I am learning Unreal Engine since a past few days. So I bought a course on Udemy and the guy made a small project where we can make spheres shoot like projectiles. While watching the tutorial I just copied what he was doing but after the completion of the tutorial I thought of doing it again on my own this time. When I was trying to make the same project on my own I faced a problem which you can see it in the screenshot attached. In the number 2 screenshot, the “Spawn Actor” node is different than that of screenshot 1. Why’s that? And how can I fix that? I need the “Spawn Actor” node as number 2 but every time I search for “Spawn Actor” it just gives me the node as in number 1 screenshot. With this problem I can’t shoot projectiles in the direction I am pointing but only on the X axis.
is the same but using spliting pin
Hey there,
Those can be confusing at first. 
What you need to do here is split the pin, like this:
Basically any pin which enters of leaves a node and that contains one of the basic data (int,float,array,string,text,etc) can be broken down and recombine. Those are structures essentially, or collections of more basic variables.
A vector if just stored as three floats, same for rotators.
And a Transform is a collection of one vector for location, one rotator for rotation, and a second vector from scale, so 9 floats in total
Split and recombining a Pin is essentially the same as this, but done duirectly on the node.
Hope that helps, feel free to ask if you have more questions.
I didn’t know that one 
Seems related to the blueprint Friendly Name, this has always been causing trouble. It feels like the thing they did at first thinking it was a good idea but turned out to be a nightmare to maintain. Category for functions/variables are still completly broken because of this ^^
Notice the underscores if you have the friendly blueprint variable names disabled.
Lulz. What kind of sorcery is this even?!
thanks bro you are the g
