Would it be within scope of this PR to also allow building small zero g rolls without cheats if the vehicles have these fallback sprites? The small zero g rolls look great with all of the vehicles i've tested thus far. The large zero g rolls are a bit off especially with longer vehicles so they should probably stay cheat only, but they do look so much better now. |
|
Yeah could do. It's already possible to build diagonal bank transitions without all the sprites. I could put it in this PR or make another afterwards if you guys want to do that. Let me know if you think there's anything else that can be done with the large rolls. I did try several different things before landing on this. They can always be changed again if somebody comes up with something better anyway. |
|
For the most part i feel like the large roll fallbacks are fine and are probably about as good as they can be all things considered, they actually look pretty good with the shorter bm trains. Perhaps some corkscrew sprites could smoothen it out a bit but i feel like that might make these a bit too complicated and also disallow some vehicles from using them as there are some vehicles with twists but no corkscrews (bm flying trains comes to mind) |
|
Is it intentional that vehicle sprites are at a slight angle when entering/exiting small zero g rolls? |
|
The rotation issue is in the track supposition data, see my other pr #24366 those aren't fallback sprites, they are just gentle slopes, it's always been like that. There's not really an issue with using corkscrew sprites implementation wise but they are way too angled for this. Good point about the flyer train though. |
|
In that case i'd say this mostly has my approval now. I'd just like to see if changing the small zero g roll building requirements would be in scope as they do look excellent with every vehicle i've tested. |

I've made it so that you can build the small zero g rolls if the trains have sprites for gentle banks, inline twists and inverted. I think this only affects the twister rollercoaster right now, it's the only one that has the vehicle sprites and zero g rolls in the normal track piece selection. |
|
Hm, it'd probably make sense to add them to the LIM launched's normal pieces later on then as those vehicles are also able to make use of small zero g rolls and have them irl. But that's definitely something for after this PR. |

Having these available on the twister coaster without cheats just feels right, works as expected elsewhere too from what i tested. |

There was a problem hiding this comment.
If @ZeeMaji is happy, then I’m satisfied this is good to go.
Any reason why you think this needs a network version bump, though?
|
I thought that changing when a track piece is allowed to be built without cheats would need it, but I actually don't know. |
Pieces that get hidden because the vehicle lacks sprites are just a UI thing. Could you take out the bump and rebase? |

Gotcha. I've rebased it. |

This improves the fallback vehicle sprites for Zero G Rolls. Apart from one pitch/bank angle, they have been changed to fallback to the inline roll sprites. I tried to see if any of the corkscrew sprites could be used, but I didn't think any were suitable, and in my opinion having a smoother animation overall looks better than it changing angles several times. I also renamed a vehicle paint function that seems to have an incorrect name.
