1. You could need multiple parts. Are you going to bother the user experience with 10 pop-ups when he is only trying to apply a simple tune sheet?
2. What if you accept the first 5 parts, and reject the 6th? Are you going to undo everything or just abort and leave as is?
3. What if the player doesn't even have money for the 10 parts? Are you still going to show the pop-up until it runs out of money, or abort from the beginning?
4. What if the tunning requires permanent changes like bodywide and engine swaps?
5. What if the tunning uses parts that are not available anymore due to updates?
6. What if you are trying to apply a tunning that has parts to be brought, but the lobby doesn't allow that part? Is it going to abort it completely or apply it partially?
7. There is no option to buy parts in the menus you apply tunning, or in the session overall (like when you are inside a lobby). You can buy tires and ballast, but not other parts. Probably there is a technical reason behind that, which could break the game or demand lots of changes in the code.
8. You guys surely remember they had to disable (pre saved) sheets from Daily races with tunnings cause of the exploits. Imagine the number of new exploits using this "buy parts" and "undo parts if aborted"
Its possible to do this on paper (the idea)? Surely.
Its possible to do this in the current game code? Maybe.
It will probably be a lot of work? Surely.
It will probably introduce a ton of exploits? Surely.
1. Single window with a scrollable checklist.
2. Checklist means only what you choose is equipped.
3. Buy what you can or reject the ability to buy it until you have enough for the full sheet.
4. The cost for engine swaps and new bodies goes on the tab, or the new body is ignored and the weight reduction/rigidity specified is equipped. This does make the new body option redundant and also means you’d have to buy a new car to avoid this in all situations.
5. This is probably never going to happen. And if it’s an aero part, labelling the part “part A” so that it simply equips part A no matter what, even if the original part no longer exists, would work. As a fallback, if part A doesn’t exist at all, then reject the tuning sheet or use a different aero part. For tuning parts, you could either make the tuning sheet not available to use or show an error explaining that the part is no longer available and will not be installed.
6. The following would work I think - “This lobby does not allow the specified parts from this tuning sheet: Parts listed here”
7. Sure, but they could add it if they wanted. I don’t deny it might be complicated and not worth it for GT7 at this point in time, but I don’t think you need a tuning shop screen to buy parts, they have the part IDs in the code and code that equips it to car, they can use that from the Showcase menu I’d imagine.
8. Seems pretty simple to me. Do you have the money? You buy parts then and there and they’re equipped as if you were at the tuning shop. If you can only afford some, but not all parts, then you buy those and equip them, the other parts are discarded from the “tuning shop session”, so to speak.
Not really seeing the potential for exploits. A tuning sheet will still have the same parameters that the game reads to determine if a car is tuned or not, and thus if the event doesn’t allow tuning, the car won’t be entered.
An alternative way to do this (but probably old school) is to store the attributes of every car in its unmodified state, along with exceptions for if the car has oil, engine, or chassis wear, and use that as a way to check if the car is modified, though it would need updating on every update that changes the PP calculations.
