Item Fountain Line

The same as the Fountain Line effect, but with dropped items instead of falling blocks.

Parameters

Parameters	Information	Example
FromLocation	The start location of the fountain in the format of world, x, y, z.	world, 196.3, 64, -381.8
ToLocation	The location it moves towards in the format of world, x, y, z.	world, 201.3, 64, -381.8
Velocity	Sets the velocity of the dropped items. This is used to launch items in a specific direction. Don't set these values too high (I would say around a maximum of 10). Follows the pattern of x, y, z.	1, 1.5, 0
Material	he material to use as item. All items work here!	NETHER_STAR
CustomModelData	The custom model data of the item (if you want to use custom models).	12
Lifetime	The amount of time the dropped items should stay visible. After this time (in ticks) they'll be removed.	40
Randomizer	This randomizes the value of the velocity a bit. The higher the value, the more the velocity changes. I suggest keeping this between 0 and 1.	0.5
Speed	The speed the origin moves from the first location to the second one. Measured in blocks/s	5
Frequency	In Minecraft a new entity or particle spawns every tick, but when the speed is very high an empty space comes between two entities or particles. To fix that you can use the frequency parameter. The frequency is how many entities/particles there should be every block. This effect only activates when the speed is too big that the amount of entities or particles per block is lower than the frequency.	5
Delay	The amount of ticks this effect waits after the show starts before it's activation.	40

Frequency extra info

In Minecraft a new entity or particle spawns every tick, but when the speed is very high an empty space comes between two entities or particles. To fix that you can use the frequency parameter. The frequency is how many entities/particles there should be every block.

This effect only activates when the speed is too big that the amount of entities or particles per block is lower than the frequency.

An example is when a particle line travels 10 blocks forward with a speed of 1 and a frequency of 5. The frequency will not be activated because the speed is 1 block per second which means that there will be 20 particles on one block and 20 is bigger than 5. If we change the speed to 10 then it'll travel with 10 blocks per second. Meaning that there should normally only spawn 2 particles on every block! This is where the frequency kicks in to spawn extra particles to fill in the gap.
