[REQUEST]World Map-Change Enemy Encounters Script

[pyrodudexiii]

Summary
A script for World Maps that will enable you to change which enemy troops you encounter depending on which region you are currently in. Ex.While on the snowy part of the world map, you would encounter Arctic Wolves and Polar Bears but when you are in the grassland area you would encounter Goblins and Trolls.

Features Desired
The ability to switch between at least 20 different Troop Variations.

Games its been in

•It's in alot of RPGs with World Maps.

Bump.

I think there is a tutorial / event system for this, look for RMXP  enemy encounters based on level or RMXP enemy encounters based on location

Thanks, I'll try to find it.

You can change each tile's terrain tag in the tileset section in the database.  This allows you to have about 7 different mob lists based on the tile you're standing on with another script.  I'm not sure if there is a way to go above the 7 maximum for terrain tag number.

Insert the following script into your game.  It's not mine, don't credit me for it.

Next, go to your world map tileset in the database and set each ground tile type's terrain tag to a different number depending on the environment it represents.  Make sure that tiles that aren't on the ground have a terrain tag of 0.

Now, make a common event, parallel trigger
The first command should set a variable to the character's terrain tag.
Now, make a conditional branch for each terrain tag.  Put this script into the conditional branch matching the correct terrain tag #

Code Select Expand

$game_map.encounter_list = [...]
Change the "..." to all of the troop ID's that you want to attack the player on that tile.  Separate them with a comma and space like this: [1, 2, 3, 4]

Now you should encounter different monsters depending on what type of tile you are standing on.

Thanks Tenraah, I really appreciate that.
