Blood Decals

[Slimwaffle]

I need help with blood decals for my game. They are loading in fine. But they are square looking patches and the keep flickering and vanishing.I have tried everything I can think of. And the fact that I can't see a preview in the material editor isn't helping. I will provide a screen shot and the code I am using. Ideally I would like them to look like pools of blood. And not vanish at all. So that I can create a whole other script that dictates how long to wait before vanishing.

--Moving Check
	if self.mode == "roam" then
	self.moving = 1
	elseif self.mode ~= "roam" then
	self.moving = 0

	end
	--Foot step sound
	if self.moving == 1 then
	if self.sound.foot ~= nil then
	self.footdelay2 = self.footdelay2 - 1
	if self.footdelay2 <= 0 then
	self.entity:EmitSound(self.sound.foot, 30 , 1 , 1 , false)
	self.footdelay2 = self.footdelay
	--Blood Texture for ground
	if wounded == 1 then
	--Bullet mark decal
	
	
			
			--Bullet mark decal
			local mtl
			local scale = 0.1
			
				mtl = Material:Load("Materials/Decals/wound.mat")
			end
			local decal = Decal:Create(mtl)
			
			--decal:SetScript("Scripts/Objects/Effects/BulletMark.lua")
			
			decal:SetColor(1,0,0,1)
			decal:SetPosition(self.entity:GetPosition())
			decal:SetParent(terrain.entity)

			
			

	
	
	end
	end
	end

I assume you copied all the tex and mat settings from a decal in the Materials/Decals folder and that you've verified your png has transparency?

[Slimwaffle]

yeah pretty much exactly what happened.

As an alternative until I can fix this. I have made a prefab box with one surface textured to the blood. This has transparency and works perfectly (using the same material) and fixes all issues at once.I would like to however get this working with decals. Because scene overload from too many scripted prefabs is a big issue with my game. Every time I make something new I have to find ways to balance it.

If you want to upload the whole thing (png, tex, mat) or a test that also didn't work, I'll take a look at it.  Also, just a heads up that I haven't really looked at your code because I don't use Lua.

[Slimwaffle]

The material and texture are the default ones for wound. That come with leadwerks. And the only code I had to reference it was the code I used above.

Aren't you setting the color of your decal to red?

decal:SetColor(1,0,0,1)

 

Looking at the Projectile.Lua script

local decal = Decal:Create(mtl)
            decal:AlignToVector(pickinfo.normal,2)
            decal:Turn(0,0,Math:Random(0,360))
            decal:SetScript("Scripts/Objects/Effects/BulletMark.lua")
            if mtl~=nil then mtl:Release() end
            decal:SetPosition(pickinfo.position)
            decal:SetParent(pickinfo.entity)

You might like to add decal:Turn line to your script so that the blood looks more natural.

Hope this helps.

If I don't set it to red then it just shows grey squares instead.

Have you looked at this thread?

Yeah that was one of the first ones I read.
