Are there any rag doll tutorials or any other info or help about making rag dolls with Corona? Did a search on the website but couldn’t find anything.
Thanks [import]uid: 48020 topic_id: 17983 reply_id: 317983[/import]
Not that I have seen, no - although this is a good suggestion for a tutorial.
I’ll have to keep in mind for a future Techority post

That’s awesome! Did you write that?

Hej,
no i didn’t i have found it in the forum …
I have just changed it to fit my needs…

Either way very cool stuff, I hadn’t seen it before.
Thanks very much for sharing!
Peach [import]uid: 52491 topic_id: 17983 reply_id: 68722[/import]
There was some talk on a much earlier thread. Here’s the address:
http://developer.anscamobile.com/forum/2010/10/29/new-corona-any-radgoll-examples
I’ve put the code up on Github:
https://github.com/MarkHenryC/RagDoll
Works on Mac; don’t know about Windows.
Hope it’s useful. [import]uid: 3953 topic_id: 17983 reply_id: 70298[/import]
Hi, I added this function into the ‘game’ template, and created a ragdoll with it:
local ragDoll1 = newRagdoll(50,50)
Just wondering, what do I need to do to it to change its rotation and / or apply force to it?
I tried:
ragDoll1.rotation = 20
– this changes the rotation, but its collision detection gets messed up, like the whole physics engine got rotated independent of the rest of the world
ragDoll1:applyForce(10,-20)
– this throws me an error: attempt to call method ‘applyForce’ (a nil value)
Sorry for the rookie questions!
G [import]uid: 146743 topic_id: 17983 reply_id: 113121[/import]
ragDoll1 is the group
you need to apply force on the body parts … troso or head or whatever.
