This is a brand-new KSP reliability mod designed to cause some explosions make you pay for engine maintenance. The idea is that you have to perform maintenance for money and time and replace engines if their accumulated degradation is too much. Forum thread is here https://forum.kerbalspaceprogram.com/index.php?/topic/193467-181-190-paytoplay-maintenance-costs-money/&tab=comments#comment-3777542
Two engine reliability settings are available in editor. One for rated burn time and another for ignitions. They can be chosen within configurable limits. Adding burn time/ignition increases mass and cost of the egine. As you ignite and burn your enignes, they get colser to a failure (just running out of ignitions or a fail-while-running). Restoring engine's runtime takes money (and time if KCT is present). In case of KCT to-storage recovery you recover craft with the same engines condition. Press "maintenance" button to restore them if you don't want them to have higer fail chances next flight. This system is deeply configurable, see present patches. Copypaste the module definition for other engines and tweak the numbers as you wish.
Grab the latest release and make sure you have module manager (in order to patch the EngineDecay MODULEs into engines). The mod is built for KSP 1.8.1, tested with MM 4.1.3. Should work with ANY MM 3.x or 4.x though.
- ModuleManager. Only MM 4.1.3 is tested but it is unlikely that 3.x and 4.x will cause problems.
- KCT: PayToPaly is designed to be used with KCT, it makes restoring recovered craft take time.
- Kerbalism: K 3.8+ has a compatibillity patch removing own reliability from engines. For use with K 3.7- rename the .txt in PayToPlay/Support/Kerbalism into a .cfg. Kerbalism has a lot of interesting features and it is unacceptable to be incompatible with it.
KRASHWrapper.cs is under a different license, taken from KRASH repo.
I'd like to thank kerbalism contributors team, their open source and advice have been essential to let me code the plugin.
