QUESTION
I bought astarpathfinding project pro recently. I am making enemy ai and I want it to move randomly before it finds its target. My project is in 2d. How do I pick a random position on the grid? if you can, can you show me some example of it?
...ANSWER
Answered 2021-Jan-26 at 01:50Not really sure about the plugin that you bought, but If you are using tilemaps, you could iterate over every tile in each tilemap in your grid(only once on level loading) and generate a random number of x and y to choose a valid tile position from and make the Ai move there using the A* algorithm.
Edit: May not be the best way to write this, but this is how I iterated over them in the past, you can add or change things in it for your future needs if you want.
QUESTION
I have a class that I'm trying to use, but in main
function ёstartё doesn't execute with following error expression preceeding of apparent call must have pointer-to func type
ANSWER
Answered 2020-Jun-29 at 08:47You have "start" as member and "start" as function. Rename one of them will fix your error.
QUESTION
I don't know how to desribe this problem, but my issue is, that my function "Pathfinder" somehow changes the data of my int[,] matrix. Is there a way of preventing this without changing my Pathfinder function?
a bit of my code:
...ANSWER
Answered 2020-Feb-11 at 20:15Judging from the output that you are getting AStarPathfinding.Pathfinder
is indeed changing the matrix. This is just a thing that methods can do to reference types, or value types passed with the ref
modifier. This is because those parameters are passed by reference, so the callee and caller are actually dealing with the same object. Some methods do this, others don't, and AStarPathfinding.Pathfinder
just so happens to be one of the former.
It sounds like you can't change the implementation, so the best thing you can do is to pass a copy of the matrix. One way to do this is:
QUESTION
Ive create a class with two abstract method.
In one method I return my generic type U in a list as required by the return type in my abstract method List
In my second method I just return U as required by the return type in my abstract method but I get a type error
error CS0029: Cannot implicitly convert type LB.HexSphereBuild.HexTile' to
HexTile'
I dont understand why this is an implicit conversion? Especially since all the types are under LB.HexSphereBuild namespace apart from my public abstract class AStarFindPath which is using LB.HexSphereBuild;
Please help
...ANSWER
Answered 2018-Apr-12 at 14:33You already defined T
and U
, defining them in your methods again means the T
in all methods might be a different type. That's not what you want, remove the generics on the methods:
