The GetDistance function returns a numerical value which indicates how far away a reference is from a specified point.

We will use the distance 300 which is fairly close to but not necessarily on top of the x marker we made. When the character gets close we want to move to stage 40. We can use the stage to limit when the active part of the script runs. We first need to add stage 40 in the stage tab. | We will use the distance 300 which is fairly close to but not necessarily on top of the x marker we made.

We also want to know when each item is picked up so we can display a suitable message informing the player to keep looking. Again this is hand holding, and can be left out for a greater challenge and a deeper immersion. | We also want to know when each item is picked up so we can display a suitable message informing the player to keep looking.

So we declare the three variables to add to our variable list at the top of the script. You will notice that the list keeps growing as we find we need new variables. | So we declare the three variables to add to our variable list at the top of the quest script (''BGM001QuestScript'').
