| − | Events are a package of information that can be passed around in the game to trigger some behaviour. They are usually passed off to an [[object]]'s [[event script]] for handling, but there are a few engine-only event types that are not exposed to the end-users.

| − | Scripting Events have an integer type, target object, a time delay and a package of parameters (arbitrary number of [[int]]s, [[object]]s, [[float]]s and [[string]]s). Certain event types will be defined by the engine and referenced as #defines in the scripts.
| + | == Description == |
| | + | <!-- This section contains the full description from the functions comments. Do not change unless you are confident these are incomplete or incorrect. --> |
| | + | Creates an event of the specified type. |
| | | | |
| − | Events are handled in the scripting language with the following types of commands:
| + | <!-- == Remarks == --> |
| − | * Event() Constructor — Scripters can create events of any type and signal them to other objects
| + | <!-- This section contains additional comments, observations and known issues. --> |
| − | * Signal Event commands — Events can be signalled to a single object, by proximity or to all objects with a certain group id
| + | |
| − | * Parameter access — All of the parameters on an event can be get and set through scripting.
| + | |
| − | * Event handling — Events can be passed to other script files through the HandleEvent command. This command will be run inline so that hierarchies of event-handling behaviour can be built.
| + | |
| | | | |
| − | A typical event-handling script would have the form
| + | <!-- == Examples == --> |
| | + | <!-- This section contains examples transcluded from the snippet library. --> |
| | | | |
| − | <dascript> | + | <!-- == See also == --> |
| − | void main()
| + | <!-- This section contains links to articles, functions or constant groups. --> |

| − | In the event that you want to intercept some events but leave others to be handled by a default script (for example if you're overriding one aspect of a creature's event response but the rest of the default creature_core responses responses are fine) you can pass execution to the default script with the following:

| + | |
| − | HandleEvent(ev, RESOURCE_SCRIPT_CREATURE_CORE);
