SetElasticity and SetSoftness functions? (Lua)

[whiterabbit]

I have a model of a sphere with a collision mesh imported into Leadwerks and I wanted to control how 'bouncy' it was. Did a google search and came across the functions SetElasticity and SetSoftness (seems like they were called SetBodyElasticity and SetBodySoftness in older versions).

 

The current docs don't mention these functions, or at least not on Entity, and when I try to call them they obviously don't exist. Does anyone know if they've been renamed, not available to Lua, removed for some reason?

 

Just a few things I found:

http://www.leadwerks.com/werkspace/topic/2546-balls/ (This has a Lua script that calls SetElasticity which makes me think it did exist at some point)

http://www.leadwerks.com/werkspace/page/Documentation/le2/_/command-reference/bodies/setbodyelasticity-r58 (Old docs)

http://www.leadwerks.com/werkspace/topic/4683-problem-with-collision-callback/ (C++ but calls SetElasticity)

It seems that those are older functions from LE 2. At the moment I do not believe such functions exist (at least for lua). I had a similar issue so I made a little script for my ball to make it bounce. It looked like this -

 

function Script:Collision(entity, position, normal, speed)

self.entity:AddForce(0,.25*speed,0) -- Add Global force to make the ball bounce upwards.

self.entity:AddForce(0,.25*speed,0,false) -- Add Local force to make the ball have a random bounce

end

Thanks, I thought that might be the case. I just didn't want to have to do it myself.

Although doing it manually doesn't give the ability to have less than normal bounce.

 

EDIT: Sorry for double post. I'm used to posts auto-merging together on another forum.

You could also mess with giving the ball a higher mass, adding more or less force in that script, or even changing your worlds gravity amount.

Yep, I'm already going to be doing those things in different situations so it's not really a simple option. Gravity is disabled on the world and the ball applies a force to itself to simulate gravity so I can change the direction of gravity (not sure if you can change the gravity direction for the entire world?). I'll try and work around it for now.
