Actor trailing other actor

Atlanten

Hello

I want to make an actor copy the position of another actor, but time delay it so that it trails after rather than sit on top. So if I had several actors doing that, with increasing time delay, I'd get a caterpillar-like motion.

I can't find a way to delay the actor's timing.

Do you know how to achieve that?

Any help would be much appreciated. Thanks!

Not totally sure if this'll work, but maybe with some tweaking.

You'll need to create two real attributes to track the location of the actor you're following.

Every second, constrain the location of the main actor to the two attributes made earlier.
Have the following actor move/accelerate towards those coordinates.

Thanks for the advice!

I tried it out, it kind of works, but it's not looking very smooth.

I'm trying now to constrain the positions, but subtracting the lead object's velocity from the follow object's position.. Looks like I'll be able to get a spring-y lag.

I was hoping for something like a time controlling function? So you could just set the object's relative time to -1 second. Would be awesome

here is a test without the usage of any timer-behaviour...

SDMG,

That is smooth... nice! I would love to see the code.
I will need something like this for a health bar for one of my BOSSes.

Would be a great one for the WIKI, BTW.

I don't think I'd ever want to add you to my contacts list with an email address like that, Atlanten

Atlanten

Ha ha! It's not as bad as it seems. My first name is Måns, and I use it for chat

quantumsheep

Sure, lady, tell it to the judge!

And SDMG, can you send me your file? It'd be very useful for some of my games! I think you already have my email!

Oh, and you get a mention in the credits of every game of course

Update!

For anybody looking for a solution to this, example 2 in this article got it working like a charm:
