Hi @Machtnix, I'm not sure if you needed the same thing as me but here is a picture/image that describes the idea for swapping 2 waysystems in order to achieve complex character resizing.
Idea:
1. Create a way system (name: waysystem A)
2. don't forget to add all your way borders and way points
3. important: create another way-point-strip outside the way border. Set the Character Size there.
4. Copy/Paste waysystem A. name of copy: waysystem B
5. Change the Character Size in waysystem B's strip of way-points (outside the way border) important: don't change anything else - Inside the way borders the two way systems should be the same/identical.
6. Create two action areas and write conditions to check "which way system should I display now?". Between the two action areas you should define/use the same Character Size on both waysystems in order for the scaling to be smooth!
I am not sure if this method will cause problems down the road, but so far I'm really satisfied and it's relatively easy to make, even for more complex scalings.
As seen on step 6, the only trick/consideration is that the waysystem swapping/transition should happen in a region where all waysystems have the same character size. (obviously)
Therefor it's easier to make this part horizontal and not vertical
Of course scaling with LUA would be much safer, but I was looking for the laziest thing possible :-)
