Unity Basics - Waypoint Path system in Unity Part 1

[@MetalStormGames]

If you would like to see more videos adding on additional features to this waypoint system please comment below and let me know what features you recommend covering. Thanks for watching!

[@dippedincocoa1640]

Thanks for the tutorial. It helped me to understand waypoints. However, how can I add an A* algorithm with this system?

[@MetalStormGames]

@@dippedincocoa1640 A* is a fairly complex path finding algorithm you would need to find a series that walks through it step by step. Sebastian Lague has a good one on his channel but it is quicte complex. if you are new to path finding I would suggest learning one of the more simple algorithms first like Breadth First Search and then work your way up to implementing A*.

[@낮잠-c3h]

Hello, thank you for helpful tutorial. My question is, I wonder if there is a way to draw curved line between Waypoints. I wanna make gameobject move smoothly when it turns other way, but the waypoint system I made only can draw direct line... I think It may relates to interpolation...

[@MetalStormGames]

@@낮잠-c3h You can make Bezier curves to do that but it gets a lot more complex. I cant remember who has good curves tutorials but I believe it was CodeMonkey's channel that had some great ones.

@@MetalStormGames Yeah I was actually looking for something like this to use on a few sharks I wanted to move around below the water, I used the implementation you showed in the video. The only thing I can't seem to figure out yet is how to smooth the rotation properly, perhaps you can point me in the right direction. In the video as you mentioned using LookAt changes the rotation instantly, and what I need is for my object (the shark) to go from waypoint A to B and when it's close to B start looking at C. I think I figured how to calculate the approach but not the interpolation properly. In the distance approach I made another function which basically calls GetNextWaypoint to check (but not change) which one would be the following waypoint, so that I can calculate 'where' it needs to look at, so in this case the shark is going from A to B, and starts looking at C when close to a rotationThreshold near B. The thing that's driving me crazy is the Quaternion.Lerp or Quaternion.Slerp interpolations, because they don't seem to be working the way I expected them to work. I first calculate a rotation using LookRotation() which I then tried to give to the lerp but it rotates weirdly, it rotates too little before reaching the next waypoint, or not enough to complete it's full rotation by the time it reaches it. I also tried Quaternion.RotateTowards without success. If you have any tips on how to approach a simple lerp or smooth effect for the rotation going from A to B, while looking at C waypoint, I would appreciate the help.

[@MetalStormGames]

I am never the greatest with rotations but you will want to look up Slerp in the unity scripting reference. It will let you smoothly move between 2 vector directions. There is an example on the documentation at the link below. I hope to make some videos on smoothly rotating in the future but it might be a bit before I get to those. docs.unity3d.com/ScriptReference/Vector3.Slerp.html

[@kevkas]

@@MetalStormGames Thanks for replying. I ended up having to go with a totally different approach: bezier curves, I didn't realize it before but that's kind of what I was needing, it's a bit more complex but I found another nice tutorial which was a good place to start. Thanks again for taking the time to reply to me. :)

[@camiloguerrero2]

Great video. I used it for a railroad intersection arm gate, but when the arm gate is down while is down I need it to stop, and when is up, I need it to continue going. So could you please tell me how to add this?

[@MetalStormGames]

Check out the recent Part 2 of the video I made, it doesnt do exactly what you want but you can change it to very easily. I show how to set it so you can make the player move forward or backwards on the waypoints. You can easily do the exact same thing with the player and add a bool variable for isMoving and then if the intersection arm gate is down set isMoving to false on the player, when it goes back up change it to be true and that should work just fine for what you need.

Really great video! I'm super new to programming in Unity (and programming in general) and I would love to make the coroutine you described at 27:52 to stop moving, rotate, and then start moving again after the rotation is done but I don't know how. Any chance you have time to help me with that code?

Would probably be a lot easier to join my discord server in the description and myself or someone else on there can try helping out with that but in general that should not be too difficult.

[@ogrenkurtul5429]

Hi Dear. First of all, sorry for my english. My problem; I am a beginner coder. My Project is a 2D There is something I want to do in my project. My character will patrol the way point. While going to each point, it will turn its direction to that direction. At each point, it will wait for the time I set. There are at least 30 points on the way. When it reaches the last point, it will wait here for 5 seconds and continue from the second point.

[@MetalStormGames]

You will want to look up Coroutines for that. I dont currently have any tutorials on using them but hopefully will in the future but if you youtube Coroutines for unity you will find great resources.

@@MetalStormGames Thank you :D

[@DoubleRaw]

Very helpful but I would have used type GameObject instead of Transform. Would that be a bad approach?

[@MetalStormGames]

Not at all, whatever works best at the time for you. If the main thing you will be accessing is just the position then storing it as a transform just saves you having to type obejctName.transform each time but they will both work the same.

[@DenisClan]

I have a problem that between each waypoint my characters stops moving for a long time and after like 30 seconds to a minute starts moving to the next waypoint. can you help me?

[@MetalStormGames]

The first step I would take is to use some debug messages to see where the code is sitting at during those pauses, I would guess it is probably something with the check if the player is close enough to the next waypoint and its very very slowly trying to move closer to the target but thats just a guess. Put in some debug messages inside each section of code one by one to see where the problem section is and that should help you narrow it down a lot.

[@moviescorner11233]

28:37 how to move camera like this? any recommend video to use mouse or keys for this, please?

[@MetalStormGames]

Not sure what you mean, at that part I was just navigating in the scene view and nothing with the camera itself. If you mean how to move around in the Scene view you can use Flythrough mode which all you have to do is hold the right mouse button down and then use the WASD keys to move around inside of the scene view just like you would control a character in a first person shooter game.

