TFS 1.X+ [TFS 1.3] Which Condition to Use for Creature has Speed 0? Paralyze or Haste?

[Yan18]

Hi guys

I wanna do a creature has 0 speed for a specific time by condition, but I tried to use CONDITION_HASTE and CONDITION_PARALYZE, but it didn't work.

local speed = creature:getSpeed()

local condition = Condition(CONDITION_PARALYZE)
condition:setParameter(CONDITION_PARAM_TICKS, 10000)
condition:setFormula(0, -speed, 0, -speed)

creature:addCondition(condition)

What is wrong in the code?
