How do I assign a direction for a ray?

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I want to make a bottle that spills water after being thrown and hitting something.

  2. What is the issue? Include screenshots / videos if possible!
    I dont want the water to be at the position where the bottle hit something, I want it to hit the ground right below it. Example: A water bomb is thrown and it hits a wall. I dont want the water to be floating on the wall. I want it to be at the ground below it. I dont know how to do a raycast like this. What if the bottle is oriented? Will the ray’s direction be the Y axis of the bottle or the world’s Y axis. I want the ray to go down regardless the orientation of the bottle.

I dont know how to properly set a ray’s direction. Please explain in an easy manner. I am a very noob dev and cant understand the language of higher beings.

If you set the raycast from the world position of the bottle not the cframe position than you are able to get a straight raycast down to the ground for example:

pos1 = bottle.Position  -- 'bottle' would be the bottle instance
pos2 = pos1 -, -20, 0)  -- we are subtracting 20 of the y value of the position to get a position lower than the first point
local raycastResult = workspace:Raycast(pos1, pos2)  -- Send out raycast

I am going to test this. Thank you for the reply!

Sorry for asking but how do I get a parts world position? Is it the same as “Position”?

Yes it is “World position” is just another saying for the parts .position property
