[help] Detect player fall from bike

[LoPollo]

I wanted to know the ways to detect when a player falls from a bike.

After some research i found 2 ways to detect it (both are untested, errors may occur: that's only the concept):

addEventHandler( "onClientPlayerDamage", root, 
	function(attacker, weapon, bodypart, loss)
		if getElementType( attacker ) == "vehicle" then
			--thus player has fallen
		end
	end
)

but i'm not sure if falling from a motorbike/bike ALWAYS damage the player (or ped if with "onClientPedDamage")

and

addEventHandler("onClientVehicleCollision", root,
    function(theHitElement, force, bodypart, collisionX, collisionY, collisionZ, normalX, normalY, normalZ, hitElementForce, model)
        local isSourceEqualToTheVehOfThePlayer = true --check for the localPlayer or the player or the ped etc
        if isSourceEqualToTheVehOfThePlayer then
        	--the event is called Before the fall if i remember correctly
        	--so check if after the event (50ms) the checked player has his vehicle
        	setTimer( 
				function(thePlayer, theVehicle) 
					if not getPedOccupiedVehicle( thePlayer ) then
						--our player is not a good driver
					end
				end
			, 50, 1, getVehicleOccupant( source ), source )
        end
    end
)

but i'm not sure if it is 100% correct and i'm sure it's not a "clean" way to solve the problem.

So the answer is: do falling from a bike always cause damage? and are there other ways to achieve this i'm not aware of? (maybe i didn't found the event for this)

also sorry for any english error

I don't know if there is any other way to detect the fall but I know that fall from bike does not always cause damage.

So i will use the second concept.
Thank you for the information and the reply

When a player "exits" the bike, the event onClientVehicleStartExit never gets called. I tried this and it worked: 

local startExit = false

addEventHandler("onClientVehicleStartExit", root, function(p)

	if p == localPlayer then
		if getVehicleType(source) == "BMX" then
			startExit = true
		else
			startExit = false
		end
	end
	
end)

addEventHandler("onClientVehicleExit", root, function(p)

	if p == localPlayer then
		if getVehicleType(source) == "BMX" and not startExit then
			outputChatBox("you just fell off")
		end		
		startExit = false
	end
	
end)

Using onClientVehicleExit works! As you said it gets called when falling from the bike. Thanks for you help too!

[pa3ck]

Yes, it gets called when falling from a bike, but onClientVehicleStartExit isn't. So basically if someone exits the bike and onClientVehicleStartExit never got executed, you know that they fell of the bike (or it got destroyed etc).

Hey,

I have a problem related to this topic. I want to detect collision when bmx hits an object. The problem is that handler "onClientVehicleCollision" not always works. Any suggestions? I was thinking about processLineOfSight but maybe there is better solution, Thanks in advance.

What do you mean? The handler does not always detect collision, maybe with a particular kind of object? Do you think it could be a bug? I can't see any issue in the wiki page

Process line of sight require coordinates to work, how do you think you will get them?

It doesn't work on small jumps.

You attach the line near a player.

addEventHandler("onClientVehicleCollision", root,
	function(theHitElement, force, bodypart, collisionX, collisionY, collisionZ, normalX, normalY, normalZ, hitElementForce, model)
		if source == getPedOccupiedVehicle(localPlayer) then
			outputChatBox( "DBG ["..getTickCount().."]: Collision")
		end
	end
)

Using this function when i collide with my BMX with objects i always get the message in the chatbox. No matter if while jumping, falling etc. Tested with a BMX (lol) in Santa Maria Beach area. In the wiki page (i think when i am tired i am blind) there's this:

Issue ID	Description
#7422	onClientVehicleCollision doesnt trigger when hitting some frozen objects

But i do not think this related to your problem.
 

So this bring me to think that maybe there's a condition in your event that prevents some code to be executed. Could you post your handler function?

bad english

[2kristof2]

I was checking the collisions in exactly the same way. The handler doesn't trigger for example when I jump on an object with ID 3095. Anyway I don't really need this handler anymore. Thanks for your answer.

Thank you!!! This helped me so much!
