Objects
An object is a single 16x16 tile that holds its own special properties to add functionality to the game. The most common objects are simple, such as walls, ledges, or signs, but some objects can be more complex, such as doors, wraps, or stairs.
A lot of objects are pre-built within the Mapbuilder already, making your job as a developer even easier! However, you may want to be familiar with creating your own objects in case you need to.
Code Types
All objects may contain jCoad to specify their behavior. However, there are two ways that code can be added to an object.
Root code is global code that is shared across all instances of that object placed on any map. Root code is great for code that must be repeated across multiple ties, such as walls or shorelines. Instead of writing the code in every object you place, you can write it just once and place that object everywhere you need that functionality.
Instance code, or just “code,” is exclusive code to the single tile the object resides on. This code is written on a single object instance on a single map. Instance code is best for creating a unique event, such as NPC dialogue, that never needs to be repeated.
Objects can have both root code and instance code. Think of a sign. All signs are solid, but most signs hold a unique message. Therefore, a sign object would probably have the following jCoad:
solid()
msg(I am a unique sign. Only I hold this message!)
All the jCoad in this guide can be used in both root code and instance code.
