I have a flask in where I want it to spawn a water particle when the player holds it upside down. My problem is that i don’t know how to use the Get Actor Up Vector to trigger the particle to spawn.
This is what I’ve got so far.
The Up vector will be 0,0,-1 if the flask is exactly top down.
What you can do to trigger your branch is to add a Math / Equal (Vector) node in order to compare your actor up vector to the upside down vector which is 0,0,-1. Drag a branch from the return value of the “Get Actor Up Vector” node and type “==” this will show your the equal (Vector) node.
The equal node also have an “error tolerance” float so that it doesnt need to be perfectly vertically down in order to trigger.
Cheers!
