Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Get Center of mass with excution pin

Hi everyone ,

I'm following Zak parrish"s tutorial about making a Ball puzzle : https://www.youtube.com/watch?v=d7JKfbk699Q .

i succeeded to copy every step of the tutorial , except for one node that i can't find the same as he's using which is " Get center of mass " that has an execution wire (Bottom picture attached) ,

i mean in my blueprint editor i can just find either "Get center of mass" that does not have an execution wire ,Or a "Set center mass" (Top picture attached) , i'm using the latest version 4.19 .

So how can i make a " Get center of mass " node with an execution wire as shown from Zak's tutorial (Bottom picture attached) ???

,this is stopping me from adding the same node , exactly at minute 58:13 of that tutorial ( https://www.youtube.com/watch?v=d7JKfbk699Q ) .

Thank you for the support.

Insted of coping you should learn how blueprint works, because whatever node has execution pins or not makes not much difference, point is to get center of the mass and both nodes will give you same result. Fact that he had execution pins could potentially is a bug because all get nodes should optimally be pure nodes. You would not think of what type of node it is if you would not think only about coping the circuit.

Pure nodes (green once without exec pin) are executed when needed by things they are plugged to, so if you plug in to other node with execution pins it will execute it. So plug next node in order to event and plug rest of center of mass pins where they should and circuit will work the same.

If you really want to 100% emulate behavior of node with execution pin, make a function with local varable and set local variable from pure node and return local variable in function, but this is pointless if you ask me

Hi,

Thanks for your help , one more question is all the green nodes a function that do not have execution pins like regular functions .
