Editing Map Events

Events are what bring your maps to life. They include NPCs, signposts, warps, scripts, and more. Open the Events tab above the map area, and let’s dissect what’s going on.

Map Events View

Map Events View

All of the events are visible on the map. The Event Details window on the right displays the properties of the currently-selected event. If you look closely, you’ll see that the woman NPC near the Pokémon Center has a pink border around it because it’s selected. To select a different event, simply click on an event in the map area. Alternatively, you can use the spinner at the top of the event properties window. Multiple events can be selected at the same time by holding Ctrl and clicking another event.

Warning

There is currently no undo/redo functionality when editing events! Use Git version control!

Adding & Deleting Events

To add a new event, press the green plus button. add-event-button You can choose between the different types of events by clicking the small arrow on the right. You can also duplicate any currently selected events with Ctrl+D.

To delete the selected event, press the delete button. delete-event-button

Event Positions

All events have X/Y coordinates. To move an Event, click and drag it to a new position on the map. Alternatively, you can use the X and Y spinners in the event properties.

Event Coordinates Spinners

Events also have an elevation, also known as Z coordinates (see image above). Elevations are explained in detail in the Collision Types section.

Next, we’ll cover each type of event in detail.

Object Events

Object events are typically used for NPCs (non-player-characters). More technically, it’s any event that has a sprite and the ability to move around. Object events are displayed using their assigned sprite, except for special cases. Any object event that uses a dynamic sprite will be displayed as a blue square with an N dynamic-sprite. Some examples of dynamic sprites are the player’s rival and berry trees.

Object Event Properties

Object Event Properties

Id
This is the local id of the object in the map. Some script values use this local id to specify an object when using scripting commands such as applymovement.
Sprite
The sprite that is used by the object.
Movement
The movement type used by the object during normal gameplay.
Movement Radius X/Y
Movement types that involves walking or moving around the map can be bounded by a radius. The ensures that the object is always within the specified range from its original position.
Script
The script that executes when the player interacts with the object.
Event Flag
The flag value that controls if the object is visible. If the flag is set (equal to 1), then the object will be invisible. If the Event Flag is set to 0, then the object will always be visible because 0 means “no flag”.
Trainer Type
The trainer type used by the object. If the object is a trainer, TRAINER_TYPE_NORMAL means that the trainer will spot the player in the object’s line-of-sight.
Sight Radius or Berry Tree ID
If the object is a trainer, this property control how many tiles the trainer can see to spot the player for battle. If the object is a berry tree, this specifies the global id of the berry tree. Each berry tree in the game has a unique berry tree id.

Clone Object Events

Clone Object events are a special type of object that inherits its properties from another Object event. They are used in-game to load objects that are visible in the connecting area of adjacent maps. The targeted object to clone is specified by id and map name. If the targeted object does not exist, or it’s also a clone, the sprite for graphics id 0 will be displayed instead. Double-clicking on a Clone Object will open the targeted map with the targeted object selected. This event type is exclusive to pokefirered projects; the code to process them does not exist in pokeemerald/pokeruby.

Clone Object Event Properties

Id
This is the local id of the object in the map. Some script values use this local id to specify an object when using scripting commands such as applymovement.
Sprite
The sprite that is used by the object. Clone Objects inherit their sprite from the targeted object, so this cannot be edited. This field is not actually read by the game.
Target Local Id
The local id of the object to be cloned.
Target Map
The name of the map the object to be cloned is on.

Warp Events

Warp events are how the player is able to warp to other maps, such as entering a building. Double-clicking on a warp will automatically open the destination map and select the destination warp. This makes it very easy to navigate around in Porymap. Warps need to be on specific metatiles to function as an exit; a warning will appear if the warp event is not on one of these metatiles.

Warp Event Properties

Warp Event Properties

Id
This is the local id of the warp in the map. This is used when setting the Destination Warp property for another warp.
Destination Map
The destination map name.
Destination Warp
The Id of the warp in the destination map.

Trigger Events

Trigger events are scripts that execute when the player walks over them. However, they only execute when a variable is equal some value. Typically, they execute once, set the variable’s value to something else, and then never execute again because the variable’s value no longer matches.

