  v5.4.4 DOTween updated to 1.2.235 changed: local checkbox to dropdown, none/toPath/toObject. toPath is the same as enabling local in earlier versions. toObject can be used to let objects move on path formations from their local position minimum required Unity version: 2017.3.0

  splineMove.tween != null would be sufficient in most cases. If you pause the tween during gameplay, add && splineMove.tween.IsPlaying() as an additional statement. & 3. The "currentPoint" variable is the current active waypoint index. First waypoint: currentPoint == 0, last waypoint: currentPoint == waypoints.Length - 1. In case of "ping pong" movement, the "reverse" boolean indicates the current direction. However, this is reset immediately after reaching the final waypoint. https://www.rebound-games.com/docs/sws/splineMove.html If you wish to not only check for these states at a given time, but also receive events at the time they happen, please look into waypoint events.

  It depends on what you're using as an "up" axis in your modelling application, but that's basically what I meant with the point above: go back in your modelling application and rotate the model there E.g. in Blender there's a different "up" orientation one has to apply the rotation to before exporting.

  Thanks for the feedback, I'll sneak a "jump to point + reverse" sample into the next update. I'm not really 18, that must be the default value ;) In a few years double of that...

  Finding the direction of the path before walking it?

  Sure! @FeastSC2 said in Finding the direction of the path before walking it?: 1) How to know in which direction the path goes before walking on it. Is this something that's possible? Simple Waypoint System does not provide this information, but DOTween does. You can get a Vector3 from a certain percentage along the path like this: //tween is a public variable of the splineMove script //0.01f = 1% further on the path Vector3 posNext = tween.PathGetPoint(tween.ElapsedPercentage() + 0.01f); //use current position and posNext to get direction or rotate to posNext ... @FeastSC2 said in Finding the direction of the path before walking it?: 2) How to get the index of the next waypoint with navmove? The navMove script has a "currentPoint" variable as well, which always points to the next waypoint. E.g. after passing waypoint 1, currentPoint equals to 2. If your question is more directed at 1) but with navMove, I would suggest looking into NavMesh.CalculatePath and NavMeshPath.corners.

  BUG: the OnWaypointChange(int index)'s 2 bugs.

  Thank you for this post. On PingPong mode, OnWaypointChange(int index) is indeed called twice, as the moving direction changes on the first and last waypoint. While it seems to be the same waypoint, it is actually not - there is a difference in the reverse boolean variable. With reverse = false and index = last waypoint, the object is still facing forwards. With reverse = true and index = first waypoint, the object turned around and is now facing the other direction. OnWaypointChange is called on both events, for you to decide exactly when your event should happen. You would check the reverse variable value for this in your own script (and to avoid your event being called on the "other side"), without modifying SWS scripts. Regarding your second point: in the case of index = -1, there is a return statement in the method already and currentPoint is not set to that value.

  If you're working with multiple third party assets and modifying their source code, I would recommend using version control and checking for the modified parts on each update. While I understand where your request is coming from, it is not feasible for me to post the exact code lines and changes for each bugfix. Most of the time, fixes are not done in a one-liner and I do not keep track of all changed lines in the development track. In this case I can propose two types of fixes: Short version: In the splineMove script replace all calls to StopCoroutine(Wait...) with StopAllCoroutines(). Not future proof but does the job. Long version: Save calls to StartCoroutine(Wait...) in a separate coroutine variable and let the StopCoroutine calls use that reference. This is included in the next update. Edit: Live in 5.4.5

  Sorry for your time, that was my fault, 2 waypoints at the end were so close to each other(I need one for event) and I accidentally set Path Type to "Catmull Rom". Setting it back to Linear fixed the issue. I'm really sorry. But I needed that link with explanation about all ease types, so thank you so much!

  Glad you figured it out. The "currentPoint" variable is an internal variable and can, but should not be, modified at runtime with its sole purpose of telling you the current waypoint index on the path. Whenever you want to start a new movement iteration, the "startPoint" variable is checked and determines where the object should teleport/move to for beginning its path. That's the correct variable for your use case.

  @matt33315 said in SplineMove.tween.ElapsedPercentage() = 0 and not 1 when spline move gets to end of the path: I checked the IsComplete() method too but that is returning false. Once the tween has been killed/discarded all the properties on it appear to be useless. Yes, that's why I wrote you have to do a null check prior to that as well. Otherwise if you would like to keep the tween active all the time, you either have to set auto kill to false or modify the movement script at the tween initialization.

  DOTween Pro has a path component, correct. Our movement scripts allow for more settings though. You could use the Pause event on each waypoint - please see the Camera sample scene.

  Hi Philippe, did you see our PlayMaker actions contained in the Extensions folder? There is a separate manual for it too. For switching paths, you would use our SetPath method / action, also demonstrated in the PlayMaker sample scene. You can explicitly force the movement script to reset its position to the beginning by calling ResetToStart (public method) on it prior to that.

  No, there is no dictionary or list saving the relationship between movement scripts and paths. You would need to do this manually, e.g. FindObjectsOfType and then checking their path container.

  You can change the speed value in the component inspector, or at runtime by calling the ChangeSpeed(newValue) method. https://www.rebound-games.com/docs/sws/splineMove.html

  SetPath() is starting the movement directly, which is why you would want to modify the startPoint beforehand. Glad that you figured out how to do it with the progress value as well.

  No, I understand that. I mean after creating bezier path with children that have 2 additional children, if you create a waypoint through a bezier path manager component, it won't be treated as a waypoint and, well, events won't work. Thank you for help again, good luck :)

  Could you please specify what example you mean? Which scene and sample number? All objects are moving on a designated path when using the splineMove script, which is tween based. The other type of movement would be navMove, which is navmesh based. Please have a look at the PDF manual included in the package for instructions on how to create paths and use these scripts. For programming, open our scripting reference linked in the pdf as well. If you are looking for a specific sample, open the associated sample script and have a look at how it is coded - there are numerous comments to explain it.

  Thank you for help. I ended up creating an event at the end of a path to manually reduce the speed over time and that works perfectly now. Also I just changed my paths from Beizer to Spline and now it doesn't reset the rotation at the end of a path. Also, if someone face this trouble and you don't want to reduce speed by event, you can rotate an object by event, Lerp() or RotateTowards() will work in this case. Events are really handly here, didn't notice this at first. Thanks one more time, good luck!

  Hello, it is correct that moveToPath needs to be enabled before calling StartMove() or SetPath(). The reason behind this is that moveToPath not only is a checkbox in the inspector, but an actual internal toggle for the script whether or not the object should move to the path. It also stays enabled until the object reaches the path, so it can be checked in order to figure out whether the object is currently moving but not on the path.
