With this mod, you can use the spawn commands from Block Display in Survival Mode.
The mod adds two new items:
Spawnegg
The Spawnegg allows you to enter and execute summon commands.
Right-clicking with the Spawnegg opens the command prompt, where you can enter your command.
You can also give the Spawnegg a custom name:
Name /summon_command
Only names without whitespaces are allowed.
Debug Stick
The Debug Stick is used to rotate and remove spawned models.
Pressing F3 + B shows the hitboxes of the spawned models. You can use the Debug Stick to rotate or destroy models inside these hitboxes.
Multiple Models
You can summon multiple models on the same block.
Be aware that using the Debug Stick will rotate everything inside the hitbox. Some summon commands consist of multiple separate models, which means they may be affected together.
If you want to rotate only a single model, make sure it is placed seperately from other models or on top.
By holding Shift and right-clicking with the Debug Stick, you can rotate only the topmost model inside the hitbox.
