Say if I want to make like, a portal or what not, how would I make the lil portal bits so that you can walk through it?

I just started with lua scripting...and have been looking at some mods, and they all use node, but you can't walk through nodes...can you?

Yes, you can walk through nodes.
Just add this to your node definition:

walkable = false,

Oh thank you! Now one more question...I been messin wit it only for like an hour now, but think I'm understanding a bit now.

I'm currently looking through more_ores mod and have stumbled across this...

Edited this part: Alright good thanks guys for this, but theres still more under this now! :/

and how could I make it so I could obtain the node upon hitting it once with anything? O.e

Sorry, working on a flower mod so thats why I asked for the walkthrough as well. xD

This is what I got so far... still need help though xD

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: --[[ **** Flowers by Lunarhiro Version 1.0 **** --]] -- Flowers minetest.register_node( "flowers:flowers_flower_red", { description = "Red Flower", tile_images = { "flowers_flower_red.png" }, walkable = false, inventory_inventory_image = minetest.inventorycube( "flowers_flower_red.png" ), is_ground_content = true, material = minetest.digprop_constanttime(0.5), drop = 'craft "flowers:flowers_flower_red" 1', }) -- Items minetest.register_craftitem( "flowers:flowers_flower_red", { description = "Red Flower", inventory_image = "flowers_flower_red.png", on_place_on_ground = minetest.craftitem_place_item, })

Now I also...need to know, how can I make it spawn on top of grass? And how can I place the flower like if it was an actual ...well node? When I right click to drop it, it just falls down onto the floor like if I dropped iron or something xD. Thanks ;D

its simple drop is what will go into your inventory
sorry if ive double posted i left this one mid response

BTW, the way the drop line is written is outdated, it should be written like this in the newest version of minetest:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: drop = 'flowers:flowers_flower_red 1'

EDIT: And it's inventory_image, not inventory_inventory_image. Are you sure you want to have an inventorycube there?

Yea, I figured that part on my own after it failed to load the game, and told me to check the debug.txt.

It said "no name: or ":"" provided...or something like that, so I looked around in other mods and found that, but still have trouble with spawning it on grass terrains and being able to place it. Sorry, I'm a newb to lua xD...and c...and all that other stuff. Just okay at Sadscripting O.e

Edit I never post in time! :(

OK, the spawning part is a bit tricky. Do you want them to be generated during world generation or should they grow randomly later on? You'd do the first with an on_generated callback and the second using ABMs. Perhaps you could look how the existing flowers mod does it, I think it also has some algorithm that prevents too many flowers from spawning next to each other.

Randomly appearing, that way they can always appear wherever, but on grass. Hm, So Ima get the mod and see what I figure out, if anything xD. Should I repost what I fixed and did to the whole script?

Edit:
o.e oh god, looking at all this...

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: local grow_blocks_on_surfaces = function(growdelay, grownames, surfaces) for _, surface in ipairs(surfaces) do minetest.register_abm({ nodenames = { surface.name }, interval = growdelay, chance = 30, action = function(pos, node, active_object_count, active_object_count_wider) local p_top = { x = pos.x, y = pos.y + 1, z = pos.z } local n_top = minetest.env:get_node(p_top) local rnd = math.random(1, MAX_RATIO) if (MAX_RATIO - surface.chance < rnd) then local flower_in_range = is_node_in_cube(grownames, p_top, surface.spacing) if (n_top.name == "air") and (flower_in_range == false) then local nnode = grownames[math.random(1, #grownames)] dbg('Adding node ' .. nnode .. ' (' .. pos.x .. ', ' .. pos.y .. ', ' .. pos.z .. ')') minetest.env:add_node(p_top, { name = nnode })

Kinda hurts not knowing what the hell is going on LOL xD. Im'a eventually figure this out with you guys helping like you are thankfully...unlike where I learned sadscripting where people would turn a cold shoulder...learned it mostly alone...and ended up teaching some. xD
