Character producing items

[icantevenname]

The mod I'm working on at the moment is the Sunflower from Plants Vs. Zombies. More specifically her Garden Warfare appearance. I feel like keeping her medic capabilities, and I want to do that by having her drop healing suns every now and then. I'm sure I can figure out making the suns, but I have no idea how to have her drop suns regularly. Any pointers please?

[IronHunter]

You'll probably want to look into making a DoPeriodicTask(time, function) that is called at the interval you want it to drop suns.

The function you are calling will drop the suns.

If you need more in depth assistance just ask.

This goes under that master_postinit thing, right?

By time, is it an already set increment, or do I have to set a specific increment as well as a number? Like seconds, minutes, in-game days?

And for function, do I put in drop_sun, or spawn_sun, or something like that?

Assuming you are using the sample_character template:

You can do something like this:

Spoiler

local function spawnitem(quantity, prefab, location)
	local quantity = 1
	if quantity > 0 then
		for i = 1, quantity do
			local item = SpawnPrefab(prefab)
			if item ~= nil then
				local x, y, z = location.Transform:GetWorldPosition()
				if item.Physics ~= nil then
					local speed = 2 + math.random()
					local angle = math.random() * 2 * PI
					item.Transform:SetPosition(x, y + 1, z)
					item.Physics:SetVel(speed * math.cos(angle), speed * 3, speed * math.sin(angle))
				else
					item.Transform:SetPosition(x, y, z)
				end
				if item.components.propagator ~= nil then
					item.components.propagator:Delay(5)
				end
			end
		end
	end				
end
local function onbecamehuman(inst)
	inst.sunTask = inst:DoPeriodicTask(5, spawnitem(1, "sundrop", inst))
end
local function onbecameghost(inst)
	if inst.sunTask ~= nil then
        inst.sunTask:Cancel()
        inst.sunTask = nil
    end
end
local function onload(inst, data)
    inst:ListenForEvent("ms_respawnedfromghost", onbecamehuman)
    inst:ListenForEvent("ms_becameghost", onbecameghost)
    if inst:HasTag("playerghost") then
        onbecameghost(inst)
    else
        onbecamehuman(inst)
    end
end
   

 

Ok to explain: inst:DoPeriodicTask(time in seconds, function that is called when that amount of time passes)

The spawnitem thing is something I use for a bunch of stuff in my mod as a catch all useful thing.

I can explain in more detail, but hopefully you should be able to decipher the rest.

This is to help get you in the right direction, hopefully you can modify it from there to your needs.

I'm confused, I put in the code, just changing "sundrop" to "meat" (I wanna see if the code works before I make the suns.) I waited around for at least an in-game day and nothing happened. I died and revived and dropped meat. I died multiple times and each time I revived, I dropped meat.

Please post your characters code so that I can see how you are integrating the code with the character template.

Merged your become human and become ghost functions and also fixed the DoPeriodicTask it requires a function to call the spawn the function. Works fine for me

Cheers

Thanks alot! Now to make the suns. I bet I'll be fine doing that. Thanks again!
