Drip Line Reference

This component creates a puddle which realistically expands and contracts over time.

Methods And Properties

float Rate { get; set; }

This property sets the rate of change per second of the wetness level. 0 is completely dry and 1 is completely wet; set this property to 1 / T where T is how many seconds you expect the puddle to take to be completely wet.

BeginRaining()

Call this to begin the raining phase of the puddle. The puddle will grow at the rate defined by the Rate property.

BeginDrying()

Call this to begin the drying phase of the puddle. The puddle will shrink at the rate defined by the Rate property.

Editor Preview

Auto Play

When this box is checked the puddle will automatically animate from Wet to dry in an endless loop (only when selected and in edit mode).

Rain

When this button is clicked the puddle will begin it's rain cycle, once it is fully wet the animation will end and it will remain fully wet (only when selected and in edit mode).

Dry

When this button is clicked the puddle will begin it's drying cycle, once it is fully dry the animation will end and it will remain fully dry (only when selected and in edit mode).

Wetness Source

A reference to a Wetness Source component.

Decal Prefab

A prefab which contains a Wet Decal component. Instances of this prefab will be created by the puddle component.

Wet State/Dry State

These sections define the two "end points" of the puddle animation. The Wet State defines the state that the puddle is in when it has finished the animation and is completely wet. The Dry State defines the state that the puddle is in when it has finished the animation and is completely dry.

All the settings are the standard settings for a Wet Decal.

Raining Curves/Drying Curves

These sections define the curves the puddle follows when animating between wet and dry. The Raining Curves define the curves used when getting wetter. The Drying Curves define the curves used when getting drier.

For every curve the X axis is the wetness (0 to 1) and the Y axis is between the dry state and the wet state.

Retire Fadeout

When a new raining animation is begun (by calling BeginRaining) all the existing puddle instances controlled by this component are "retired", they will fade out over a period of time and a new puddle instance will play the new raining animation. The Retire Fadeout curves determines how the fadeout of retired puddles progresses over time.
