Flocks

1.3 restructures the plugin to be much more simple to
work with internally. I would only recommend updating if you are
not using many blueprint nodes as these may need to be recreated
(this is a one-time deal).

New to Flocks 1.3:

Completely rebuilt the plugin from the ground up to better
support parallelism and GPU shaders. Updates are much easier to
implement. Algorithm should now be more efficient, and have a
reduced memory footprint.

MAC SUPPORT! The plugin will now run correctly
in METAL.

Description:

Simulating huge amounts of Boids in optimal frame rates has
never been easier than it is with Flocks.
Supporting a massive 65000+ agents at runtime, and
with a large array of modifiable values, you can create life-like
flocks with no effort at all. With built-in support for Restriction
Volumes, you can easily define areas that are off-limits – or use
Goal/Flee Volumes to make flocks that dynamically react and run
away from predators!

Flocks allow you to modify every aspect of the
simulation at runtime – change values for Cohesion, Separation,
Alignment, Speed, Scale – and many more. Define groups that have
different meshes/settings and change how they interact with each
other at the flick of a switch.

Despite running on a complex optimized code algorithm, Flocks
comes with full Blueprint Support which boasts a heavy focus on
ease-of-use. Changing the scale of one agent, or randomizing the
speed of every agent is as easy as calling a single function in
Blueprints!

Changelist:

New to Flocks Version 1.1:

Animation support! Simple VAT animations can
now be applied to the simulation – these can be built directly from
a skeletal animation in the editor. Add more life to your world,
simulate birds, butterflies, insects and more. With the power of
Vertex Animated Textures, you can easily run
20,000+ animated meshes in 60FPS.

New to Flocks Version 1.2:

Added Interaction + Health Support! You can now
line trace for boids, allowing developers to use them for
interactive gameplay! Add raycasting weapons that can damage boids
and increase the immersion of your games.
