Rare spawn?

[Foxace]

How to create rare monster spawn? for an example there is 1% chance that certain npc spawns in the map and the monster could spawn at any time, even multiple times during the game.

- Periodic check
- if random integer between 0 and 99 is equal to 0
- spawn the monster
- set the monster to a variable
- disable this trigger

Another trigger :
- A unit dies
- The unit is the monster stored into the variable
- Enable the first trigger

Why unit needs to be variable?

 

[Dr Super Good]

So you can check if the unit dying is equal to the rare monster. It is to stop double spawns.

Why cant I just add normal "create unit" and refer to that unit?

 

[Dr Super Good]

refer to that unit

Yeh and what do you think the unit variable is doing? It certainly is not referring to a player or a string. It refers to the rare unit you create.

Why cant I just add normal "create unit" and refer to that unit?

If you have "x = 2" then how do you refer to the number 2? Same thing.

 

[Malhorne]

It needs to be a variable otherwise how do I get the unit ?
The purpose of variables are to reference to values.

 

[Foxace]

Why cant I just add in first trigger "create unit of unit type" and then in second if there are no alive units of unit type then start the periodic event.

 

[Malhorne]

This is less good than the previous
Why are you scared of variables ?
This is MUST HAVE in nearly every trigger zzz

 

[Nichilus]

And how is the game supposed to know if there are any alive? The only thing you could do is check EVERY unit in map and check if any of them is Rare unit and is alive... and you would have to do this either periodically or whenever any unit dies - veeery inefficient and lag-prone.

I don't really understand your problem with variables and why you are trying to avoid it.
Instead of this:

Timer expires
-> Spawn Rare
-> Set unit_var = spawned rare creep



Unit dies
- dying unit = unit_var
-> start timer

you're trying to avoid variable and instead try to think of an "easier" way, which in the code is actually far longer and very inefficient.

 

[Malhorne]

Yep you can use region in his way but it is far less efficient ^^
And use a region variable xD !

Condition number of alive unit of units of unit type

This has worked for me in previous unit spawn systems without any problem.

 

[Malhorne]

It is HIGHLY inefficient and slow.
And you're asking for solution I give you and then you argue about something which is bad I don't understand >_<

 

[Foxace]

It hasnt slowed my game, so why should I make things complicated if there is simple solution?

 

[Malhorne]

What is complicated with my solution ?
And btw with your way more units on the map will lead to lower performance and when you'll have plenty of eye candy spells and this spawn occurs it will lag as hell...
But hell ya continue like this ><

 

[Nichilus]

Exactly. Afaik "Number of unit-type units in (Map)" would look like this in GUI:
*for simplicity, imagine I check number of Footman-type units*

X = 0
Pick every unit in (Playable map area) and do (actions)
    Loop
        If (conditions)
            Unit-type of (Picked unit) == Footman
        Then (actions)
            set X = X + 1
        Else (actions)
            *nothing*
... return X (X is number of Footmen in map)

To conclude this: The "number of units in *somewhere*" creates unit group and iterates through each unit in that group.
The creation of unit group is a heavy process and should be used as little as possible, since in conjuction with other heavy process it will start lagging your game.
As I wrote, it iterates through each unit in map - Now, it's fine and all when you have ~10 units in map, however it will be quite the problem when you have 100 units in map.
Add to it that you would either need to use this periodically, or whenever any unit dies.

So yeah - it's definitely possible to do it like that, but the playability of your map will drop a lot during actual game.

 

[Malhorne]

And you're leaking the group btw ^^

How to set unit in variable in trigger?

 

[Malhorne]

• Set MyUnit = (Last created unit)
