How would I go about making Interactive plants/grass

Help and Feedback Scripting Support
#1

Hey! I have been working on a game and I want to add a feature that I am struggling to figure out. I would like to make an interactive plant/grass system like The Wild West game on Roblox. Basically when the player touches the plant/grass it will tween in the direction the player is looking.

I have no idea how to go about this system and I really need help. I am not that good at scripting and i know very little about look vectors and CFrames.

I have tried to look through other topics about this, but I have no idea where to start?

Try experimenting with Touched and TouchEnded. Not 100% recommended but it might work.

If I understood you right, you want to make a Plant that whenever you approach him / presses ‘E’ or something, it’d open a dialogue with him?

#4

no not at all, I want it to move the plant when you walk into it like The Wild West

#5

Oh, my bad. Never played The Wild West,

I believe you can move the plant model to a desired position when either a player’s distance from it is really close[meaning he’s walking into it], and if he actually reached distance 0, you could make the plant move aside or something.

A few articals on moving models:

thanks, I will give that a try, only one thing I want to make it so that the plant moves in the direction the player is moving

here is an example, the plant tweens in the direction the player is walking

I think you can use CFrame.lookAt and look at the character’s torso.

thanks! that’s a good idea, can you show me a code for that because I have tried that but I don’t think I did the code right. I tried basing it off this other persons topic but i could not get it to work

this is what I scripted but it does not work, Do you know why?

local grass = script.Parent.Parent.Grass
local ts = game:GetService(“TweenService”)

grass.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild(“Humanoid”) then

	local hum = hit.Parent:FindFirstChild("Humanoid")
	local movedir = hum.MoveDirection.Unit
	print(movedir.X, movedir.Z)
	local facevector = grass.CFrame * CFrame.Angles(math.rad(movedir.X), math.rad(0), math.rad(movedir.Z))

	local tween = ts:Create(grass, TweenInfo(.5), {CFrame = grass.CFrame * CFrame.Angles(math.rad(movedir.X), math.rad(0), math.rad(movedir.Y))})

	tween:Play()

end

end)

it says I ERROR: attempted to call a table value

#17

What line of the script? You need to give all the info about the error possible.

#18

ooh sorry ya line it is 15 i cant figure out why

#19

so I was thinking and I decided to put all the plants in a folder, so I rewrote the script to make it work for all plants. The issue is that that doesn’t even work I set it to move the primary part but it won’t work. Btw I fixed the line 15 issue I had to put 0.5 in the TweenInfo spot

#20

here is the new script

local grassfolder = workspace.Grass
local ts = game:GetService(“TweenService”)

while wait(.1) do
for i, grass in pairs(grassfolder:GetChildren()) do

	grass.HitBox.Touched:Connect(function(hit)
		if hit.Parent:FindFirstChild("Humanoid") then
			
			local hum = hit.Parent:FindFirstChild("Humanoid")
			local movedir = hum.MoveDirection.Unit
			print(movedir.X, movedir.Z)
			local facevector = grass.PrimaryPart.CFrame * CFrame.Angles(math.rad(movedir.X), math.rad(0), math.rad(movedir.Z))

			local tween = ts:Create(grass.PrimaryPart, TweenInfo(.5), {CFrame = grass.PrimaryPart.CFrame * CFrame.Angles(math.rad(movedir.X), math.rad(0), math.rad(movedir.Y))})
			
			tween:Play()
			
		end
	end)
end

end
