Insite into how to use new system of lua scripts

[Jim]

Could someone give me more detail instructions on how to get the lua scripts attached with the entity so they work together. The old way was to attach the scripts to the entity but now you can only attach one script. If you have several scripts that you want to effect that entity, how do you do this under the new system so that they will be recognized and interact. By that I mean you can call the functions and the variables in other scripts and they are recognized.

[Rick]

Not sure what you mean. You can attach more than 1 script to an entity as far as I know. Also as far as I know you access the other scripts by their name off the entity variable like entity.scriptname:function(). Note I think scriptname has to be all lowercase to work.

It has changed :

- Select your entity

- in the panel of bottom panels (general, appearence,physics) , you have now a tab by default named "script"

- go to that tab and choose a script

You can't no more choose several scripts per entity.

So that's what Josh meant when he sent me an IM asking how I liked the single entity system. Why in the world was that changed? Doesn't that sort of screw up scripts like the animation manager which does 1 task and does it well, while still allowing us to attach other functionality to entities?

 

That also screws up the flowgraph scripts like http://www.leadwerks.com/werkspace/files/file/430-next-level/. *sigh*

 

 

Was there an explanation somewhere for why that changed?

Check the blog: http://www.leadwerks.com/werkspace/blog/41/entry-1081-leadwerks-3-update-available/

What you do know is attach one script then include other scripts from that one for example I attach a player script and the top line of that is

require "Scripts/Animation/AnimationManager.lua"

check the Darkness Awaits scripts.

I'm not at home but I assume that script is reworked then to not have the Start()/Update() functions like the entities did? If so, is it like a class and we have to make the object, or just turned to functions and global variables defined in it?

 

This is a bummer for component design Component design needs a way to link the components (and this is the game specific code) so that each component can be unaware of other components. Doesn't sound like that was being done and instead the linking was happening right inside each component, which if that was the route of course doesn't make a ton of sense, but oh well. The flowgraph still eixsts so that's still a win for components.

I have done this and it appears that the require lua script command does not run the script so the Script:Start() function is not run and some things are not initiated on start.

[josk]

Yeah the Animation script has been redone without a Start() etc.

 

As well as the require I think all that needed adding to the Start() of your entity code was

self.animationmanager = AnimationManager:Create(self.entity)

 

Also in your code where it would have said

self.entity.animationmanager:SetAnimationSequence(self.sequence.idle,0.05,200)

replace any self.entity with self.

 

I have yet to look at flowgraphs but they do look intresting and I imagine i will use them a lot.

I wonder if Aggror has done a tutorial

[AggrorJorn]

I have a tutorial on the lua flowgraph but it is completely useless now.

I am holding back on a new tutorial for now until it is a little more clear what the new system does for us. Don't get me wrong, I want to make a video about it, but the new system confuses me in its approach.
