launch player towards specific block

I don't know how to launch a player toward it but I can make it so you teleport there here is how.

first create a ranged item then fill all information. when this is done click green plus next to when bullet hits block and put execute command / "clear" at x: x y: y z: z where it says clear change it to tp @s. this block is found in world management tab. it should work but I have not tested yet

Hmm, you could take the coordonny of the projectile when you it a block then you compare it with the player coordonny and you creat velocity in X, Y and Y to launch the player in the right direction, let me see this on MCreator

Something like this? https://mcreator.net/forum/78422/very-simple-webslinger-tutorial

Hmm. You might be able to fiddle around with this command thought: /tp @p ^ ^ ^1

It teleports the player 1 block in the direction they're looking. So then you could try making it so that when the bullet is shot, it will automatically spawn a new entity (Invisible, no AI, no movement entity) and that entity points in a specific direction that the player was looking at, then it continuously runs the tp @p ^ ^ ^1 then tp @p ^ ^ ^2 and so on until when the bullet you threw hits the ground, it kills that entity and stops the player's movement. This one might take a while to do though, so maybe there's 3 variables: Where the bullet lands x, y and z. It compares this to the player that threw the bullet. Then it kinda slowly teleports the player there little by little. Let's say the player's coordinates were 0 0 0. And the bullet landed at 10 20 -30. First, it calculates the distance the X value traveled by. 10-0=10. Next the difference in Y. 20-0=20. And Z. -30-0=-30. Next, let's say you want to teleport there in a series of 10 teleports. It'll divide all three values by 10 to get 1, 2, -3. Each time the player will teleport 1X, 2Y and -3Z. That way, after 10 teleports the player will be at 10 20 -30. Sorry if my explaining was bad.
