[Trigger] Replace Terrain Tiles

Scytharius · Mar 8, 2015

There is no such resource for this type of trigger as I have looked. It seems to be a bit advanced for a lot of people.

Here's what it needs to do:

Iterate from tile to tile, if the tile is equal to a grass tile, replace the grass tile with a snow tile. Once it reaches the end of the map, it needs to move down by point(0, -100) and start from the beginning again. By doing this, all grass tiles will be changed to a snow tile. Eventually, once all grass tiles are replaced, the trigger needs to turn off.

My map is set to 256x256.

I only use GUI. I don't mind Jass as long as you can explain it so I can alter it.

Change to Snow
- Events
  - Time - Every 0.01 seconds of game time
- Conditions
- Actions
  - Set tmp_point = (Point(((X of tmp_point) + 100.00), ((Y of tmp_point) + 0.01)))
  - If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    - If - Conditions
      - (Terrain type at tmp_point) Equal to Lordaeron Summer - Grass
    - Then - Actions
      - Environment - Change terrain type at tmp_point to Lordaeron Winter - Snow using variation -1 in an area of size 1 and shape Circle
    - Else - Actions

If you take a look yourself on a solution for this on the hive or internet, you will see that there is none. Can anyone help with it?

Well maybe instead of replacing the tiles you could just build invisibles buildings with a snowy base, or invisibles doodads with a snowy base. and just remove all the possible interactions with those buildings/doodads like colliders and selections ect..

Just an idea, I don't think you can actualy replace a texture ingame can you?
Or if you do maybe you should have the snow tiles already in your custom tiles in the map options ..
Maybe use the "corrupted soil ability" of the undeads and replace the corrupted soil by snow ..?

My game has 4 seasons that you can choose from at the beginning of the game: Spring, Summer, Fall, and Winter. Depending on the season chosen, the grass tiles will be replaced by the said tile.

It would look awful if I had to replace every single tile on the map with the snow tile. I need it to target one specific tile and replace it.

The tiles need to change in-game and not in the terrain editor.

It's too simple that's why no one is making it. If you know how it works, why don't you code it by yourself?

You can use [Snippet] TileDefinition to help the iteration accuracy. But it's vJass

It's not approved yet but I guarantee it works flawlessly, it's just because moderators are slow.

I can only explain it and code some of it, I don't know how to check whether the tile is hitting the edge of the map and if it is, -1 down and start moving the other way.

For example,

> = tile moving right

< = tile moving left

| = y-point value -100 which makes it go down once

] [ = map edges

Map
Start[>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>]drop y-value -100
drop[<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<] |
| [>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>]drop etc

I just don't know how to check whether it is hitting the edge of the map. Also, I have no idea where the terrain tile starts( it keeps starting near the bottom.. and I am not giving it any y-values.) or even the start location of the very top left of the map, to start iterating it.

Iterating through the whole 256x256 map could be really heavy, it's okay to be done at map loading, but in-game, it could causes a bad freeze moment. Are you sure about this? I can make one for you.

Scytharius · Mar 8, 2015

It would only happen at the start of the game and when the seasons change. (Each season has 30 days and each day lasts about 2-5 minutes. After the 30th day of the season, the terrain tiles will change.)

I would love the system just as long as it doesn't kill the game with lag/freezing. Some lag is fine in order to replace the tiles, but if it is a lot of lag, then it isn't worth it.

It depends, from hearing how my game works, are you able to implement it without major lag / freezing?

You could have the snow terrain replace the grass at a slower pace, all the snow terrain doesn't have to iterate through the whole thing at once (if you can accomplish something like this.)

EDIT: Oh and also, the terrain tiles won't iterate through the whole map. It will iterate through a region that covers about 1/3rd of the map. Sorry, forgot to mention.

More like Rune Factory.

I can't run the map, script error.. lol

Kazeon · Mar 8, 2015

Sorry, try this:

Scytharius · Mar 8, 2015

It worked on your test map, but I got another error when importing it into my map. ( I didn't touch a thing other than changing the region.)

Also, it seems that the snow tiles get replaced with a rock tile. All rock tiles don't get replaced.

Kazeon · Mar 8, 2015

You need to copy all variables from the demo map.

There is a variable called CT__Switch. If true, both tiles will be replacing each other, if false, will only change original tile to target tile.

Scytharius · Mar 8, 2015

I switched on "automatically create unknown variables while pasting trigger data" in file > preferences.

Nothing in the trigger is marked red.

Kazeon · Mar 8, 2015

Because I use custom scripts ._. Just do what I instructed.

Scytharius · Mar 8, 2015

I'm sorry. I don't know jass. I thought you would have added the variables in already or explained how to do that. I have a general idea how but I have never used jass / custom scripts.

I tried to make a variable that the custom script uses, but it still won't run past it.

Try to copy "VarCreate" trigger from this demo map to your map then just delete that trigger afterwards. It will automatically copy all needed variables.

Scytharius · Mar 8, 2015

Sorry again..

Still errors.

There.

Next time try to read our instructions carefully.

Not everybody always have times to help.

Dr Super Good · Mar 9, 2015

Still errors.

Did you declare the required global variables? All the names prefixed with "udg_" are GUI global variables.

I didn't know there could be code in the map header, never knew about it until now.

I got it to work, but I can't get it to work how I want it to.

I am trying to make both triggers callable, having ChangeTile and Tilevariables turned off initially and then when a season is selected at start by the players, turn on both triggers.

Month Chosen
- Events
  - Time - Elapsed game time is 22.00 seconds
- Conditions
- Actions
  - If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    - If - Conditions
      - Month_Chosen_Fall Greater than Month_Chosen_Spring
      - Month_Chosen_Fall Greater than Month_Chosen_Summer
      - Month_Chosen_Fall Greater than Month_Chosen_Winter
    - Then - Actions
      - Set CT__TargetTile = Barrens - Grassy Dirt
      - Trigger - Turn on Tilevariables <gen>
      - Trigger - Turn on ChangeTile <gen>
    - Else - Actions

It seems Tilevariables and ChangeTile work best as initialization, but I need them to be callable so I can change the tile for each season (during the game). Also, the iteration location needs to reset and I am not sure if it does that. Depending on the season chosen, the variable "CT__TargetTile" needs to hold a different tile.

Kazeon · Mar 9, 2015

So you are totally new with triggering huh? You just need to do the same exact thing on season change.

You don't need to enable/disable the ChangeTile trigger because it won't run unless you call it using:

Custom script: call ExecuteFunc("ChangeTiles")

You need to spend more time to learn the trigger more. Don't ask every single thing.

Btw, your condition checking seems weird here:

Month_Chosen_Fall Greater than Month_Chosen_Spring
Month_Chosen_Fall Greater than Month_Chosen_Summer
Month_Chosen_Fall Greater than Month_Chosen_Winter

Are you sure it's okay?

I will give you an example, on winter you want to replace grass to snow. So on season change event:

Code:

Event - Season Changed
Condition - NextSeason is Winter
Action - 
   Set CT__OriginalTile = Lordaeron Summer - Grass
   Set CT__TargetTile = Lordaeron Winter - Snow
   Set CT__TargetTileVariation = -1
   Set CT__Rect = Random Spawn Point <gen>
   Set CT__IterationDelay = 0.03
   Set CT__Switch = False
   Custom script: call ExecuteFunc("ChangeTiles")

Read carefully and try to understand.

Good luck with your map.

Scytharius · Mar 9, 2015

Ohhh.

I totally get it now.

I have never really used custom scripts. I know now how to operate the system. You are awesome Dalv. Thanks a lot for the walk through, I will remember to give credits. Amazing system.
