Not sure if this is the best method, but you could try something like in the Hogwarts Battle mod. https://steamcommunity.com/sharedfiles/filedetails/?id=2867610721&searchtext=hogwarts

--This is used by another function to locate information on what is in an area
function findObjectsAtPosition(localPos)
    --We convert that local position to a global table position
    local globalPos = localPos
    --We then do a raycast of a sphere on that position to find objects there
    --It returns a list of hits which includes references to what it hit
    local objList = Physics.cast({
        origin=globalPos, --Where the cast takes place
        direction={0,1,0}, --Which direction it moves (up is shown)
        type=2, --Type. 2 is "sphere"
        size={2,2,2}, --How large that sphere is
        max_distance=1, --How far it moves. Just a little bit
        debug=false --If it displays the sphere when casting.
    })

    --Now we have objList which contains any and all objects in that area.
    --But we only want decks and cards. So we will create a new list
    local decksAndCards = {}
    --Then go through objList adding any decks/cards to our new list
    for _, obj in ipairs(objList) do
        if obj.hit_object.tag == "Deck" or obj.hit_object.tag == "Card" then
            table.insert(decksAndCards, obj.hit_object)
        end
    end

    --Now we return this to where it was called with the information
    return decksAndCards
end

The way its used here is to detect objects in a specific area. Which happens to be next to a little token. I would imagine you could pass along the location of tile.

Might need to change the Physics area to something like this

local objList = Physics.cast({
        origin=globalPos, --Where the cast takes place
        direction={0,1,0}, --Which direction it moves (up is shown)
        type=3, --Type. 2 is "sphere"
        size={2,2,2}, --How large that sphere is
        max_distance=1, --How far it moves. Just a little bit
        debug=true --If it displays the sphere when casting.
    })

#

And then also change the size depending on what you need

if you take the tile by hand and move it, that works. Thanks but this method is too complicated for me, i'm trying to understand but it's above my hat.

I once made a rotating board which grabbed the pieces on it (somebody else helped me with that), I'm trying to work on that code to get it to work. Right now, it works for rotation, so it might work for movement also. Still, a bit heard to understand what every code does.

local rotate_button = {
  click_function = "rotateBoard",
  function_owner = self,
  label = "move",
  position = {0, 1, 0},
  scale = {0.1, 0.1, 0.1},
  width = 750,
  height = 750,
  font_size = 200
}

local resting_objects = {}

function onLoad(save_state)
  -- Add the button.
  self.createButton(rotate_button)
end

function onCollisionEnter(collision_info)
  -- Grab the colliding object.
  local col = collision_info.collision_object
  -- If the object isn't supposed to rotate (a specific object and the table)...
  if col.getGUID() ~= "3a27ae" and col.tag ~= "Surface" then
    -- Add it to the list of objects resting on top of the target.
    resting_objects[col.getGUID()] = true
  end
end

function onObjectPickUp(player_color, picked_up_object)
  -- If the object is an object resting on top of the target...
  for guid, on_field in pairs(resting_objects) do
    if guid == picked_up_object.getGUID() then
      -- Remove it from the list of objects resting on top of the target, as it has been picked up.
      resting_objects[guid] = false
      return
    end
  end
end

function rotateBoard()
  -- If the board is currently moving, do not rotate the board.
  if not self.resting then
    return
  end

  -- For each of the resting objects...
  for i, v in pairs(resting_objects) do
    if v then
      -- Attach the object to the board.
      local obj = getObjectFromGUID(i)
      self.addAttachment(obj)
    end
  end
  -- Rotate the board.
  local rotation = self.getRotation()
  rotation.y = rotation.y + 45
  self.setRotation(rotation)
  -- Detach the objects.
  self.removeAttachments()
end

use a Physics.cast() to find the objects above, store their position local to the tile using .positionToLocal(), and their relative rotation by recording the difference between their .getRotation() tables.
move your tile
rotate and move the objects from before, using .positionToWorld() and applying the rotation differences to the tiles new rotation (assuming it also rotated)

Where would you put code like this? OnObjectPickup? Player.Action.Pickup?

next sandal Jul 26, 2023, 8:14 AM

#

periodically, or onLoad(), as onObjectPickUp() is called one frame after picking up, it'd be too late if you used it

sturdy matrix Jul 26, 2023, 10:43 AM

it's still very difficult for me. A template-script would be nice.

