This is an easy-to-implement spawn system which allows a great deal of customization in wave spawns by using hashtables as a double array indexing system to determine unit types and level of difficulty. It is entirely GUI and no Jass knowledge is required to create triggers with the system.
The system spawns unit waves which numbers and variation of unit types can be customized entirely to fit progression. For instance, the 1st wave might spawn 3 Footmen and 1 Priest, while the 27th wave could spawn 7 knights, 3 Sorceress and 2 Mortar Teams.
- Unit Types
The system saves different types of unit to a hashtable in the map initialization, which are then later used for spawning units in a systematic order.
- Difficulty
The system uses levels of difficulties to slowly and automatically increase the strength of units.

Copy all triggers from Map Initialization and Map Triggers into your map. Make sure that your preferences are set to automatically generate unknown variables while pasting trigger data.
- Editing Variables
You have to update the following variables:
“SpawnPoint” and “SpawnAttack”: Change these variables to match the points in your map.
"Player 2": In the Spawn trigger, change Player 2 to whichever computer player that is controlling the spawn units.
- Adding Spawns
To add spawns to your map, you need to save them to the Hashtable trigger with the following actions:
Modify the unit type to the unit type you wish to add.
You need to change “as 0” to an index that’s not already in use, and avoid spaces between indexes. For instance, if you save 3 different unit types, save them as 0, 1, and 2.
“of 0” is the level of difficulty at which the unit types are created.
Example:
- Setting Spawn Numbers:
To modify the number of units created, adjust the variables in the triggers “Variables” and in any difficulty level triggers.
The variable SpawnNumber[Index] controls how many units are created of each index (“as 0”) in the current level of difficulty. You need to set the specifics for this variable to vary the amount of units created.
Example:
- Setting Spawn Waves:
The variable “SpawnWaves” is how many waves there are left before the difficulty increases.
“SpawnIncrement[Index]” controls how many waves there are at each level of difficulty.
Example:
To vary the number of units and unit-types created at each level of difficulty, simply create a trigger to update the variables:
The events picks up on when the difficulty is increased.
- SpawnTypes determine how many different types that are created in the wave, from the unit-types you set in the hashtable at the current level of difficulty.
- Update SpawnNumber to the numbers of each type you wish to be spawned.
The “Begin Game” and “Wave End” triggers are just examples of the frequency at which you can create waves. You might want to create a periodic time event trigger to run the spawn trigger every X seconds. This completely depends on how you want your spawn system to be.

How To Implement

Copy all triggers from Map Initialization and Map Triggers into your map. Make sure that your preferences are set to automatically generate unknown variables while pasting trigger data.
- Editing Variables
You have to update the following variables:
“SpawnPoint” and “SpawnAttack”: Change these variables to match the points in your map.
"Player 2": In the Spawn trigger, change Player 2 to whichever computer player that is controlling the spawn units.
- Adding Spawns
To add spawns to your map, you need to save them to the Hashtable trigger with the following actions:
Trigger:
- Actions
- Set Temp_Type = Your Unit Type
- Custom script: set udg_Temp_Integer = udg_Temp_Type
- Hashtable - Save Temp_Integer as 0 of 0 in (Last created hashtable)
Modify the unit type to the unit type you wish to add.
You need to change “as 0” to an index that’s not already in use, and avoid spaces between indexes. For instance, if you save 3 different unit types, save them as 0, 1, and 2.
“of 0” is the level of difficulty at which the unit types are created.
Example:
To create a Footman as the first unit type spawned at difficulty 0:
And a Knight at difficulty 1:
Trigger:
- Actions
- Set Temp_Type = Footman
- Custom script: set udg_Temp_Integer = udg_Temp_Type
- Hashtable - Save Temp_Integer as 0 of 0 in (Last created hashtable)
And a Knight at difficulty 1:
Trigger:
- Actions
- Set Temp_Type = Knight
- Custom script: set udg_Temp_Integer = udg_Temp_Type
- Hashtable - Save Temp_Integer as 0 of 1 in (Last created hashtable)
- Setting Spawn Numbers:
To modify the number of units created, adjust the variables in the triggers “Variables” and in any difficulty level triggers.
The variable SpawnNumber[Index] controls how many units are created of each index (“as 0”) in the current level of difficulty. You need to set the specifics for this variable to vary the amount of units created.
Example:
A Footman is saved as index 0, a Rifleman as index 1 and a Priest as index 2:
The wave would then spawn 4 Footmen, 2 Riflemen and 1 Priest.
Trigger:
- Actions
- Set SpawnNumber[0] = 4
- Set SpawnNumber[1] = 2
- Set SpawnNumber[2] = 1
The wave would then spawn 4 Footmen, 2 Riflemen and 1 Priest.
- Setting Spawn Waves:
The variable “SpawnWaves” is how many waves there are left before the difficulty increases.
“SpawnIncrement[Index]” controls how many waves there are at each level of difficulty.
Example:
To create 10 waves at difficulty 1 and 14 waves at difficulty 2, simply set the variable to the following values in the Variables trigger:
Trigger:
- Actions
- Set SpawnIncrement[1] = 10.00
- Set SpawnIncrement[2] = 14.00
Modifying Difficulty Levels
To vary the number of units and unit-types created at each level of difficulty, simply create a trigger to update the variables:
Trigger:
- Difficulty 1
- Events
- Game - Difficulty becomes Equal to 1.00
- Conditions
- Actions
- Set SpawnTypes = 3
- Set SpawnNumber[0] = 3
- Set SpawnNumber[1] = 2
- Set SpawnNumber[2] = 1
- Set SpawnNumber[3] = 1
- Events
The events picks up on when the difficulty is increased.
- SpawnTypes determine how many different types that are created in the wave, from the unit-types you set in the hashtable at the current level of difficulty.
- Update SpawnNumber to the numbers of each type you wish to be spawned.
Create Your Own Wave Spawn Trigger
The “Begin Game” and “Wave End” triggers are just examples of the frequency at which you can create waves. You might want to create a periodic time event trigger to run the spawn trigger every X seconds. This completely depends on how you want your spawn system to be.
Example:
Trigger:
- Spawn Waves
- Events
- Time - Every 15.00 seconds of game time
- Conditions
- Actions
- Trigger - Run Spawn <gen> (ignoring conditions)
- Events