[@moviescorner11233]

@@MetalStormGames got it, thanks

[@t-flow99]

This helped me a ton! but do you know how to make it turn smoothly?

[@MetalStormGames]

For turning I would look in to using Slerp or SmoothDamp to adjust the rotation, you could smooth it out over a few frames.

[@MetalStormGames]

I am not sure when I will get a chance but you mentioning that made me want to make a 2nd part video where I can show how to make the agent rotate smooth towards each target and maybe a few other features. I am going to try working on it this week.

[@simonsobo4644]

Actually, the error message is below: Assets/WpMover.cs(30,38): error CS7036: There is no argument given that corresponds to the required formal parameter 'maxDistanceDelta' of 'Vector3.MoveTowards(Vector3, Vector3, float)'

[@adslpiulentoditalia2545]

Is there any chance to add more points for example I want to set to the left right and forward point and then close to the end position. Is there a way to do that?

[@MetalStormGames]

Not sure exactly what you mean but if you want to add more points on the path just duplicate the gameobject waypoint, the system works based on how many children there are in the waypoint system so you can add as many as you want by just duplicating the path waypoints. Is that what you meant?

[@basemshaban9609]

شكرا جزيلا يا صاحبي

[@_SF_Media]

Thanks for the detailed tutorial. Have one for door/chest/item interactions?

[@MetalStormGames]

That wouldnt really be a waypoint system but a seperate mechanic. If you are looking for doing that using Unity's NavMesh system I do have a video on making doors work with NavMesh Agents (its actually a few videos). For manually moving like this it would really depend on what you wanted it to do and how you structure your game so not really a quick easy answer on that. If you are using a waypoint movement system like this though what comes to mind for me would be to have a waypoint that goes through a door but have a trigger collider on that door and on the object moving between waypoints look for colliding with a door. If it does collide with a door then wait until its open and then pass through. (you may want to check out my navmesh door series either way for that). If that wasnt your question then explain it a bit more and I can try to answer.

[@_SF_Media]

@@MetalStormGames Was actually thinking a different system all together, perhaps a standalone kind of thing that can be added easily to any project. I'll also check out the waypoint with doors video too.

[@MetalStormGames]

I can add that to my list, but yeah check out that video series and it should give you a general idea of one way it can be done. I am sure there are tons of ways but thats how I usually do it.

[@camiloguerrero2]

great tutorial!. Could you please help me with something? Im having an error in the waypoint mover script line 30 transform.position = Vector3.MoveTowards(transform.position, currentWaypoint.position, moveSpeed * Time.deltaTime); the error says null reference object. Object reference not set to an instance of an object. Do you know maybe something about it?

[@MetalStormGames]

Null reference means that something is basically empty in that line, check to make sure there is something in currentWaypoint. More than likely it does not have a refrence in the inspector or there are no children objects under the waypoint gameonject in the hierarchy. If you have trouble figuring that out it is probably a lot easier to explain how to troubleshoot on Discord if you want to join mine the link is in the description and I can definitely help you figure it out.

When I switch back to Unity from my IDE (Visual Studio) unity hangs for a few seconds and then runs correctly and fast. Suggestions on making it as fast as in the video?

[@MetalStormGames]

Thats normal it has to compile before you run, I just edit out a lot of that time so is not wasted in the videos. It has been taking a lot more compile time in the recent versions than before though I am not sure why that is though. I hear the newer version coming out has improved on the compile time a bit but not sure how much.

[@Fraaiiz]

Nice video :) I was wondering if it was possible to know the percentage of the path made by the agent and that it increases constantly and not only when the node is reached ? (to make a race positioning system based on the progression)

[@MetalStormGames]

I am not sure how off hand as I have never tried that but I dont see why not. If I am understanding you right I think you could just save the previous point and then calculate the distance between that one and the next waypoint to get the full distance between them. Then you could just work out the percentage based on where the player/objects current position is in between them if that makes sense?

[@Fraaiiz]

@@MetalStormGames I'm sorry to tell you that I've struggled about it for a full day as I learn by myself but your idea... was AWESOME !!! It works fine, I've just to put all my floats in an array and sort it out :)

[@gerritson7178]

How to I stop it from looping, I want to make a tower defense.

[@MetalStormGames]

That would be a really good one to practice and try on your own to learn how these mechanics work but if you get stuck in the Else condition inside of the GetNextWaypoint method just return the last waypoint instead of the first one and I believe that should work for you.

[@lukassudek]

I'm a beginner and I need help editing a script. I have 50 waypoints, the player has a variable called "position" at the default value of "0" (starting position), how to do that if position = 10, so the player only reaches waypoint number 10 and stopped?

[@MetalStormGames]

I would restructure the setup from this video a bit for that. In the method for GetNextWaypoint I would pass in the position variable that you have and then do a check if the current waypoint has the same index as your "position" variable. That is a big change from what is shown here so it is hard to explain in a quick little response but if you want to join my discord myself and anyone else online can give you some pointers as you need them.

[@lukassudek]

I'll join your Discord thank you very much

[@gamergarand9894]

Bro can you say how to add animation when the player is going through waypoint

[@MetalStormGames]

For something like a walk animation? You could just use bool or triggers on the Animator and in the script that moves your object set them there. Basically in the mover code when the object is moving set a bool like isWalking to be true which changes the Animator state to walking and if its not moving set isWalking to false. Make a transition in the Animator that uses isWalking being false to play an Idle animation. That should get you going in the right direction but if not feel free to join my Discord server with the link in the description and we could help you out a bit more on that.

Thats a hard question to answer without knowing what you are actually doing or want to do but a quick way you could make an if statement to check if there is any player input and if there is put the movetowards line inside that if statement.