Trigger Event Properties

Trigger Event Properties

Id
The local id of the trigger in the map. This value is not used for anything.
Script
The script that executes when the player walks over the trigger AND when the Var equals the Var Value.
Var
The variable used to determine if the trigger’s Script should execute.
Var Value
The value that the Var must equal for the trigger’s Script to execute.

Weather Trigger Events

Weather trigger events are a very specific type of trigger. When the player walks over a weather trigger, the overworld’s weather will transition to the specified weather type. This event type is unavailable for pokefirered projects; the functions to trigger weather changes were dummied out.

Weather Trigger Event Properties

Weather Trigger Event Properties

Id
The local id of the trigger in the map. This value is not used for anything.
Weather
The type of weather to transition to.

Sign Event

Sign events, or signposts, are simple interactable scripts. They are typically used for things like signs in front of buildings. The player’s facing direction can be required to be a certain direction in order to interact with the sign. Signs are the first of three “BG” event types.

Player Facing Direction
The direction the player must be facing in order to execute the sign’s script.
Script
The script that executes when the player interacts with the sign.

Hidden Item Event

Hidden items are invisible items that can be picked up by the player. They each use a flag to ensure the item can only be picked up once.

Hidden Item Event Properties

Id
The local id of the BG event in the map. This value is not used for anything.
Item

Quantity
Exclusive to pokefirered. The number of items received when the item is picked up.
Requires Itemfinder
Exclusive to pokefirered. When checked, the hidden item can only be received by standing on it and using the Itemfinder.

Secret Base Event

This is the event used to mark entrances to secret bases. This event will only be functional on certain metatiles. Unfortunately, they are hardcoded into the game’s engine (see sSecretBaseEntranceMetatiles in src/secret_base.c). This event type is unavailable for pokefirered projects; secret bases do not exist there.

Secret Base Event Properties

The local id of the BG event in the map. This value is not used for anything.
Secret Base Id
The id of the destination secret base.

Heal Location / Healspots

This event is used to control where a player will arrive when they white out or fly to the map. The white out functions a little differently between game versions. For pokeemerald and pokeruby players will arrive at the event’s coordinates after a white out, while in pokefirered they will arrive on the map set in Respawn Map and at hardcoded coordinates (see SetWhiteoutRespawnWarpAndHealerNpc in src/heal_location.c).

Heal Location Properties

Heal Location Properties

Respawn Map
Exclusive to pokefirered. The map where the player will arrive when they white out (e.g. inside the PokéCenter that the heal location is in front of).
Respawn NPC
Exclusive to pokefirered. The local id of the NPC the player will interact with when they white out.

Open Map Scripts

Clicking the Open Map Scripts button open-map-scripts-button will open the map’s scripts file in your default text editor. If nothing happens when this button is clicked, you may need to associate a text editor with the .inc file extension (or .pory if you’re using Porycript).

Additionally, if you specify a Goto Line Command in Options -> Edit Preferences then a tool-button will appear next to the Script combo-box in the Events tab. Clicking this button will open the file that contains the script directly to the line number of that script. If the script cannot be found in the project then the current map’s scripts file is opened. go-to-script-button

Tool Buttons

The event editing tab also extends functionality to a few of the tool buttons described in Editing Map Tiles. A brief description and animation is listed for each of the available tools below:

Pencil
When clicking on an existing event, the pencil tool will behave normally (as the standard cursor). It can also be used to “draw” events in a certain location. The event created will be a default-valued event of the same type as the currently selected event. Right-clicking with the Pencil Tool will return to the Pointer tool.

Pointer
The Pointer Tool is the default tool for the event editing tab and allows you to select and move events on the map. The Pointer Tool also gives you access to the Ruler Tool.
Shift
You can use the Shift Tool to move any number of events together. When a selected event is dragged, all other selected events will move with it. When a tile with no event is clicked, all events on the map can be dragged.

Ruler Tool

The Ruler Tool provides a convenient way to measure distance on the map. This is particularly useful for scripting object movement. With the Pointer Tool selected you can activate the ruler with a Right-click. With the ruler active you can move the mouse around to extend the ruler. The ruler can be deactivated with another Right-click, or locked in place with a Left-click (Left-click again to unlock the ruler).
