# BezierCurve:evaluate

Available since LÖVE 0.9.0
This function is not supported in earlier versions.

Evaluate Bézier curve at parameter t. The parameter must be between 0 and 1 (inclusive).

This function can be used to move objects along paths or tween parameters. However it should not be used to render the curve, see BezierCurve:render for that purpose.
