help: recreating digging + special shovel action

[THOM]

I am trying to create a special shovel. If you dig with it on a certain tile a special function should be triggered. Therefore the tile in my case is not a floortile but an invisible platform, I cannot dig in the predefined way.

I have to recreate digging.

What should happen is: digging, fade-out, a black screen for a very short time, fade in - having a dighole if there was nothing or my specials. Everything like normal digging...

But it won't work If I am clicking on my shovel nothing happens.
Has someone an idea?

I have placed 2 timers on my map that triggers after 0.5sec the events for "found nothing" and "found it". I am trying to start one of this timers by the following code, attached to the shovel-definition:

Code: Select all

onAttack = function (champion, self)

          -- define locals
          local dx,dy = 0,0
           
          -- get position modificators, to find cell in front of the party
          if party.facing == 0 then dy = -1
          elseif party.facing == 1 then dx = 1
          elseif party.facing == 2 then dy = 1
          elseif party.facing == 3 then dx = -1
          end

          -- check what is in front of the party      
          local checkedCell = entitiesAt(party.level, party.x + dx, party.y + dy)
          -- interate through all objects on cell
          for object in checkedCell do
             if object.id == "invisible_platform_diggout" then 				
			playSound("party_dig") 
			hudPrint("Digging...")
			GameMode.fadeOut(0x0,1.5)
			timer_digOut.timer:enable()		
               else
	 		playSound("party_dig") 
			hudPrint("Digging...")
			GameMode.fadeOut(0x0,1.5)     
			timer_foundNothing.timer:enable()
			spawn("dig_hole", party.level, party.x + dx, party.y + dy, 0, party.elevation)
	
             end             
	  end

  
   	end,

did you try with onUseItem = function(self) ?

[THOM]

yes - same result. nothing happened...

What I did was to combine the shovel with the horn.

Code: Select all

defineObject{
	name = "sx_shovel",
	baseObject = "base_item",
	components = {
		{
			class = "Model",
			model = "assets/models/items/shovel.fbx",	
		},
		{
			class = "Item",
			uiName = "The Spade of Ace",
			description = "This simple but reliable tool is favored by masons, farmers and treasure hunters alike.",
			gfxIndex = 404,	
			impactSound = "impact_blade",
			weight = 3,
			primaryAction = "dig",
			traits = { "usable" },
		},
		{
			class = "DiggingTool",
			name = "dig",
			uiName = "Dig",
			cooldown = 4.5,
			onUseItem = function(self)
				for e in party.map:entitiesAt(party.x, party.y) do
					if e.script and e.script.specialDigPlace then
						e.script:specialDigPlace()
					end
				end

			end,
		
		},
	},
}

So when I had the Spade of Ace shovel and I was digging where there was a script entity with the function specialDigPlace() then I could trigger whatever I wanted.

best regards.

Thanks Skuggasveinn. You brought me on my way.

Sadly I still can't get it to work.

I managed to get the shovel to trigger a script. By adding print-orders I could backtrack that the script itself is triggered.
But something seems to be wrong with the line for e in party.map:entitiesAt(party.level, party.x + dx, party.y + dy) do
after that nothing is executed...

That's written in my script:

Code: Select all

function diggingTHOM()
		--  print("test")
		
          -- define locals
          local dx,dy = 0,0
           
          -- get position modificators, to find cell in front of the party
          if party.facing == 0 then dy = -1
          elseif party.facing == 1 then dx = 1
          elseif party.facing == 2 then dy = 1
          elseif party.facing == 3 then dx = -1
          end

          -- check what is in front of the party      
    
          for e in party.map:entitiesAt(party.level, party.x + dx, party.y + dy) do

			--print("check Cell")
             if e.id == "invisible_platform_diggout" then 				
			playSound("party_dig") 
			hudPrint("Digging...")
			GameMode.fadeOut(0x0,1.5)
			timer_digExtra.timer:enable()		
               else
	 		playSound("party_dig") 
			hudPrint("Digging...")
			GameMode.fadeOut(0x0,1.5)     
			timer_foundNothing.timer:enable()
			
	
             end             
	  end


end

Ahem - anyone who can help me?

[THOM]

I am still trying to figure this out.
I could improve my script, but it's still away from finished.

The problem now is: My script runs all commands for every entity found on the target-cell. I want it running just once. If there is no object or item on the cell it doesn't run at all.

