I am making a crane that can be extended/retracted, but I want to limit how much it can be extended/retracted, so the tubes wont fall out of it’s parent tube, please let me know how to do so.
I have attached my blueprint on how to control the extension of the tubes, its a stupid method that I came up with, feel free to correct me if there are simpler and better way to do that as well, thanks a lot.
Why not use set local offset and use a clamp node?
Might work. Counterquestion to you: what if a component is driven by force, not by functions? Is there a way to limit its movement other than by putting a blocking volume where it should stop?
BTW, @jasoncwf, you can create blocking volumes one for each tube, and tick the sweep box when offsetting. It will require setting different collision presets for different tubes.
You could add a conditional branch, and check if the offset is less of the max-offset value then the crane extends when the user gives the input, otherwise if the crane offset is >= of the max-offset value then nothing happens.
You could use variables to set these values or just use float/int nodes.
Edit: I’ve posted this before my first comment, but it went through moderation queue and appeared only now, so sorry for double. But I think I can leave this as an answer too.
The best solution depends on the rest of your system, but the first thing you can try is to use the [Clamp][1] node before the Delta Location Z inputs:
This way you can limit your offset for both negative and positive values, using the Min/Max inputs.
For the forces you can look at physics constraints. They allow you to set linear offset limits.
Thank you. That really did the job limiting a component’s movement.
Thank you very much, I will give it a try when I have the chance
