Beginner LUA question

[Pants]

Just starting to learn LUA scripting, thanks to Aggrors tutorials.

 

Is it possible to pick an object and have the object execute a function? Can I camera pick a door, and have the door run it's own object:open() method? And if so, how? I know this can be done using SendMessage and ReceiveMessage, but I need to pass more variables than those will allow (lua types, to be specific).

 

Thanks.

Look at how the switch and underground_fanblades scripts work. Also open up the tunnels.sbx file and you will see an example of them working.

As far as I can tell, this example uses messages..

Hi, you can use something like this

require("scripts/utilities")
...
local pick=CameraPick(fw.main.camera,Vec3(GraphicsWidth()/2,GraphicsHeight()/2,2.0),0,0)
if pick then
    local pickedmodel=GetMeshModel(pick.entity)
    objecttable[pickedmodel]:open()
end

I am working on tutorials that cover objects scripts. One of the topics is sending messages and camera picking.

 

What kind of parameters do you want to add to your function?

Thanks Soamp, that works perfectly!

I'm not sure how the objecttable works, but I'm sure I'll learn.

 

 

Aggror, the door:open() was an example just to illustrate my problem. To be specific, if my player character is punching another character, so I need to pick the enemy, and have it run a GetHit() function, the parameter passed needs to be a Lua type holding my character object's rpg-style skill variables, like player.attribute_strength, player.skill_unarmed, and so forth. The problem I was having is that you can not pass lua types as the extra parameter in SendMessage, all it allows is the message, delay, and an extra string.

 

The solution Soamp suggested is exactly what I needed, thanks again.

sorry for the misdirect, I didn't understand exactly what you were trying to accomplish...

 

but in any case, you should probably read Getting Started with Lua... specifically page 10 concerning Classes and Objects.
