During one of my fights I'm looking to darken the screen of the player to make it harder for them to see. Just making the room dark doesn't work right since we have a soft natural blue glow that gives some light to the party. Anyone know of a script I could run during a fight that would just darken up the screen some more?

I don't think this is a good idea in the first place, since your players' displays are going to have varying brightness levels, and what's "hard to see" is going to vary a great deal between them. Also, the way Grimrock renders shadows has an extreme color depth problem such that sufficiently dark places are going to look awful - or be completely black - anyway.

But that aside, in Grimrock 2 that blue glow is from a LightComponent attached to the party object named "torch". You can disable it and add your own LightComponent with the brightness/color/etc that you want. (Changing the brightness/color of torch doesn't work very well because the game just overwrites it with new values immediately.)

Someone will probably suggest drawing a translucent rectangle in PartyComponent.onDrawGui, but onDrawGui doesn't execute if the player is free-looking, the game is paused, etc., which makes it pretty unsuitable for this sort of thing.

Just spawn some Dark Bolts, it does a great job of darkening the screen. I like to spawn the occasional eyctopus, who casts Dark Bolt by default.

Minmay or anyone:
I need an example of this lightsource torch thing: cant seem to find it in the scripting reference ... what and how do I need to change class "light" to get a darker lightsource?

defineObject{
name = "party",
components = {
{
class = "Party",
},
{
class = "Light",
name = "torch",
range = 12,
},
},
editorIcon = 32,
placement = "floor",
}

Here is the code for the Torch particle (the "glow" section is in it) :

Code: Select all

defineParticleSystem{
	name = "torch",
	emitters = {
		-- smoke
		{
			emissionRate = 5,
			emissionTime = 0,
			maxParticles = 50,
			boxMin = {-0.03, 0.1, -0.03},
			boxMax = { 0.03, 0.1,  0.03},
			sprayAngle = {0,30},
			velocity = {0.1,0.5},
			texture = "assets/textures/particles/smoke_01.tga",
			lifetime = {1,1.75},
			color0 = {0.15, 0.15, 0.15},
			opacity = 1,
			fadeIn = 0.5,
			fadeOut = 0.5,
			size = {0.3, 0.6},
			gravity = {0,0,0},
			airResistance = 0.1,
			rotationSpeed = 0.6,
			blendMode = "Translucent",
		},

		-- flames
		{
			emissionRate = 50,
			emissionTime = 0,
			maxParticles = 100,
			boxMin = {-0.03, -0.03, 0.03},
			boxMax = { 0.03, 0.03,  -0.03},
			sprayAngle = {0,10},
			velocity = {0.2, 1},
			texture = "assets/textures/particles/torch_flame.tga",
			frameRate = 35,
			frameSize = 64,
			frameCount = 16,
			lifetime = {0.25, 0.85},
			colorAnimation = true,
			color0 = {2, 2, 2},
			color1 = {1.0, 1.0, 1.0},
			color2 = {1.0, 0.5, 0.25},
			color3 = {1.0, 0.3, 0.1},
			opacity = 1,
			fadeIn = 0.15,
			fadeOut = 0.3,
			size = {0.35, 0.015},
			gravity = {0,0,0},
			airResistance = 1.0,
			rotationSpeed = 1,
			blendMode = "Additive",
			depthBias = 0.1,
		},

		-- glow
		{
			spawnBurst = true,
			emissionRate = 1,
			emissionTime = 0,
			maxParticles = 1,
			boxMin = {0,0,-0.1},
			boxMax = {0,0,-0.1},
			sprayAngle = {0,30},
			velocity = {0,0},
			texture = "assets/textures/particles/glow.tga",
			lifetime = {1000000, 1000000},
			colorAnimation = false,
			color0 = {0.23, 0.11, 0.08},
			opacity = 1,
			fadeIn = 0.1,
			fadeOut = 0.1,
			size = {2, 2},
			gravity = {0,0,0},
			airResistance = 1,
			rotationSpeed = 0,
			blendMode = "Additive",
			depthBias = 0.1,
		}
	}
}

...That is completely and utterly unrelated to everything in this thread. We're talking about the LightComponent on the party called "torch". Not the particle system that happens to be called "torch" or the object that happens to be called "torch".

It's just a regular LightComponent like any other, with the exception that the game changes its brightness/color/range automatically every frame. You can find the LightComponent methods here, but again, you probably just want to disable torch (just use the disable() method that all components have) and add your own LightComponent instead, because you can't usefully change the brightness/color/range of torch.

mmhhmm, is it one specific thing or is it like any other thing? lol

I posted it because it has script for addressing the color and frame properties which may help kelly1111 in her task. It may not, but it is certainly far from "completely and utterly unrelated to everything in this thread." Although I do like how you completely and utterly contradicted yourself.

Ffs. A particle system is not a LightComponent. It's not even a component. None of those fields correspond in any useful way to any field on any component, let alone LightComponent.

Do you mean to say that the frame and color properties of the Particle System cannot be applied to a Light Component?
