Gameplay AutoStage

[Maxi]

AutoStage automatically activates the next sequence whenever active engines run out of propellant.

Works during auto-burns (continues the burn instead of aborting) and manual burns. Cascades through multiple empty stages if needed.

Toggle via the AUTOSTAGE button on the BurnControl gauge panel.

Features

• AUTOSTAGE toggle on the BurnControl gauge panel.
• Cascades through empty / decoupler-only stages so the engine on the next live stage lights without manual intervention.
• Configurable engine ignition and decoupler delays per part variant (Settings > Mods > AutoStage Settings) with per-vehicle overrides via the Part Window.
• On-screen countdowns (Decouple in X.Xs, Ignition in X.Xs) during a delayed stage so you can see what is about to happen.

AutoStage v0.2.1 - Ignition Delays​

Previously, AutoStage would fire decouplers and ignite the next stage's engines immediately after the last stage was spent.

v0.2.1 adds configurable ignition delays. After staging, decouplers fire immediately but engines wait before igniting, simulating realistic engine spool-up time.

You can configure the delay per engine variant in Settings > Mods > AutoStage Settings, or override it per-sequence on a specific vehicle by right-clicking an engine and opening the Part Window.

The per-engine delay Config is stored in the mod's own folder, so removing the mod won't mess with your saves.

Graphic design is my passion.

I kid, easy fix I'm sure, but a cool feature to have until it gets baked in! Thanks!

haha yeah i will try to fix it soon-ish

I am not sure where to place it tbh.
It is close to the "Auto(burn)" button and i did squeeze it in the lower half because did not want to make the entire panel bigger just for that one button.

I will try to either make the button a bit wider, or the text a bit smaller so that it fits properly within the buttons bounderies

Pls let me know if you have any further reccomendations.

@Kiwi Shark fixed

The UI does not let you make the rectangle wider because it would collide with its neighbors, but i am able to shrink the text.
I dont like that the text is smaller than the text in the other buttons but it is better than the text colliding with its buttons boundaries

AutoStage v0.2.3 - AUTOSTAGE button sizing fix

Small visual update: the AUTOSTAGE label on the BurnControl gauge panel now fits inside the button properly.

No functional changes.

AutoStage v0.2.4 - Fix Auto button disabled after auto-staging

Fixes a bug where the Auto burn button stayed disabled with "Burn duration is empty" for any burn planned after AutoStage had cycled through stages during a previous burn.

Tested against KSA v2026.4.17.4184.

AutoStage v0.3.0 - Decoupler delays​

Adds independently configurable decoupler delays alongside the engine ignition delays, on-screen countdowns during a delayed stage, and fixes a wasted 2-second wait when auto-staging the launch stage.

Highlights:​

- Per-decoupler-template delays (default 0) with per-sequence vehicle overrides. Both the Mod Settings tab and the part window expose the new dimension.
- "Decouple in X.Xs" / "Ignition in X.Xs" alerts at the top of the screen during a delayed stage so you can tell what is about to happen.
- Already-active engines (e.g. the launch engine that just ran out) no longer go into the ignition pending list, so the cascade fires the next decoupler immediately instead of waiting the engine delay for a no-op.
- Synchronous IActivate buffer drain so VehicleConfig sees the new IsActive state right away and Auto burns stay armable across consecutive stagings.
- Code polish

Tested against KSA v2026.4.17.4184.

I decided to also upload the mod to SpaceDock: https://spacedock.info/mod/4254/AutoStage

 

[Maxi]

To run AutoStage on KSA 2026.5.7.4397 or newer you need at least AutoStage v0.3.4.

KSA 2026.5.7.4397 reworked how decoupling integrates with the vehicle update task.
If you try to use the new KSA version with earlier builds of this mod it will crash the game with InvalidOperationException: Collection was modified the moment a stage decouples.
