## Methods
|
|
```gdscript
|
|
hook.GetTable()
|
|
hook.Add(event: String, uid: String, function: FuncRef)
|
|
hook.Call(event: String, args: Array)
|
|
hook.Remove(event: String, uid: String)
|
|
```
|
|
|
|
## Usage
|
|
`hook.Add` creates a new listening event and `hook.Call` executes all listening events of the same type, for example:
|
|
|
|
```gdscript
|
|
# autorun.gd
|
|
|
|
var hook: Hook = Hook.new()
|
|
|
|
func printHookOutput1(a: String, b: String):
|
|
print(a, " ", b)
|
|
|
|
func printHookOutput2(a: String, b: String):
|
|
print(a, " ", b)
|
|
|
|
hook.Add("OnReady", "UniqueName1", funcref(self, "printHookOutput1"))
|
|
hook.Add("OnReady", "UniqueName2", funcref(self, "printHookOutput2"))
|
|
```
|
|
```gdscript
|
|
# any node script
|
|
|
|
func _ready():
|
|
hook.Call("OnReady", ["Hey!", "It's OnReady hook!"])
|
|
```
|
|
|
|
`hook.Remove` removes any listening event by its name and type:
|
|
|
|
```gdscript
|
|
# can be executed at any place
|
|
|
|
hook.Remove("OnReady", "UniqueName")
|
|
```
|
|
|
|
`hook.GetTable` returns a `Dictionary` with all added listening events
|
|
|
|
```gdscript
|
|
# can be executed at any place
|
|
|
|
var hookTable: Dictionary = hook.GetTable()
|
|
```
