Calculating jumplength based on x and y only

FiveM Resource Development & Modding Discussion

Heya folks!

I found this bit of code that attempts to detect a superjump. The issue with this is that it counts (z) height into it’s jump length so if someone falls off of a building, it considers that a superjump.

Is there a way in which I could modify this to only consider x and y to determine whether a superjump has occurred? I’m failing miserably and handling it. In my head, it makes sense that I’d want to grab the player coords and do some magical math based on the two points but I lose the plot at that point and have been unable to sort out a working example.

--[[ SUPERJUMP CHECK ]]--
Citizen.CreateThread(function()
	while true do
		Citizen.Wait(0)
		if (AntiCheat == true and whitelisted == false and whiteCheck == false)then
			if IsPedJumping(PlayerPedId()) then
				local jumplength = 0
				repeat
				Wait(0)
				jumplength=jumplength+1
				local isStillJumping = IsPedJumping(PlayerPedId())
				until not isStillJumping
				if jumplength > 200 then
					TriggerServerEvent('AntiCheat:Jump', jumplength )
				end
			end
		end
	end
end)

Get the coordinates at the beginning of the jump and then at the end of the jump. Then check the distance using x and y only.

Sorry, I’m bad at math. If someone is jumping diagonally, would I simply x+y? Is there some kind of radius deal I would need to chew on to get it right?

I seem to be failing at integrating the native. No jumps trigger it. My effort tries to set the last nonjump pos , getting the last isjump pos, then comparing the two with the native.

--[[ SUPERJUMP CHECK ]]--
Citizen.CreateThread(function()
	while true do
		Citizen.Wait(0)
		if (AntiCheat == true and whitelisted == false and whiteCheck == false)then
			if not IsPedJumping(PlayerPedId()) then
				notjump = GetEntityCoords(GetPlayerPed(-1))
			elseif IsPedJumping(PlayerPedId()) then
				
				local isStillJumping = IsPedJumping(PlayerPedId())
				local isjump = GetEntityCoords(GetPlayerPed(-1))
				
				until not isStillJumping
				print('isjump: ',ESX.DumpTable(isjump))
				if GetDistanceBetweenCoords(notjump, isjump, false) < 5 then
					print('You triggered superjump')
					--TriggerServerEvent('AntiCheat:Jump', jumplength )
				end
			end
		end
	end
end)

If I try dumping the isjump table, it’s nil.

while true do
    Wait(0)
    if IsPedJumping(PlayerPedId()) then
        local firstCoord = ...
        while IsPedJumping () do
            Wait (0)
        end
        local secondCoords = ...
        local distance = ...
        if distance > 10.0 then
            ...
        end 
end

I guess doing so may work. Can’t help much I’m on phone (you will have to fill the code but I hope you get the idea).

That seems to have done the trick:

Citizen.CreateThread(function()
	while true do
		Wait(0)
		if (AntiCheat == true and whitelisted == false and whiteCheck == false) then
			if IsPedJumping(PlayerPedId()) then
				local firstCoord = GetEntityCoords(GetPlayerPed(-1))
				while IsPedJumping(PlayerPedId()) do
					Wait (0)
				end
				local secondCoord = GetEntityCoords(GetPlayerPed(-1))
				local jumplength = GetDistanceBetweenCoords(firstCoord, secondCoord, false)
				if jumplength > 10.0 then
					print('You triggered superjump')
					TriggerServerEvent('AntiCheat:Jump', jumplength )
				end
			end
		end
	end
end)

Thanks so much for the help!
