frame in order to recognize if something has passed the line?

Would appreciate any help.

Thanks a lot,
Andi

I needed this for a project I'm working on- I mixed the Raycast 2 action with this Physics Line Cast action and added an option to filter colliders set to trigger

@ernilabs It uses repeat interval from the raycast action so you can set it to every frame with that.

Its on Ecosystem as well

Perfect! Thanks a lot!

Is there a similar thing working for a 2D project as well?
