Code principle:

Detect Lightning Entity Generation and get its position;

Detect all the entities in the server, if there is a sand dropped entity if there is a sand in the Lightning entity;

Use a instruction to generate glass drops with instructions at the Lightning entity position, and set invulnerable: true to burn it without igniting the lightning;

Existing problems:

First, the function Foreach (entity => {} instruction execution function will be run three times

(Only one sand was hit by lightning, and three glass was generated.) The reason is guessed:

The minimum unit of the game is tick, and any change in the game is 1Tick as the smallest unit. In the event

1Tick = 3ms, so the incident was executed three times;

Second, the drop -off entity that is thrown together will be stacked together, and the function GetentITIES (). SIZE () The result is that the sand entity is only one;

Therefore, this method of lightning synthesis can only participate in the synthesis at a time, and many items can only be burned by the fire left by lightning;
