# Enum ksCurve.EvalModes

Namespace: [KS.Reactor](/reactor/api-reference/ks.reactor.md)\
Assembly: KSCommon.dll

Affects how the keyframes are used when evaluating a curve.

```csharp
public enum ksCurve.EvalModes
```

## Fields

`Constant = 2`

Evaulate using the value of the keyframe that proceeds the evaluation time.

`Curve = 0`

Evaulate by solving the y component of the bezier curve defined by the key frames.

`Linear = 1`
