Hi

how to define global variable where all kilobots robots scripts can see this variable in V-REP?

thanks in advance.

Hello,

you have several possibilities. Simplest is to define an integer, float or string signal:

• sim.setIntegerSignal
• sim.setFloatSignal
• sim.setStringSignal

Using a string signal you can basically convey or share any type of data, for instance:

Code: Select all

local myDataStructure={}
myDataStructure.id=42
myDataStructure.data={1,2,"Hello"}
sim.setStringSignal("myStringSignal",sim.packTable(myDataStructure))

Cheers

Excuse me, can you give me an example, please? or where can I write the global variable that allow all kilobots child scripts see it?

e.g. if you want to share a floating value, you would write and read that variable with:

Code: Select all

-- write:
sim.setFloatSignal("myFloatSignal",value)

-- read:
local value=sim.getFloatSignal("myFloatSignal")

Cheers
