Short description: This mod adds some weird blocks on which you can not walk but you can point and build to them. They act in surprising and unexpected ways.

OK, this is a weird mod intended to aid in more complicated construction projects and maybe for some simple puzzle maps. It takes some time to explain this mod. Maybe it is best if you just try it for yourselves!
This mod adds some so-called “pseudo-blocks” to Minetest and a pseudo-pickaxe.
A pseudo-block is a block on which you can not stand, but you can see through and point to it.
Let me introduce several pseudo-blocks:
Pseudo-block:
You can build it, but you can not collide with it. But you can point to it and you can build stuff to it as if it were a solid block. It gets even more weird: Liquids can rest on a pseudo-block as well.
Pseudo-blocks have a black-and white edge.
This screenshot shows 3 pseudo-blocks stacked on each other. On top I placed a desert stone:

A variant of the pseudo-block is the timed pseudo-block. This behaves exactly the same, but it disappears 5 seconds after you placed it. Useful if you don’t want to remove all those pseudo-blocks manually. Here’s an example:

5 seconds later:

A different kind of pseudo-block is the replacable pseudo-block. It has a yellow/red edge.
This block is very weird. If you attempt to build stuff next to it, instead the block itself gets replaced:


The replacable pseudo-block comes with a timed variant as well.
Lastly, I added more a “gimmick” block, which is the switch block.
A switch block can have one of 2 states: on and off.
If on state, it is a solid block, but in off state, it behaves like a pseudo-block. Here is how solid blocks look like:

If you rightclick it, you switch the state of the block. You have to press [sneak]+[right click] to be able to build next to it.
Here are some more quirks shared by all those blocks: All those pseudoblocks do not act like normal blocks and can not be destroyed by normal means. The can be destroyed if you are in posession of the pseudo-pickaxe. This is a special tool which can destroy the pseudo blocks, but nothing else! Once a pseudo-block is placed, you can not get it back, only destroy it.
For convenience, all the blocks can be stacked up to 9999 times in the inventory, which is much larger than the default 99. Also, explosions do not affect the blocks. With one exception: A activated switch block gets turned off (not destroyed) by an explosion, because I thought this is funny.
Because these blocks act rather strange, it is not planned to add normal means to obtain these nodes. Get them in creative mode or use /giveme with these itemstrings:
- pseudonodes:pseudo_block
- pseudonodes:pseudo_block_timer
- pseudonodes:replacable_pseudo_block
- pseudonodes:replacable_pseudo_block_timer
- pseudonodes:switch_block_off
- pseudonodes:switch_block_on
- pseudonodes:pick
Technical notes for modders: This mod assumes that explosion mods call the function on_blast properly. This is not a function I pulled out of my ass, this is part of the official lua_api.txt documentation. If you created a mod with explosions, please consider calling this function instead of just removing all the nodes directly.
All the blocks are in the group “pseudo” and the pseudo-pick only destroys things in this group. Simple as that so it can be easily extended.
Okay, that’s all about to say about the mod. Feedback is appreciated. If you have ideas for other “weird” nodes which act in strange ways but may be somehow useful, please let me know.
