在 unity2d 中尝试在屏幕上添加游戏时不断出现错误

Question

i'm trying to make a 2d platformer in unity and am trying to make it so that when the player falls off the cliff it shows the game over screen, however I keep getting the error code:

"Assets\Script\ShowDeath.cs(13,22): error CS1061: 'Transform' does not contain a definition for 'postion' and no accessible extension method 'postion' accepting a first argument of type 'Transform' could be found (are you missing a using directive or an assembly reference?)"

heres the code

float deathArea = -4f;
public GameObject deathUI;

void Update()
{
      if(transform.postion.y <= deathArea)
      {
            deathUI.SetActive(true);
      }
}

pretty simple code, I just can't figure out what the error means

Answer 1

turns out I spelt "position" wrong and wrote "postion" so unity didn't know what I was trying to say