It didnt' seem to work, I'm sure I made mistakes in codes I don't fully understand 😦

object1_GUID = '2786c0'

    TILE = getObjectFromGUID(object1_GUID)
    TILE.createButton({
        label="move1", click_function="move1",

        height=100, width=400, font_size=100
    })
end

-- -------------------------------------------------------------------------
function move1()
    local positionToMove = {x = 0, y = 1, z = 0} 

    local colliders = Physics.cast({origin=TILE.getPosition(), direction={0,1,0}, type=3, size={TILE.getBounds().size.x, 100, TILE.getBounds().size.z}, max_distance=0, debug=false})
    for _, collider in ipairs(colliders) do
        if collider.hit_object != TILE then
            local posInTILELocal = TILE.positionToLocal(collider.hit_position)
            local newPos = positionToMove
            newPos.y = newPos.y + posInTILELocal.y
            collider.hit_object.setPositionSmooth(TILE.positionToWorld(newPos), false, true)
        end
    end

Is his new? Normally when I boot the game the buttons appeared immediately, but now they don't appear until I press this box "play script's in the bottom right.

turn "auto-run" on in the scripting window (in TTS)

you've also skipped step 2 in my 3 step plan

next sandal you've also skipped step 2 in my 3 step plan

because i don't need rotation i thought i could skip it. I'll try again.

sturdy matrix Jul 28, 2023, 8:25 PM

I don't think it can be done.
Everytime i try i get an error but never succeed, for something as simple (picking up by hand works fine)

I understand.
OK this is my script that works perfectly (except that it doesn't take the cards with it) : just two tiles, moving from one location (l1) to another (l2) and back.
object1 is just an item with the buttons

object1_GUID = 'f013da'
object2_GUID = '0d9219'
object3_GUID = '2786c0'

l1 = {-20, 20, 0}
l2 =  {20, 10, 0}
l3 = {-20, 20, -10}
l4 = {20, 10, -10}
-- -------------------------------------------------------------------------
function onLoad()
rood = getObjectFromGUID(object1_GUID)
TILE2 = getObjectFromGUID(object2_GUID)
TILE1 = getObjectFromGUID(object3_GUID)

rood.createButton({
   label="move1", click_function="move1",
   function_owner=self, position={0,0.4,1},
   height=100, width=400, font_size=100
})
rood.createButton({
   label="back1", click_function="back1",
   function_owner=self, position={0,0.4,1.5},
   height=100, width=400, font_size=100
})
rood.createButton({
   label="move2", click_function="move2",
   function_owner=self, position={0,0.4,2},
   height=100, width=400, font_size=100
})
rood.createButton({
   label="back2", click_function="back2",
   function_owner=self, position={0,0.4,2.5},
   height=100, width=400, font_size=100
})
end
-- -------------------------------------------------------------------------
function move1(entity, color)
TILE1.setPositionSmooth(l1)
end

function back1(entity, color)
TILE1.setPositionSmooth(l2)
end
-- -------------------------------------------------------------------------
function move2(entity, color)
TILE2.setPositionSmooth(l3)
end

function back2(entity, color)
TILE2.setPositionSmooth(l4)
end

well, it won't take the cards with it because you've now omitted steps 1 and 3 of my 3 step plan

sturdy matrix Jul 29, 2023, 6:05 AM

#

yes I know 🙂 I'm going to add that bit by bit (my first attempt was so wrong I have to redo it completely).

step 1 : use a Physics.cast() to find the objects above, store their position local to the tile using .positionToLocal(), and their relative rotation by recording the difference between their .getRotation() tables.

step 3 : rotate and move the objects from before, using .positionToWorld() and applying the rotation differences to the tiles new rotation (assuming it also rotated)

Give me a little time to figure out how to script that (I wish there was a good tutorial somewhere online)

sturdy matrix Jul 29, 2023, 10:11 AM

not working though 😦

#

well, you're defining MoveObjectsAboveTile1 inside another function, which probably isn't intentional.

#

using .setPositionSmooth() will be a problem if you are immediately changing the position of the decks, as the tile won't yet have moved

#

(I wish there was a good tutorial somewhere online)
You'll never find a tutorial for how to combine different scripts together. The only thing that can give you this knowledge is experience and practice.

#

how they combine is a fundamental part of what they do, and there would therefore be more combinations than seconds you have lived

sturdy matrix Jul 29, 2023, 2:46 PM

i do understand that 🙂 however that doesn't make it easy. Thanks for the help, much appreciated 🙂

sturdy matrix Aug 3, 2023, 5:04 AM

#

it took a while, but now i'm getting somewhere. In fact i made this "game" with 4 taxi's who can move forward and backwards and also move the items that are on top of them. The scripts are on the custom tokens, I would like the buttons to be separated from them, on a fixed place on the board, but i'm already very happy with the result.
