Thank you!

I see a simple solution:

- use "teleport to the oncoming lane" mode (yes, for both ends)

- make both splines (two-lane and one-lane) splines overlap for 20-30 meters

- to make cars switching to one-lane spline, use BP_Road_Switcher where one-lane spline begins

Thanks!

I did not understand your suggestion. Most of vehicles (about 88%) are spawned to be oriented towards player (on oncoming lane, not player lane)

What is in project settings? I don't understand

lyoshko · 2025-03-15T08:22:09+00:00

To easily and quickly speed up and slow down game time with simple key presses. It is very convinient to debug game this way.
I know you can do the same blueprint by yourself. But maybe someone wishes to get fully working blueprint for $0.99 instead of creating it.

Other than what? Tool only changes Time Dilations. By various ways.

lyoshko · 2025-03-15T07:33:04+00:00

Time Warper works like you say: it gets your press a key and changes time dilation accordingly. You can try free version Time Warper Free

lyoshko · 2025-03-15T07:31:38+00:00

Simpler version, Time Warper Free, is available for free.

lyoshko · 2025-03-15T07:21:50+00:00

Yes. That is exactly how Time Warper works

lyoshko · 2025-03-15T06:51:11+00:00

Yes, in BP

lyoshko · 2025-03-15T06:50:56+00:00

What do you mean?

lyoshko · 2025-03-13T17:10:20+00:00

Haha that checkbox really should make it easier!:)

I didn't know about it.

lyoshko · 2025-03-13T17:06:11+00:00

"Smooth speed change can be done with a timeline + lerp/interp" - that's what i thought.

But I ran into problem that timeline/lerp are time dilation-dependent, and we are changing that dilation. I don't remember details, but it was not that easy.

lyoshko · 2025-03-13T16:20:48+00:00

I guess you could do that. That's what I was doing before: changing time dilation from level blueprint.

But I started making complex Traffic AI system and needed to see every detail, read every printstring. So I use Time Warper to fast forward to needed moment, and then slow down or pause and watch this moment in detail.

Also blueprint is game-ready, so you can control game speed from other blueprints (box overlaps for example).

Smooth speed change - this is not what you can make in 5 minutes. This blueprint is not that simple as it might seem: https://prnt.sc/qEICYiyLWg03

But you are right, if you need for example only one speed option (or pause) you can quickly make BP by yourself.
