I am completely new to using Unreal Engine 4; please bear with me if I am not familiar with how this works quite yet, as I am learning some new skills. I used to do some projects a few years before with Unity, but for this university project I’m working on as part of finishing my bachelor’s degree, I chose UE4 because it delivers photorealism and offers a nice opportunity for me to practice C++ programming.
Anyway, I’m building, on an agile basis, a scenario generator for a student design team at my university on autonomous vehicles.
I have a simple plane here, with no textures applied to it, that I would like to scale while the application is running.
To start out, I want to use a slider placed at the top left corner to adjust the length of this “basic, transparent road.” This is done by adjusting the scale of the plane on the X axis; for now, just between 10 to 100 meters. The UI blueprint looks like this:
Right now, I need to add an OnValueChanged event listener so that when I move the slider back and forth from left to right, it sets a new scale value for the X axis of the plane. What I don’t know yet are what nodes I need to use in order to get the plane’s current scale, as a vector, set the X axis independently, then reassign it back to the actor. This is my blueprint so far:
All it does is it only takes the value of the slider and transforms it to a value between 10 to 100.
Do you know what I need to do next? Any helpful documentation and lessons I could perhaps check out? UE4 looks much more complicated than Unity, but it really helps me with my skills as I’m new and keen to this.
