lua - 增加 math.random 的值

Question

嗨，我正在尝试每 60 秒将“setLinearVelocity”的值增加 10。

badclouts:setLinearVelocity(0, math.random(100, 150)) -- Drop down

local function setLinearVelocityTimer()
   LinearVelocityTimer= timer.performWithDelay( badclouts, setLinearVelocity, 0 )
   LinearVelocityTimer= setLinearVelocity +10
   --print("time1 " .. setLinearVelocity)
end

countdownTimer()
local mainTimer = timer.performWithDelay( 6000, setLinearVelocityTimer, 10 )

我已经尝试过了，但没有成功，非常感谢任何帮助。

问候凯文，

Answer 1

我认为您正在尝试这样做：

badclouts:setLinearVelocity(0, math.random(100, 150)) -- Drop down

local function increaseYVelocity()
   local vx, vy = badclouts:getLinearVelocity()
   vy = vy + 10
   badclouts:setLinearVelocity(vx, vy)
   --print("y component of linear velocity: " .. vy)
end

countdownTimer()  --I don't know nothing about this function

local mainTimer = timer.performWithDelay( 6000, increaseYVelocity, 10 )
