Ask a simple question, get a simple answer

It is not possible to remove items from SurfaceComponents or SocketComponents except by destroying the items or getting the player to click on the items and pick them up. Attempting to remove an item from one of these components via script (by destroying the Surface/SocketComponent, adding it to another surface/socket/inventory, using setMouseItem(), etc. etc.) will cause the savegame to permanently break and crash when the player tries to load it.

... But you can construct a duplicate of the item; as in the case of [seeming to move] item stacks, and custom magical items with partially used charges.

I need ask a grimtk related question, I will post here but link it in the grimtk thread.

If this is an easy thing and Ive just missed an obvious fix - pls correct me...
OK the issue is mouse clicking through grimtk windows / widgets .... and in doing so >> activating things from the vanilla game that I definitely do not want activzated (eg attack panel weapon swap buttons)
Ive read into (but am still not totally comfy with) the code from grimtk's script files.... I had suspected for a while that I could do some fancy widgetStack manipulation - but vanilla buttons don't register when grimtk checks and builds the widgetStack (any widgets directly underneath the mouse cursor). I also noticed but blanked on some of the mouse methods / fields such as:
self.visitWidget = function(self, gContext, widget)
self.commit = function(self)
self.mouseFocus
Im not entirely sure how these things interact - if anyone has an explanation of this that a cat could understand, pls send it my way

So, re-worded, my question is:
Can we prevent the mouse clicking through grimtk windows & widgets (and cease iatrogenically activating vanilla buttons / menu stuff) ??

Artifacts of might: dm_resource_log2 asset pack has a particle called dm_waterdrops that's used in a cave-in ceiling
I'd like to make a placable object of these waterdrops to create a nonintrusive rain effect
I have the entire pack in my mod.

Code: Select all

defineParticleSystem{
	name = "dm_waterdrops",
	emitters = {
		{
		emissionRate = 16,
		emissionTime = 0,
		spawnBurst = false,
		maxParticles = 64,
		boxMin = {-1.0,-1,-1.0},
		boxMax = {1.0,5,1.0},
		sprayAngle = {178,180},
		velocity = {8,10},
		texture = "assets/textures/particles/glitter_silver.tga",
		lifetime = {1, 4},
		colorAnimation = false,
		color0 = {0.42, 0.56, 0.7},
		fadeIn = 0.5,
		fadeOut = 0.5,
		size = {0.01, 0.02},
		gravity = {0,-12,0},
		airResistance = 5,
		rotationSpeed = 2,
		blendMode = "Additive",
		depthBias = -0.001,
		clampToGroundPlane = true,
		},
	}
}

I was looking at the defineobject snow code from the winter set to make a similar object.
But I'm not sure how to proceed.

Code: Select all

defineObject{
	name = "sx_snow_particles_1square",
	
	
   components = {	
	  {
         class = "Model",
         model = "mod_assets/sx_winter_tileset/models/sx_blocker.fbx",
      },  	
      {
         class = "Controller",
      },	
	 {
         class = "Particle",
		 ParticleSystem = "sx_snow_emitter_1x1",
		 --debugDraw = true,
      },
	
   },

   placement = "floor",
   replacesFloor = false,
   editorIcon = 136,
}

into

Code: Select all

defineObject{
	name = "waterdrops1",
	
	
   components = {	
	 {
         class = "Particle",
		 ParticleSystem = "dm_waterdrops",
		 --debugDraw = true,
      },
	
   },

   placement = "floor",
   replacesFloor = false,
   editorIcon = 136,
}

Would this work?

1) Is there a way to add a chance for a throwing item or missile ammo to convertToItemOnImpact ? Setting it to "true" always converts it, but I need a slight chance only for it to happen (e.g. attrition).

Code: Select all

onThrowAttackHitMonster = function(self, monster)
	if math.random() < 0.8 then
		monster:setCondition("poisoned", 20)
	end
	end,

2) Fiddling with skill points via onEquipItem and onUnequipItem is bad, I know. How could I at least prevent the 5th skill point from getting removed when unquipping the item with a maxed out skill (concentration lvl 5)? Permanent removal of a skill point seems pretty bad.

Code: Select all

			onEquipItem = function(self, champion, slot)
				if slot == 1 or slot == 2 then
				champion:trainSkill("concentration", 1, false)
				end
				end,
			onUnequipItem = function(self, champion, slot)
				if slot == 1 or slot == 2 then
				champion:trainSkill("concentration", -1, false)
				end
				end,

Hey Pompidom,
Ive used this texture file from the winter tileset

Code: Select all

 texture = "mod_assets/sx_winter_tileset/textures/sx_raindrop_fx.tga",

I add this component to my party object:

			name = "rain",
			particleSystem = "sx_rain_emitter_party_square",
			onInit = function(self)

and this is the definition for the particle system (as well as an object def):

You can turn the rain off and on with

Code: Select all

party.rain:enable() 
party.rain:disable()

Hope this helps!

NOTE** You will need to make arrangements for handling when the party is undercover but looking out at an area with rainfall

Lorial,
Cant help with (1) but for (2), this is what you are looking for.
There are links to scripts that will manage traits and stat adding and removing too

This rock becomes gravity-less when thrown or launched.
But you can also do something when it lands, e.g. destroy the rock and create a new item at the rock's location.
The code works even when you set:
sharpProjectile = true

How would you go about using multiple auto map icons for an object? Like water for example.

[Isaac]

How would you go about using multiple auto map icons for an object? Like water for example.

As in one object that changes state, and this is reflected on the automap?
Or do you mean that each object [randomly?] picks its icon from a table?
