Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Why Aren't My Lanes Switching Properly?

I am following this tutorial here.

https://www.youtube.com/watch?v=KdkDqk_YBS4∈dex=5&list=PLL0cLF8gjBpoTwM62rvhgmsk_Xp1_G1Vn

Below are pictures of my work.

alt text This is my tile that repeats itself to make the track endless. My problem is that whenever I switch lanes in game, it places me at the location of where the first was instead of the current track.

alt text

These are the locations of each spot on the tile where I want the character to move to. Before I noticed the problem where it would take me to the first tile, it would also move me to the left said of the track, meaning off to the left of Lane 0.

alt text

These are the variable representing the lanes in the ThirdPersonCharacter Blueprint. The Array Locations are the same as the Lane Locations I marked above.

alt text

This is the code I followed from the tutorial that switches the lanes.

Can anyone see what I did wrong? Or even an a better way to do it? All help is appreciated!

I suspectthe Timeline doesnt Finish before you Start it again upon hitting the next Tile, and therefore the Lane Index never gets updated

@mightyenigma The timeline only last .10. I could try changing it but I feel like it is long enough for it

@mightyenigma I watched my event graph fire off to ensure it was doing it in time in order to fire off the SetActorLocation node.Everything worked fine it that. So I'm wondering if it's some sort of error in where it sets the actor.

alt text This is his timeline in the tutorial. It's small but when I zoom, I can see it well.

So can you confirm that Lane Index is getting set by the Finish execution pin from the Timeline? My suspicion is that Lane Index does not get set, so it is always zero.

Uploading a clip of it firing and finishing on Youtube right now so I can post the link.

https://youtu.be/brH3KzoTdhI I'm hoping I am showing you what you meant you wanted to see.

Yep, that proves well that it is NOT the problem I thought it was. It all looks like it should work. Maybe try ticking the Use Last Keyframe checkbox on the timeline.

That doesn't change anything. I may just have to start playing with everything on it.

Sorry I couldn't figure it out!
