Cold Sweat: Altitude
Cold Sweat: Altitude is a configurable addon for Cold Sweat that adds temperature changes based on altitude.
Create warm cave layers, neutral surface conditions, freezing mountain peaks, or dangerous upper atmospheres entirely through config.
Requires Cold Sweat 2.4.1 or newer.
Features
- Fully configurable altitude bands with min/max Y ranges
- Smooth temperature transitions between bands
- Additive or multiplicative temperature modifiers
- Dimension whitelist and blacklist support
- Priority-based band resolution
- Shelter-based reduction of altitude effects
- Item-tag-based protection for pack makers
- Coloured action-bar feedback when changing altitude bands
- Create: Aeronautics / Sable ship shelter and heat-source compatibility
- Runtime commands for inspection and debugging
Smooth altitude gradients
Choose how temperature changes between altitude bands:
NONE- temperature changes instantly at each band boundary.LINEAR- temperature changes gradually across the whole band.BOUNDARY- temperature remains stable through most of the band and transitions smoothly near its edges.
Action-bar feedback
Entering a new altitude band displays a coloured action-bar message:
- Warm bands tint red
- Neutral bands remain white
- Cold bands tint blue
Use actionbarDisplayTicks to control how long each message remains visible.
Create: Aeronautics / Sable support
When Create: Aeronautics and Sable are installed, Cold Sweat: Altitude supports altitude, shelter, and heat sources on assembled ships.
Ship interiors can use shelter protection, while Aeronautics burners and steam vents contribute heat in both normal world spaces and Sable contraptions.
