Hydros using a hotkey?

I've been experimenting with hydros following this tutorial, and the only way I can get them to work is using the key for steering the wheels. Does anyone know how to make hydros activate when I press a specific key, like how "O" opens the tailgate on the D-series? I'd also like to know how to make the hotkey toggle the hydros, instead of them just retracting as soon as I take my hand off the key.

 

Thanks!

 

I followed the tutorials as best as I could, but I still couldn't get the hydros to extend. The "controls" panel appears in the top right, though. I'm trying to get the tailgate of the roamer to open, do you think you could help?

Spoiler: files

file structure:


input_actions_opentailgate.json:


The hydros: (I changed the beam strength from 32000 to 1000 on the latch of the tailgate to make it open easier, but the tailgate just pops open when I spawn the car. Should I put it back to 32000?)


inputmaps folder:

I know the slots are working correctly on the tailgate, though.

EDIT: nevermind. whatever it was, I just copied the pickup's hydros into mine and it worked fine.

 

Oh, I see.
