Line 1: Line 1:
There are various cases where a mapper may want to spawn units when specific actions happen. Commonly you will see spawned units in "Defense" maps, "Nexus Wars" maps, "DotA" maps, or anything else where units need to be automatically created at point or region. This page lists some of the more common situations.

== Spawn with the Data Editor ==
 
There are various ways one can make units spawn using the [[Data Editor]].
 
 
 
===Spawn Unit Ability===
 
{{Stub|section}}
 
 
 
===Spawn Unit Upon Death===
 
This can be done by creating a new [[Buff]] [[Behavior]]. In the '''Modifications +''' field, click the "Combat" tab and find the Death Response section. Now set the '''Effect''' field to a [[Create Unit]] effect.
 
 
 
==Spawn with Triggers==
 
The idea is pretty simple: place Points where you want your units to spawn and then use random integers to randomize the spawn.
 
 
 
===Trigger Reference===
 
Spawn system
 
  Events
 
  Timer - Every 15.0 seconds of Game Time
 
        ------- This is the interval of time at which the units will be spawned.
 
    Local Variables
 
        Unit Type = 0 <Integer>
 
        Random Point = 0 <Integer>
 
        Selected Point = No Point <Point>
 
    Conditions
 
    Actions
 
        Variable - Set Random Point = (Random integer between 1 and 5)
 
        General - If (Conditions) then do multiple (Actions)
 
            If Then Else
 
                General - Else if (Conditions) then do (Actions)
 
                    Else If
 
                        Random Point == 1
 
                    Then
 
                        Variable - Set Selected Point = Point 001
 
                General - Else if (Conditions) then do (Actions)
 
                    Else If
 
                        Random Point == 2
 
                    Then
 
                        Variable - Set Selected Point = Point 002
 
                General - Else if (Conditions) then do (Actions)
 
                    Else If
 
                        Random Point == 3
 
                    Then
 
                        Variable - Set Selected Point = Point 003
 
                General - Else if (Conditions) then do (Actions)
 
                    Else If
 
                        Random Point == 4
 
                    Then
 
                        Variable - Set Selected Point = Point 004
 
                General - Else if (Conditions) then do (Actions)
 
                    Else If
 
                        Random Point == 5
 
                    Then
 
                        Variable - Set Selected Point = Point 005
 
        Variable - Set Unit Type = (Random integer between 1 and 6)
 
        ------- The use of If-Then-Else is just to show that both methods work.
 
        General - If (Conditions) then do (Actions) else do (Actions)
 
            If
 
                Unit Type == 1
 
            Then
 
                Unit - Create 1 Zealot for player 0 at Selected Point using point facing (Ignore Placement)
 
                ------- Notice the point at which the unit is created is the "Selected Point" Point variable.
 
            Else
 
                General - If (Conditions) then do (Actions) else do (Actions)
 
                    If
 
                        Unit Type == 2
 
                    Then
 
                        Unit - Create 1 Sentry for player 0 at Selected Point using point facing (Ignore Placement)
 
                    Else
 
                        General - If (Conditions) then do (Actions) else do (Actions)
 
                            If
 
                                Unit Type == 3
 
                            Then
 
                                Unit - Create 1 Baneling for player 0 at Selected Point using point facing (Ignore Placement)
 
                            Else
 
                                General - If (Conditions) then do (Actions) else do (Actions)
 
                                    If
 
                                        Unit Type == 4
 
                                    Then
 
                                        Unit - Create 1 Roach for player 0 at Selected Point using point facing (Ignore Placement)
 
                                    Else
 
                                        ------- Notice I am not using the integers 5 and 6. This is simply because I wanted those two integers to represent a "No spawn" situation. More empty integers you'll have like this, less chances the spawn system will actually spawn a unit. This is just a personnal choice.
 
 
 
Please take note that there are comments within the trigger above.
