Blendstores

Blendstores are a category of blendshape created by VMC-MC. They behave slightly differently from standard blendshapes, but occupy the same format.

Blendshapes are intended to continually output a value, typically read from some sensor. This makes them ideal for continual events or reading the status of something. They struggle, however, to meaningfully output instant events.

The blendstore is a special blendshape that can be used to read instant events.

Behaviour

Just like a regular blendshape, the blendstore is always outputting a value. But the blendstore remembers its previous output and has different components that affect its value.

• Initial value
  • The default value to output with no event triggered.
• Activation value
  • The blendstore will jump to this value after its event has been triggered.
• Duration
  • How long the blendstore will stay at its activation value until returning to the initial value.
  • This is measured as the number of times it outputs.
• Decay
  • After the duration has been exceeded, the outputted value will move by this amount towards the initial value.

Example

The vmc-mc:attack_living blendstore follows this lifecycle:

1. The blendstore is outputting 0.
2. You attack a mob.
3. The blendstore is triggered, it begins outputting its activation value of 1.
4. The blendstore will output 1 for the next 50 outputs (2.5 seconds, 1 output per Minecraft tick).
5. The 51st output will be 0.95, the 52nd output will be 0.9, the 53rd output will be 0.85, and so on.
6. The output of the blendstore eventually falls back to 0.

In this way, the blendstore is able to treat instant events as if they were continuous, and then output as a regular blendshape.
