Crash when trying to change the effectiveness of tools


Recommended Posts

Hi everyone,

I'm getting a crash when I'm trying to change the effectiveness of a tool.

I made my own component do to this, the strange thing is that for tools with only the action chopping there is no crash, for everything else it crashes (see crashlog in spoiler).

function Mod_Modifier:AddModifierTool()
	local mod = string.upper(tostring(self.modifier))
	if self.inst.components.tool then
		if self.inst.components.tool:CanDoAction(ACTIONS.CHOP) then
			local old_eff = self.inst.components.tool.actions[ACTIONS.CHOP] 
			if old_eff then
				self.inst.components.tool:SetAction(ACTIONS.CHOP, old_eff * TUNING_MELANIE.MODIFIERS[mod]["TOOL"]["CHOP"]* 1.5)
			end
		end
		if self.inst.components.tool:CanDoAction(ACTIONS.NET) then
			local old_eff = self.inst.components.tool.actions[ACTIONS.NET] 
			if old_eff then
				self.inst.components.tool:SetAction(ACTIONS.NET, old_eff * TUNING_MELANIE.MODIFIERS[mod]["TOOL"]["NET"]* 1.5)  <--------here is the crash
			end
		end
	end
end

I also tried it by changing the effectiveness directly like this, but the same thing:

self.inst.components.tool.actions[ACTIONS.NET] = old_eff * TUNING_MELANIE.MODIFIERS[mod]["TOOL"]["NET"]

 

If someone has an idea of what I could try or why it doens't work, please let me know.

Thanks in advance,

Monti

This mean that when the game tries to access ".NET" from something, it was not declared

So

 TUNING_MELANIE.MODIFIERS[mod]["TOOL"]["NET"]

This is not declared
If you try to print it you will see it its "nil"

THANK YOU SO MUCH!

I was really frustrated as I couldn't find the error, I didn't even think of checking my tunings!

I was so focused on thinking that it had problems to find the ACTIONS.NET that I didn't thought of my other NET variable...

Lesson learned!
