Using the above blueprint, I have a SM_ChamferCube mesh in my scene and when I press K or M, it lifts it up or down in the air (physics is turned on so that it falls once you stop pressing K).
What I’m noticing is that when I start the scene, it constantly moves/jitters even when I’m not pressing K or M.
Any ideas as to why this is happening and how to fix it so that it just acts as a normal cube with physics when I’m not pressing K or M?
It’s too small to read. Why not keep physics turned off until you need it?
By what I can see the forward vector will be changing between 0-1 on all axis’ due to it having physics turned on. I’d anticipate that your cube isn’t stationary at the start which gives it its jittering value.
Try multiplying the entire Get Forward Vector times the axis value then add the z value multiplier afterwards. This way if there is no input then the vector returned should always be 0. Use a print string on what you input into the Add Relative Location vector pin to see if you are inputting 0 before you do your K and M input keys.
Hi there @August_Rosedale. Hope you’re well!
