Lua Make player/creature cant move

[Ruan Sebast]

Theres any way to i make that for some seconds? or any spell that make player paralyzed(cant move) for 10seconds.

Change their speed to 0, use addEvent() to change it back 10 seconds later.

function onCastSpell(cid, var)

       
        local function Func()
    
        local Spee = getCreatureSpeed(cid)
        doChangeSpeed(cid, - 900)
        end

        addEvent(Func, 900, nil)
        doChangeSpeed(cid, Spee)
    
    return doCombat(cid, combat, var)
end

I cant move now, but how i add my speed to normal after some time?

 

[Evan]

function onCastSpell(cid, var)
    local speed = getCreatureSpeed(cid)

    doChangeSpeed(cid, -speed)
    addEvent(doChangeSpeed, 10000, cid, speed)
 
    return doCombat(cid, combat, var)
end

Evan you could explain me , whats (cid, combat, var) and when i should use they?

 

[Evan]

They are arguments for the doCombat() function.
cid is the creature id of the creature that casts the spell.
combat is the combat object to use.
var is the variant in which the spell is involved in

You know any tutorial, or guides for beginners?

Feel free to explore around here: http://otland.net/forums/programming-scripting.481/
Generally, the best way to learn is to learn by examples.

 

[Ruan Sebast]

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_ENERGYAREA)
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)

function onGetFormulaValues(player, level, maglevel)
    min = -((level / 5) + (maglevel * 1.4) + 8)
    max = -((level / 5) + (maglevel * 2.2) + 14)
    return min, max
end

combat:setCallback(CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

function onCastSpell(cid, var)
    local speed = getCreatureSpeed(cid)

    doChangeSpeed(cid, -speed)
    addEvent(doChangeSpeed, 10000, cid, speed)

    return doCombat(cid, combat, var)
end

Giving that error when i cast the spell ._.

function onCastSpell(creature, var)
    local speed = creature:getSpeed()

    creature:changeSpeed(-speed)
    addEvent(function (id, speed)
        local creature = Creature(id)
        if not creature then
            return true
        end

        creature:changeSpeed(speed)
    end, 10000, creature:getId(), speed)

    return combat:execute(creature, var)
end

I was trying use
"getCreatureSpeed(cid)" for hours
F###

I look here: http://otland.net/threads/tfs-1-0-lua-functions.197202/
And here: https://github.com/otland/forgottenserver/blob/master/data/compat.lua#L747-754

And was getCreatureSpeed(cid)

@Ninja Where you search the correct way to use the functions?

You can use compat.lua as example to change TFS 0.2 functions to TFS 1.0/1.1 functions.
If you don't have compat.lua in your datapack or if it's not loaded (by global.lua) then all these 0.2 functions in compat.lua will still be a nil value.

You can find the all TFS 1.0/1.1 functions in luascript.cpp.
