You have entered a secret page!

Just kidding. During the update process of Vanilla Library, we found that there is no suitable place for storing some time-sensitive and detailed information in the library. Therefore, we plan to add a page in "feature" to put some miscellaneous information. Updated with the "feature" update. The content of this page is not fixed, it may be various information, such as command questions and answers, trivia, ~~data pack jokes~~, etc. We have also added a discussion area for this journal at the bottom of this page. You can express your views on this issue of "Feature" below, and you can also ask us questions.

TIP

This section posts new posts recently included in the library, replacing the original "Recent Updates" page.

Eliminate the automatic coordinated attack behavior of wolves

As one of the entities that can actively follow the player, the wolf is very effective when making some following systems (such as automatically following robots). But we don't always want it to automatically attack skeletons or mobs that the player is attacking. Therefore we can modifyfollow_rangeto eliminate hostile behavior.

Use the specified wolf as the executor to execute the following commands frequently:

mcfunction

execute if data entity @s AngryAt run attribute @s follow_range modifier add anger -1 add_multiplied_total
 
execute unless data entity @s AngryAt run attribute @s follow_range modifier remove anger

This command works by lowering the wolf's aggro target by lowering itsfollow_rangeattributes to eliminate the hate target, and restore the attributes after the target is eliminated to retain its following and pathfinding capabilities.

Fast rough radiographic inspection

It only takes effect on the entity. The simulation emits a ray towards the entity at a certain position. The entity hit by the ray says you have discovered it. No recursion, good performance, average but acceptable accuracy

MC explosion momentum calculation formula

Explosion intensity = 1-distance from explosion center to entity/explosion diameter Explosion momentum = unit vector from explosion center to entity eye * explosion intensity
