New target script change

Beginner Questions
#1

I just updated to the 4.1.10 patch (so far I’m liking it!), (I also haven’t used A* in a long time so I’m catching up) and I have a small issue that I was hoping could be easily fixed.

Since the new AIDestinationSetter script allows for the targeting to be slightly different than before, I am trying to set the target destination with a raycast. I am sure there is a script out there that works, but for the life of me I can’t figure out how to send the hit.point of a raycast to the AIDestinationSetter script. Is there a way to do this or should I just add the raycast script into the AIDestinationSetter script?

Mostlt what I am hoping to do is use A* for a multiplayer game. It seems like it would be easier to have each individual player grab the coordinates of a verctor3. I am wondering if I have to make an empty object to be a target if each player will be able to have their own target (I know its possible, it just feels like more work)

Hi

If you are trying to set it using a Vector3 you can skip the AIDestinationSetter component altogether.
Just use

var ai = GetComponent<IAstarAI>(); // AIPath/AILerp/RichAI script
ai.destination = hit.point;

And make sure that you have removed the AIDestinationSetter component.

Works perfectly! Thabks so much!

One final small adjustment, how do I make my player move to the center of each node, or the center of the nearest node, rather than moving to the exact point where I click? I remember setting it up with the older version but I can’t find how I did it. Any help at all would be great!

Hi

Simply set Seeker -> Start End Modifier -> End Point to ‘Snap To Node’.

#5

I actually tried that, but it doesn’t seem to make a difference. I can still click on any location and my player will move to the point clicked, not to the center of the nearest node. Is there another spot I should be checking?

#6

Huh. No that should be everything you need to do. How does the calculated path look (enable Seeker -> Draw Gizmos)?

#7

That’s what I thought, but it isn’t working. I know in the older version it worked just fine.

I have Draw Gizmos set to on, and have tried all possible combinations for start and end point snapping. A line is still drawn, but it foes not move through

Actually I may have figured out my issue. It appears my models are all much larger than the scale for the grid of the A*. I’m going to try scaling things down or the grid up and see if that works

#8

Yup, that was it. I just needed to increase the node size to 2 and adjust the world position and it all worked just fine! Thanks for the help!
