How to stop hydro from sagging under weight ? Example. Made hydraulic arm for lifting procedure on pick-up truck car carrier bed. When there is weight on the bed the hydraulic keeps sagging/bending back to original position. It should stop moving after i let my hand off the buttons to move the hydraulic. But it keeps moving or "rubber banding" if there is weight on it.
If it deforms permanently, you have to increase the beamDeform of the hydro. If it springs back into place, you should increase beamSpring. Keep in mind though that with higher beamSpring you might run into instability issues, in that case you will have to increase the weights of the nodes on the hydro ends.
Thank you. However I think in my case I believe I had the wrong input actions. Whattya think is the closest input action for KEEP DOING SOMETHING AS LONG AS BUTTON IS HELD ? The thing about hydros is the wrong input action and parameters makes it a million dollar event or a zero .
This is not possible to do via input actions alone. You will need a custom_input.lua file and call a function from it with onChange. Examples from the cannon prop: input_actions.json: Code: "liftUp" :{"order": 3, "onChange":"custom_input.liftBarrel( 0.5 * VALUE)", "title": "ui.inputActions.cannon.liftUp.title", "desc": "ui.inputActions.cannon.liftUp.description" }, "lowerDown":{"order": 4, "onChange":"custom_input.liftBarrel(-0.5 * VALUE)", "title": "ui.inputActions.cannon.lowerDown.title", "desc": "ui.inputActions.cannon.lowerDown.description" }, custom_input.lua (in a lua sub-folder of your vehicle folder): Code: -- This Source Code Form is subject to the terms of the bCDDL, v. 1.1. -- If a copy of the bCDDL was not distributed with this -- file, You can obtain one at http://beamng.com/bCDDL-1.1.txt local M = {} local function onReset() electrics.values['lifter'] = 0 electrics.values['lifter_input'] = 0 end local function updateGFX(dt) -- ms electrics.values['lifter'] = math.min(1, math.max(-0.0, (electrics.values['lifter'] + electrics.values['lifter_input'] * dt * 0.2))) end local function liftBarrel(value) electrics.values.lifter_input = value end -- public interface M.onInit = onReset M.onReset = onReset M.updateGFX = updateGFX M.liftBarrel = liftBarrel return M the liftBarrel function in this case is the most important one, it sets the electrics value for the lifter input. That value is then converted into your hydro control value in updateGFX. I won't go into detail of what exactly is going on there, this is needed for the lifter to also work on a controller device and not just keyboard.
Most excellent. Yeah I noticed in your tank creation since you were one of the makers you guys wrote a ton of lua. Looks like true functionality involves from us modders that we need to know lua. Blender and knowing what beamspring is is only like 10% LOL. BTW the input action is visible in my mod when I copy your liftbarrel example but does not work as the action itself. What should by hydro call to action name be ? -- "hydros": [ ["id1:","id2:"], {"beamSpring":"110000000","beamDamp":200}, //25 default {"beamDeform":"FLT_MAX","beamStrength":"FLT_MAX"}, {"beamPrecompression":1.0}, ["a11", "controlarm31",{"factor":1.0,"inputSource":"liftBarrel","inLimit":0.5,"outLimit":30,"inRate":0.2,"outRate":0.2,"inputFactor":1}], ["a8", "controlarm34",{"factor":1.0,"inputSource":"liftBarrel","inLimit":0.5,"outLimit":30,"inRate":0.2,"outRate":0.2,"inputFactor":1}], I've tried: liftBarrel lifter lifter_input custom_input lifeBarrel_input What drives me nuts is it appears in vehicle config as a control you can assign buttons but on click it doesn't work. Here's my input_actions file "controlarm_liftUp": {"order": 5, "onChange":"electrics.values.Controlarm = 1.0* VALUE", "title": "Lift Up CA", "desc": "Lifts controlarm" }, "controlarm_liftDown": {"order": 6, "onChange":"electrics.values.Controlarm = -1.0* VALUE", "title": "Lift Down CA", "desc": "Lifts controlarm down" }, "miniarmarm_liftUp": {"order": 7, "onChange":"electrics.values.miniarm = 1.0* VALUE", "title": "Lift Up MA", "desc": "Lifts Miniarm" }, "miniarmarm_liftDown": {"order": 8, "onChange":"electrics.values.miniarm = -1.0* VALUE", "title": "Lift Down MA", "desc": "Lifts Miniarm down" }, "controlarm_liftUp2" : {"order": 3, "onChange":"custom_input.liftBarrel( 0.5 * VALUE)", "title": "ui.inputActions.cannon.liftUp.title", "desc": "ui.inputActions.cannon.liftUp.description" }, "controlarm_lowerDown2": {"order": 4, "onChange":"custom_input.liftBarrel(-0.5 * VALUE)", "title": "ui.inputActions.cannon.lowerDown.title", "desc": "ui.inputActions.cannon.lowerDown.description" },
I did not write the lua for the tank, that was there before I worked on it already. The input source should be just lifter. If it's not working then something is wrong with your lua, check the console for errors.
How to set a default value for the lifter? Like.. After increasing or decreasing the value I want it to go back to its original position with a push of a button.
