Function on MarkerHit

[Bonsai]

Hey all,

I got another little problem, and I can't solve it by Wiki.

I want a function to start its job, when a Player hits a marker.

local level = 0 
  
function drainSomeWater() 
    level = level - 0.01 
    setWaterLevel ( level ) 
end 
setTimer ( drainSomeWater, 100, 15000 ) 

For example, that function triggered on Marker Hit.

SetTimer is used here, to make the water go down slowly.

So actually, I just need the Timer to start on Marker Hit.

But I can't get it working.

I hope someone understands the Problem, and knows how to fix it.

Greetings

Put setTimer into a function which is attached to onMarkerHit event.

local level = 0 
addEventHandler("onMarkerHit", getRootElement(), 
    setTimer ( drainSomeWater, 100, 15000 ) 
) 
function drainSomeWater() 
level = level - 0.01 
 setWaterLevel ( level ) 
end 

try this

local level = 0 
[b]addEventHandler("onMarkerHit", getRootElement(), 
    setTimer ( drainSomeWater, 100, 15000 ) 
)[/b] 
function drainSomeWater() 
level = level - 0.01 
 setWaterLevel ( level ) 
end 

try this

I think you need a function for that.

addEventHandler("onMarkerHit", getRootElement(), 
function(element) 
[b]if getElementType(element) == "player" then[/b] 
    setTimer ( drainSomeWater, 100, 15000 ) 
end 
end 
)

Nice one, works perfect.

I don't really understand why it has to look like this, but anyway, Works!

Thanks

What exactly you don't uderstand?

We can try to explain it to you - becouse if you won't understand it now - you will return with same question soon or later

[Zango]

  
addEventHandler("onMarkerHit", getRootElement(), 
function(element) 
if getElementType(element) == "player" then 
    setTimer ( drainSomeWater, 100, 15000 ) 
end 
end 
) 
  

Is the same as

  
function functionName (element) 
if getElementType(element) == "player" then 
    setTimer ( drainSomeWater, 100, 15000 ) 
end 
end 
addEventHandler("onMarkerHit", getRootElement(), markerHit) 
  

but it's just an alternative way to put it.

Riiight, I made it too quick to even notice that

[Bonsai]

addEventHandler("onMarkerHit", getRootElement(), 
function(element) 
if getElementType(element) == "player" then 
    setTimer ( drainSomeWater, 100, 15000 ) 
end 
end 
) 

Why does this function have to be in there?

I tried to do the same by just putting the function's name in there, but it didn't work.

So I'm a bit confused here.

addEventHandler("onMarkerHit", getRootElement(),        [color=#BF0000]--This event is triggered when an element enters a marker created using createMarker. [/color] 
function(element) 
    if getElementType(element) == "player" then        [color=#BF0000] --if the element that entered the marker was a PLAYER [/color] 
        setTimer ( drainSomeWater, 100, 15000 )         [color=#BF0000]--then this little timer will activate the function we called "drainSomeWater" like this:[/color] 
    end                                                [color=#BF0000] --Every 100 milliseconds, the function drainSomeWater will be repeated. It will be repeated 15000 times.[/color] 
end 
) 
level = 0   [color=#BF0000]--as you should know, sea level is 0 (geography)[/color] 
function drainSomeWater() 
    level = level - 0.01    -[color=#BF0000]-once we've entered the function in which setTimer threw us in, we'll decrease the level of the sea[/color] 
    setWaterLevel ( level )  [color=#BF0000]--the actual size is set now[/color] 
                            -[color=#BF0000]-at first it only loses 0.01 of the size, but remember that it gets repeated 15000 times so hence we have total sea drown[/color] 
end

I know how that function words.

Its just, I tried to do the same before I posted here.

I created a function with a Timer in it, and set it to trigger on(Client)MarkerHit.

addEventHandler("onMarkerHit", getRootElement(),  functionWithTimerInIt) 

functionWithTimerInIt() 
  
 setTimer ( drainSomeWater, 100, 15000) 
  
end 

And that did not work.

But now, everything works fine using the other way

Thx again.

[Zango]

functionWithTimerInIt() 

Isn't valid, you have to separate function with the name.

You declare a function 'WithTimerInIt' but when you do not separate those, how is LUA supposed to know you do so.

function WithTimerInIt()

function WithTimerInIt() 

Woopsi, just a misspelling

[norby89]

Don't forget you have to declare the function before the handler, else it won't work.

Okay, Another problem

addEventHandler("onClientMarkerHit", grav3, 
function(element) 
if getElementType(element) == "player" then 
    setTimer ( drainSomeWater, 100, 15000 ) 
end 
end 
) 

function drainSomeWater() 
  
level = level - 0.03 
setWaterLevel ( level ) 
destroyElement(grav3) 
  
  
end 

This works now. But it triggers for every Player.

How can I make it just for the Player who hits the marker?

Actually I know how to, but here, it doesnt work here.

function drainSomeWater(thePlayer,dimension) 
  
if (dimension and thePlayer==getLocalPlayer()) 
level = level - 0.03 
setWaterLevel ( level ) 
destroyElement(grav3) 
  
end 
  
end 

[BinSlayer1]

  
addEventHandler("onClientMarkerHit", getRootElement(), 
function(hitPlayer, matchingDimension) 
            setTimer ( drainSomeWater, 100, 15000 ) 
end 
) 
function drainSomeWater() 
level = level - 0.03 
setWaterLevel ( level ) 
end 

dont forget to use type="client" in meta.xml to run it client side

[Bonsai]

[lua]

Of course

But still doesn't work.

Add source to your setTimer call and leave drainSomeWater as

function drainSomeWater(thePlayer) 

... Read wiki carefully. Check setTimer parameters on wiki.

I tried that now, I'm not sure if I did it correctly, but it didn't work.

The Water was going down for everybody, not just for the MarkerHit Player.

addEventHandler("onClientMarkerHit", grav1, function(element) if getElementType(element) == "player" then 
    setTimer ( drainSomeWater, 100, 200, thePlayer==getLocalPlayer() ) 
end 
end 
) 

function drainSomeWater(thePlayer) 
  
level = level - 0.03 
setWaterLevel ( level ) 
destroyElement(grav1) 
  
end 

I can't believe that its so difficult to get it working

[50p]

Oh wait, it's client-side. You don't need to pass source to setTimer but you have to learn Lua a bit more..

Just do this for your onClientMarkerHit event:

addEventHandler( "onClientMarkerHit", grav1, 
   function( thePlayer ) 
      if thePlayer == getLocalPlayer( ) then 
         setTimer ( drainSomeWater, 100, 200 ) 
      end 
   end 
) 

In your case you don't need to check if thePlayer is actually player element because it'll be either player or vehicle element that hits the marker. Since they are both elements (userdata type) there will be no warning/error messages due to comparing different data types. Remember, grav1 has to hold a marker before you add the handler function.

Thanks a lot.

It works, finally.

Now I can finally finish this confusing map

Thanks.
