how to spawn particles in a line on the x axis at random?

Hello everyone, I need some urgent help, I am making a VFX particle graph for making fireworks. now I want them to spawn in a line on the x axis at random.
However there is no node for me to use, I have seen a brackeys video that tell me to use a node called Position ‘(line)’. However, I cant find any blocks with this name,I would really like some help on the matter.

link to the tutorial I followed:

Thank you in advance

Hi @RadilMahbub ,

There is a Line Position block; you can right click on top of your Initialize context and type “line”:

Note: make sure you are looking for blocks (i.e. on top of a context like Initialize) and not for nodes (i.e. when you click outside of the graph in an empty space).

Alternatively, you can also simply add a Set Position block and add a random number to it’s X axis. In this example, we are setting a position randomly between (-2,0,0) and (2,0,0):

Hope this helps!
