I have a bug with my wrong way indicator when there is a junction on the track.
When I look forward, all is good, but when I look forward to the junction, wrong way appears.
I use the regular approach using dot product:
forward = dot(next section - current section, ship direction) > 0
So I thought that I could do the same with a junction and take the max:
max(dot, dot as above but with junction)
But it’s not convincing, angle at which wrong way shows up is weird, depending of ship position relative to section.
Here’s a picture so you can understand:
- the triangle is the ship
- a section is made of quads , here I’ve painted the floor of 3 of them
- the lines pass through section center points
- white denotes a regular section
- magenta means section has a junction
- blue/orange are junctions (start/inside)
I have the feeling that I could do something with angles between the different sections.
Something like the dot threshold be adjusted according these and ship position.
However, I don’t really know what to do exactly…
Any clues are welcome!
