Lerpable

from tdw.lerp.lerpable import Lerpable

A value of type T that can be linearly interpolated between minimum and maximum values.

Fields

value The current value.
is_at_target If True, self.value is at its target (the minimum if increasing, the maximum if decreasing).

Lerpable(value)

Parameter	Type	Default	Description
value	T		The initial value.

self.update()

Interpolate. If we're done interpolating, stop.

This will set self.value to a value between the minimum and maximum.

self.set_target(target, dt)

Set a new target for self.value.

One end of the line between a and b will be self.value and the other will be target.

Parameter	Type	Default	Description
target	T		The target value.
dt	float		The true value delta per `update()` call. For example, if this is a position and you want move the position by 0.1 meters per `update()` call, then this value should be 0.1.

self.get_dt()

Returns: The signed change in value.
