Working on new scripting system.

Wacov

Is the delete command just '.delete'? Could you give us a breakdown of all the attributes/methods attached to the curEvalGroup class in the next version (assuming that's where '.position' now comes from). Oh, and I was wondering, how do you loop a block of code in Ruby, within a single frame, until the target is acheived?

CPhillips

You mean to delete a body? Its actually called "destroy". curEvalGroup will not be used in the new scripted field, its implied. Currently bodies have the following:

magnetic/solid/static/frozen
position/transformation
getVelocity/setVelocity
getTorque/setTorque
teleport
push
copy
destroy
connect/attach
split
setEvent

Body events are
onStart/onEnd
onTick
onKey,onButton,onMouse
onTouch,onTouching,onUnTouch

Loops could potentially hang Sketchup. What are you trying to do exactly?

Wacov

The pathfinding algorithm needs to run through a loop of a series of steps to find the path. The loop ends when the target is added to the closed list OR there are no Nodes left on the open list. I could always stick in a failsafe to carry it over to the next frame after a certain number of loops... be aware I'm not actually doing anything right now, I'm waiting for the next version . I've got plans that use the new features...

CPhillips

That doesnt sound like something you would want to do at runtime. Only when you actually move the nodes.

I think your node system will be easier with the new scripting system.

Wacov

I HAS to be at runtime... the basis of any AI system is dynamic pathfinding. It'll re-calculate a route every time the target changes... anyway, if it crashes, I'll try something else
This explains it better that I can: http://www.policyalmanac.org/games/aStarTutorial.htm

Quick question for Chris Phillips: I saw one of the videos that you posted, that demonstrated the new joint-connect script. As I recall, the connection looked much stronger than the current joint connections. Is this true?

CPhillips

I havent changed anything to make joints stronger. In fact I have been spending a bunch of time trying to figure out how to make a weaker kind of joint.

Wacov

Any news on release yet... nothing specific, but a couple of weeks? More that a month? Throw me a bone here

CPhillips

I am sorry, I really dont know at this point. I am making good progress but so much of it is unfinished and during the summer the amount of time I can spend on it is limited. I might setup a closed beta so that you guys can start testing some of the new scripting features.

Lately I am working on doing the scripting interface in wxSU instead of webdialogs. That should make it a lot simpler to add new features. Also I am going to add some settings to fixed joints to allow them to be "springy". Its hard to explain but kinda fun.

That's almost possible now; just move the joint fairly far away from the object that's attached to it.

Wacov

A closed beta would be great! I appreciate it's just you, working on this huge plugin... if it's done when it's done, that's fine by me

Physicsguy1

Chris, can you tell us the new features that will be in the next release?

CPhillips

Almost all of the new stuff is outlined in this thread. Mostly it is the new scripting system which should make a lot of new stuff possible.

Beyond that there is the ability to set object density and maybe adjustments to how stiff some joints are.

darkPhysics

Can we get SP3 X April 6 even if it's not done? I'm pretty sure many of us here would like to see new features. Please, CPhillips.

Physicsguy1

We can't pressure him too much. This is a big project. Besides, we won't be getting it soon, because he is probably still debugging and working out all the little errors. We would probably just have what we have now,and a few of the new features, but with a whole lot of problems.

CPhillips

Sigh, I guess a little pressure is warranted. Its been a while since a release. Ill work on an interim release but no promises.

Physicsguy1

Thank you! I'm guessing most of the features outlined in this topic will be in it.

I have a script problem.

results=UI.inputbox ["Drive Options"], [""], ["Motor|Thruster"], "Drive Options"
if results=["Motor"] then @@motor=1
end

. I can't figure it out. It might be related to Sketchyphysics. The motor that retrieves @@ motor will spin regardless of input. I can't control it!

You put 'if results=["motor"]. it should be ==, not =. When you put =, it sets @@motor to 1. if you change it to ==, it will work properly.

Physicsguy1

results=UI.inputbox ["Drive Options"], [""], ["Motor|Thruster"], "Drive Options"
if results=="Motor" then @@motor=1;end
if results=="Thruster" then @@thruster=1;end
Still won't work.
