Script.SetWatchWeapon + ProjectileCreated

[PepeAmpere]

I found this script Script.SetWatchWeapon(weaponDef.id, true) is something like prerequisite for use of Call-in ProjectileCreated, where i can match the same weaponDef.id.

I did this in init part:

Code: Select all

function gadget:Initialize()    
	for id,weaponDef in pairs(WeaponDefs) do
		local wName = weaponDef.name
		if (wName == "darkswarm") then
			Script.SetWatchWeapon(weaponDef.id, true)
			bugWeaponID = weaponDef.id
		end
	end
end

And I plan to use something like this (bugWeaponID is global):

Code: Select all

function gadget:ProjectileCreated(projectileID, projectileOwnerID, projectileWeaponDefID)
	if (bugWeaponID == projectileWeaponDefID) then
		spSetUnitWeaponState(projectileOwnerID,2,"range",100)
	end
end

.. but when gadget is loaded, i get this error:

[f=0000000] Error: error = 2, LuaRules/draw.lua, error = 2, LuaRules/gadgets.lua, [string "LuaRules/Gadgets/0fix_bug5.lua"]:56: attempt to call field 'SetWatchWeapon' (a nil value)

Can you pls explain how this work and if this Script is the one i need for use of this call-in described on wiki like:

ProjectileCreated() --> "proID, proOwnerID, weaponDefID" Only called for weapons with SetWatchWeapon enabled

Try without Script?

does nothing :) it doesnt react any projectile :)

Code: Select all

function gadget:ProjectileCreated(projectileID, projectileOwnerID, projectileWeaponDefID)
	Spring.Echo(projectileWeaponDefID)
end

thx for link, but how this answers the main point of question, why the gadget load fails?

Code: Select all

function gadget:Initialize()    
	for id,weaponDef in pairs(WeaponDefs) do
		local wName = weaponDef.name
		if (wName == "darkswarm") then
			Script.SetWatchWeapon(id, true)
			bugWeaponID = id
		end
	end
end

.. but when gadget is loaded, i get this error:

[f=0000000] Error: error = 2, LuaRules/draw.lua, error = 2, LuaRules/gadgets.lua, [string "LuaRules/Gadgets/0fix_bug5.lua"]:56: attempt to call field 'SetWatchWeapon' (a nil value)

Btw, the id of weaponDef used as "script" parameter is 292 (=its defined)

Ok, can be the reason for this error the fact, i found another use of this Script.SetWatchUnit for the same weapon in different gadget?

check where it is located on the wiki
and note, you didn't mentioned the important thing here that makes it fail.

do you have a

Code: Select all

if (not gadgetHandler:IsSyncedCode()) then blub

in gadget?
So that SetWatchWeapon is not called in unsynced part, where it might not exist. (this might also be what jK means?)

[PepeAmpere]

yes, it seems thats what great person is trying to suggest.
