FOSS gamedev and creative worlds

Hi, there is my first mod from scratch. The idea was born during studying the WorldEdit Code how to hide blocks.

Description:
The mod contains a tool that allow you to go trough blocks. If the tool is active you are in a Subspace bubble, so the real blocks around you are not there and you can walk trough them.
How to use:
- You need to hold the Subspace Walker tool in the hand and use them (right-click) for activation.
- Sneaking results in a lower Subspace and you go downwards.
- Jumping bring the nodes below you back to outside Subspace so you can go upwards
-To disable the Subspace Walker Tool just try to place it (left click) or take something other in the hand
- The tool can be crafted in as a vertical stick:

default:diamond
default:mese_crystal
group:stick

Configuration
At begin of the "init.lua" some parameters can be adjusted

you should rename to shadowstep with a dark foot as icon

Thank you for your proposal. It is better then subspacewalker that I cannot remind by myself.
If I search for "shadowstep" I find only WoW related information. Any other proposal for a name that is more known as a WoW card?

For an Icon: it should be a tool that the player hold up in the hand. In my opinion something like a decorative stick (fantasy-like / recipe: stick+diamond+mese in vertical?) or a technical device (SciFi-like). But I cannot paint both :(

i can paint you that. to be honest i didn't known it was a world of warcraft kard :D

here you go!

Thank you! License of the image?

I added a recipe and take an adjustment (pointable = false for subspace-nodes). For now I think I can release the mod.

wtfpls license :)

Let's say it's CC0

not good for servers, not for single player ether if you have privs on single player than why would you need this
it will be good fro creative servers (maybe) good mod tho

Can you explain why it is not good for servers or single player? The idea was it will be nice on survival servers to avoid tunnelling in searching for caves, but without the full "noclip" functionality/permission.

well if you dont have the noclip permision, with this thing you can do it, what is the point tho? if you dont have the noclip priv is because the adminitrator doesnt want you to

This is pretty cool, but I imagine this creates much lag? With constant replacement of blocks?

I noticed some visual lag but the reason is probably my slow onboard graphics chip. So you can try the mod and tell me about your experience.

There is no constant replacement of blocks. A globalstep checks nodes nearly active subspacewalker and swap the nodes to the subspace. Already swapped to subspace are not touched again. So if you stay, the mod should do nothing. The globalstep is limited to 0.25 seconds (4 times per second).
A abm on subspace nodes checks if no active subspacewalker is nearly and then swap the nodes back to original. The interval is more frequently (0.1) but with longer interval the going up trough jumping does not work proper.

Shadowstep is also a skill from the Dual Sword skill tree in Toram Online :P
it's a flashy ninja attack and you are invincible while casting it.

Today I updated the mod. The main goal was to get to know VoxelManip. For now the subspace does less flicker. There are some optimizations in processing intervals, that should spare the CPU.

To be more server friendly there is a new "restricted" mode enabled by default. In this mode the walker cannot be used for housebreaking because only the compatible nodes (dirt and stone) can be transformed to subspace. The first screenshot is in this mode now.
The restore does some randomization. If you don't like it you need to set the c_randomize_restore to 1.

Question to other developers: This mod update is my first experience with VoxelManip interface. So please tell me all miss-usages in code. The metadata handling is still using get_node/get_meta, the restoral is still using swap_node. Is there a way to change them to VoxelManip too or is the current way the right one?

A gameplay related update: Added wear to the subspacewalker tool depending on transformation count. Now the tool transforms only 65535 nodes. On default size that are ~ 1000 steps (which have gone faster than you think). So the tool does not give persistent capability to the player in survival.
