Can't get out of a loop in a function?

[sololove2d]

First post, please be gentle

I Wrote a function, that I WOULD LIKE it to do the following:

When player sprite runs to certain x, y.
Player sprite will not move for 1.5 second.
During this 1.5 sec, showing a turning coin.
After this 1.5, roll a random number, if greater than N, player sprite continue to move its original direction.

Code: Select all

function resolveTrap(dt, player)
  for i, t in ipairs(traps) do
    if distanceBetween(t.x + t.width/2, t.y + t.height/2, player.body:getX(), player.body:getY()) <= 25 and player.clear == false then
      trapDiff = t.difficulty
      local directionOrigin = player.direction
      player.direction = 0
      
      gameMode = 3
      rollingTimer = rollingTimer + dt
      if rollingTimer >= 1.5 then
        skillOut = math.random(0, player.skill01)
        if skillOut > t.difficulty then
          player.direction = directionOrigin
          player.clear = true
        elseif skillOut <= t.difficulty then
          player.direction = -directionOrigin
        end

      end
      gameMode = 2


    end
  end
end

In love.draw function:

Code: Select all

 
  if h01.direction == 0 then
    rollingNumber.animation:draw(sprites.coin_sheet, 100, 600, nil, nil, nil, 20.5, 21)
  end
  

In love.update function:

Code: Select all

  
  if rollingTimer > 2 then
    rollingTimer = 0
  end
  

My issue seems to be, after the number checking, the player sprite does not continue to move. I am not sure if I am closing the loop properly at this point. If I remove rollingTimer and such, it works fine, just no sprite pause, and continue to move right away.

After some debugging. It seems that the if statement check with the random number is not executing for some reason.

Code: Select all

        if skillOut > t.difficulty then
          player.direction = directionOrigin
          player.clear = true
        elseif skillOut <= t.difficulty then
          player.direction = -directionOrigin
        end

Could not find out where is the logic stops it.

You should try to use a library like: https://github.com/vrld/hump/blob/master/timer.lua
It is made specialy to make it easy to do stuff like "after x time do that", "during x time do that" .

Code: Select all

      if rollingTimer >= 1.5 then
        skillOut = math.random(0, player.skill01)
        if skillOut > t.difficulty then
          player.direction = directionOrigin
          player.clear = true
        elseif skillOut <= t.difficulty then
          player.direction = -directionOrigin
        end
 

Here when rollingTimer is more than 1.5, the body of the if statement will be called every gameloop, so skillOut will be set every time.

Thanks lot. I will check out timer.lua.

When you say game loop, that means every dt frame?

Yes, you can see the mainloop/gameloop here :
