Ok for time, this is really obvious, external sync, no need to more explanations.
Looking at boxing, this is exactly what I don’t want, to add intermediate nodes everywhere.
If I write a node with a pin that can accept either a string or a value, then we should be able to directly connect string or value, no point of adding manual box nodes.
Attached is a small example of custom handler, that can accept several types, then node just decides what to do from it.
You can see it even accepts a bullet type (first node that I found by hand), but value/color are exceptions and it’s really a pain to add color wrappers everywhere.
About implicit cons, another attached example.
With cons you lose the connection status.
So idea is:
Input pin decides what it accepts, and how many (or other whatever rule).
Event is dispatched on connection (as it is now) (very important to capture event obviously)
Particle system accepts emitter/behaviour (unlimited amounts). No need for cons/group, as we also need to process some cooking on connection (instead of reprocessing the spread all the time, which is an absolute pain). Also order or connection is not important, as data structures and processing order is maintained within the system. (Actually it’s pretty much the same for any semi decent deferred renderer, can’t really use dataflow for that if you’re not on Titan X and want to have a bit of spare memory left ;)
Pin can accept a combination of ClassA, Class B (one of each), Or ClassC (mutually exclusive, so if ClassC is connected, we can’t connect ClassA). Also really useful (specially for custom pipeline links)
Why should even Add or Multiply node have multiple pins? Operation is commutative so just push all to it right away ;)
Going to inspector to change input count all the time is also a pain (also alternative, bit offtopic, please add a shortcut to increase/decrease input counts on those nodes, done that in my tool, took about 5 minutes to implement (and about an hour to register relevant nodes to it), one of the best time spent/productivity gain ratio I ever did (much easier and much better than auto add pins ;)
Hope that helps as a starter, if you need more elaboration let me know ;)
