Thanks for the (first) hints. The block I wanted to use in the circular saw was not from SciFi-Nodes.
But now ... I tried to understand the example-code in SciFi-Nodes and tried to register a block in an own mod to use it in the circular saw of "moreblocks".
In the mod the block is defined as ...
minetest.register_node("startest_decorative:floor_blue", {
description = "Floor blue",
tiles = {"spaceship_floor_blue.png","spaceship_wall_basic.png","spaceship_wall_basic.png","spaceship_wall_basic.png","spaceship_wall_basic.png","spaceship_wall_basic.png"},
groups = {cracky = 1, wood = 1},
paramtype2 = "facedir",
})
Follwing the instruction in the API documentation for Stairs+ I have this code in init.lua.
if minetest.global_exists("stairplus") then
stairplus:register_all("startest_decorative", "floor_blue", "startest_decorative:floor_blue", {
description = "Floor blue",
tiles = {"spaceship_floor_blue.png","spaceship_wall_basic.png","spaceship_wall_basic.png","spaceship_wall_basic.png","spaceship_wall_basic.png","spaceship_wall_basic.png"},
paramtype = "light",
groups = {cracky = 1, wood = 1},
light_source = 0,
paramtype2 = "facedir",
})
end
There is no error and the games starts, but the block is not accepted.
What needs to be changed.
