Did a short little script to allow my bot to look like any prop its standing next to.

Still a lot of work to do on this concept, but at least the hard part is done.

Resin

Jip

I absolutely love it

Resin_Smoker

@jip Thanks! Will tie it into to units movement and its attack. So it could remain unseen until it moves are fires. Which will force it to decloak. Figured this would be way cooler than just another phase mesh swapout.

Resin_Smoker

Woot got everything working! I love having the terrain specific stealth.

Resin_Smoker

Updated the script above. Only need to have the weapon charge timer (RenderFireClock) display correctly. Currently it works off of the weapons rate of fire but as this unit must charge to fire, I need to make something custom for it to display correctly.

Resin_Smoker

OK here is a proper fire clock that uses the weapons energy drain as its basis.

OnCreate = function(self,builder,layer)
	AWalkingLandUnit.OnCreate(self)
	self:DisableIntel('Cloak')
	self.CamoEntity = nil
	self:SetWorkProgress(100)
end,
	
RenderChargeClockThread = function(self, eRequired, eDrain)
	local clockTime = math.round(10 * (eRequired / eDrain))
	local totalTime = clockTime
	while clockTime >= 0 and not self:BeenDestroyed() and not self:IsDead() do
		self:SetWorkProgress(1 - clockTime / totalTime)
		clockTime = clockTime - 1
		WaitSeconds(0.1)
	end
end,

Its called from the weapons PlayFxMuzzleSequence via...

	-- Reset the units reload bar
	local eDrain = self.EnergyDrainPerSecond
	local eRequired = self.EnergyRequired
	self.unit:ForkThread(self.unit.RenderChargeClockThread, eRequired, eDrain)

While it does work, I've noticed that there is a short delay between when the clock finished and when the weapon fires. I'm thinking that the weapons internal reload may have some delays involved that don't show properly in the units UI. Currently the unit shows as 10 seconds but with that delay I'd say its more like 11 seconds.

IndexLibrorum

Not making this part of the Cybran faction is a criminal oversight, however.

Resin_Smoker

@indexlibrorum IKR... Anyways, I've been pondering making the script into a superclass, so it can later be applied to other units quickly. Including the nasty Cybrans.

Resin_Smoker

@indexlibrorum

Ok made the script into a SuperClass so it can be easily added to other units, including your Nasty Cybrans!

### End of TerrainCamo(SuperClass) ###

Resin_Smoker

I've added this ability to the 4DFAF URL0216 Insurgent and will remove it from the Predator. It will instead have a custom unit mesh for cloaking. (need to make it)

Resin_Smoker

Made some improvements to the Terrain Camo. It now has a phase out effect before the units takes on the mesh of the nearby trees.
