TrueRotateLerpPercent(ExBPY, ExTP, ExTP)

Rotate between two parametrics (the magnitude of the resulting vector is the magnitude of the from vector), closing ratio fraction of the gap per second.
This function uses the last returned value as its rotation source, only sampling the source parametric once.

Declaration

public static ExTP TrueRotateLerpPercent(ExBPY ratio, ExTP from, ExTP to)

Parameters

Type	Name	Description
ExBPY	ratio	Fraction of gap to close per second
ExTP	from	Source parametric
ExTP	to	Target parametric

Returns

Type	Description
ExTP

Remarks

Ratio is not multiplicative as in RotateLerpPercent. Instead, it accumulates like the function 1-e^-rt. This means that the rotation is faster during the first second than the second second, and so on. Use TrueRotateLerpRate for constant rotation rates.

TrueRotateLerpRate(ExBPY, ExTP, ExTP)

Rotate between two parametrics (the magnitude of the resulting vector is the magnitude of the from vector), closing rate degrees of the gap per second.
This function uses the last returned value as its rotation source, only sampling the source parametric once.

Declaration

public static ExTP TrueRotateLerpRate(ExBPY rate, ExTP from, ExTP to)

Parameters

Type	Name	Description
ExBPY	rate	Degrees of gap to close per second
ExTP	from	Source parametric

VHome(ExBPY, ExTP)

Parameters

Type	Name	Description
ExBPY	speed	Speed
ExTP	location	Target location

Returns

Type	Description

Remarks

Use with StopSampling to home for only a few seconds.
This is primarily for use with non-rotational velocity. Rotational use creates: contracting spirals (0,90), circle around player [90], expanding spiral (90,180).
