[Ace] How to modify map tiles using script call

じ☆ve冰风

Example case:



Q: Alright, but can you just do that by using tile event and flip the switch or just change the graphics and it solves the same problem?
A: You can, but then you add more events. More event means extra process and may cause lag, and also makes your game looks messy in the back end.

General thing you need to know.
We are going to make a change in tile B to E on your map. So you need to know that each tile has its own ID.
Started from tile B, from the left-top, the ID is 0, to the bottom-right, the ID is 255.
Then goes to tile C, it started from 256 to 511.
Then tile D, it started from 512, etc, you get the idea.

What are these IDs tell us? And how are we going to use it?
You can access the ID by using this script call.
                Code:        

1. $game_map.data[x, y, 2]

复制代码

X and Y are the coordinate positions of the map.
The number 2 means it's layer 2, where the tile B to E is placed.

Another Example Case:
We are going to add objects surrounding the player. I'm going to use default world map tileset as an example.
Here is what we are going to do.



And so this is what I did.



The coordinate adjacent to the player will be changed.

However, do note that the change will not be saved. So if you leave the map and re-enter, all the changes made by the script will be gone. You will need an extra effort to make the change is saved. But I think it's better for someone to make a script for that.

I guess that's all for now!


Author Notes

• I'm honestly not sure how useful it will be. But I think better tell everyone how to do the trick then it's up to their judgment how to use it.
  
• For fun, you can actually place tile B in the first layer by doing $game_map.data[x,y,0] = 1 but doing so will eliminate ground tile.
  
• If you have no idea what number a certain tile has, you can place that specific tile somewhere, and run a script call "p $game_map.data[x,y,2]" and open console log (Of course you have to change the [x,y] into the real number of the map position). It will print the number of that specific tile.
  
• You can actually make a change of the auto-tiles/Tile-A, but the number is more complicated.
