Flowgraph and functions arguments

[Marcousik]

I found this function in the FPSPlayer.lua

--Increase health
function Script:ReceiveHealth(healthPoints)--in

    --Increase health
    self.health = self.health + healthPoints;

    --Health can not be more then maximum health
    if self.health > self.maxHealth then
        self.health = self.maxHealth
    end
    
    --Call Health received output
    self.component:CallOutputs("HealthReceived")
end
 

I can call this function through the flowgraph using the output Function (example calling the function self:Heal(10) ) of another script but it returns an error about the argument "healthPoints" as nil value, whatever I give as argument.

function Script:Heal(healthPoints)--out
    self.component:CallOutputs("Healing")
end

What am I doing wrong ? thx for help

Notice how the function has --in at the end. That tell the editor it can be called. When --in functions exist with parameters you need a function that has --args and returns a value (I believe is the name) and then that'll show up and you can drag that function to the dot that should show up in the flowgraph on the line of the ReceiveHealth() function. So dots show up on that line and they act as argument placeholders (1 for each argument). When you drag a --args function to that line, that function will be called and the returning value will act as the argument value.

THX Rick. A tutorial on this may be a very cool thing
