Set by ref var doesnt work with C++ variables?

[playwithmewerder (Exp)]

Im trying to set my values like that, but for some reason only blueprint vars are getting set

It’s not the by-ref specifically; i sense it’s the Select node acting up. Does it work if you set it directly?

welp select does work with blueprints variables at least… first time facing this issue

[playwithmewerder (Exp)]

It does yeah

Right until you use a null object ref. In the past, it would just crash. But you’re right, it does work with BPs vars, indeed.

So C++ var does not enjoy being piped through the Select node?

I found the solution. Blueprints automatically convert float variables into doubles. If you connect a C++ variable to a select node for the first time, the output will be a ref of FLOAT type, so set by ref will be a FLOAT type as well, and will NOT set your blueprint vars. But when you connect a blueprint var first, the output of the select node will be DOUBLE, and set by ref will be DOUBLE as well, and it will NOT set your C++ vars.

Be careful, all the vars must be the exact same type, otherwise this wont work.