I am totaly lost with this because I am not very skilled in scripting. Anyone who has a hint for me?

Code: Select all

function diggingTHOM(self)
	--print("test script")	
	
          -- define locals
          local dx,dy = 0,0
           
          -- get position modificators, to find cell in front of the party
          if party.facing == 0 then dy = -1
          elseif party.facing == 1 then dx = 1
          elseif party.facing == 2 then dy = 1
          elseif party.facing == 3 then dx = -1
          end

          -- check what is in front of the party      
          -- interate through all objects on cell
          for e in party.map:entitiesAt(party.x + dx, party.y + dy) do
      					
			--print (e.id)
			--print("check Cell")
			
           	if e == nil then
				playSound("party_dig") 
				hudPrint("Digging...")
				GameMode.fadeOut(0x0,1.5)     
			 	timer_foundNothing.timer:enable()
				
			end
			
           if e.id == "invisible_platform_diggout" then 				
			playSound("party_dig") 
			hudPrint("Digging...")
			GameMode.fadeOut(0x0,1.5)
			timer_digExtra.timer:enable()		
               else
	 		playSound("party_dig") 
			hudPrint("Digging...")
			GameMode.fadeOut(0x0,1.5)     
			timer_foundNothing.timer:enable()	
             end             
	  end
end

Right, so if there are no items in the cell then there is no "e" based on your code. On the opposite side of that equation, because "e" is a placeholder for any and all items on the cell, your Dig Code will continue to execute for every "e" in that cell.

What I would do using your approach:

Situation A) If you only want to allow digging on certain tiles:

1) Pick one Game Object that you will always use to represent a "dig spot." Let's choose the Forest Altar for this example.

2) Put a Forest Altar in the spot where you want digging to occur. Remove all Component properties (clicable, obstacle, projectcollider, model). Give it a unique ID, dig_spot_1.

3) In your "e" loop replace "if e == nil" with, "if e.id == dig_spot_1"

4) Your script will trigger digging every time you hit a "dig spot" altar. You can get fancier with the script to avoid hardcoding the number at the end of the dig_spot_


Situation B) If you want to allow digging in all unique tilesets

1) Only allow digging if there are absolutely no objects in that tile. Add a variable to your function, local itemCounter = 0

2) Inside your "e" loop simply increment it: itemCounter = itemCounter + 1;

3) Optionally, as soon as "e" evaluates once (ItemCounter becomes 1), enter a "break;" command to stop the loop.

4) If ItemCounter is greater than 0 then inform the user that there is something not allowing them to dig: hudPrint("You can't dig here at this time")

5) At the end of the function allow digging only if itemCounter is still 0; "if itemCounter == 0 then DoDig();"

6) You won't need the "if e == nil" line at all in this scenario


Not sure if this is exactly what you're needing, but based on what I understood this is most likely what I'd do. Hope it helps!

Hi Azel - thanks for the reply.

I am not at home at the moment so I can't try out your suggestion. But I will do later in the evening.

Anyway - my digging-script must work in all 3 cases:

1 - there is an empty tile in front of the party -> digging and finding nothing
2 - there are objects/items in front of the party -> digging and finding nothing
3 - there is my special target in front of the party -> digging and finding bonus

To differentiate between 1 and 2 is not nessecary - it is just a fact, that my script-approach reacts different in this two cases. At least if I don't tell it somehow to do not...

[Azel]

This should do it:

Code: Select all

function diggingTHOM(self)
	-- define locals
	local dx,dy = 0,0;		
	local digExtra = "false"

	-- get position modificators, to find cell in front of the party
	if party.facing == 0 then dy = -1
		elseif party.facing == 1 then dx = 1
		elseif party.facing == 2 then dy = 1
		elseif party.facing == 3 then dx = -1
	end

	-- check for digExtra location
	for e in party.map:entitiesAt(party.x + dx, party.y + dy) do

		if e.id == "invisible_platform_diggout" then             
			playSound("party_dig")
			hudPrint("Digging...")
			GameMode.fadeOut(0x0,1.5)
			timer_digExtra.timer:enable()
			digExtra = "true"
			break;
		end
	end
	
	-- if not digExtra, show nothing
	if digExtra == "false" then
		playSound("party_dig")
		hudPrint("Digging...")
		GameMode.fadeOut(0x0,1.5)     
		timer_foundNothing.timer:enable()
	end
end
