[v3.0] GuiCollisionService - Gui collisions done right

jaipack17 · July 24, 2021, 4:14pm

Correct, as of now it does not support AnchorPoint. v1.17.0 will have these updates in it! I am working on these features currently, new updates will be released soon!

This as well!

you can use this for that

Amazing thanks! I ll be sure to credit you! If I end up using it

jaipack17 · July 24, 2021, 5:56pm

Great news!

Tomorrow, I will be posting the tutorial about making your first GUI Based 2 dimensional game on Roblox! And this module will be included in the tutorial, so you can check that out as well for some more use cases of the module!

Update v1.16.3

Updated how OnCollisionEnded event is fired. It will not fire unnecessarily when hitters are not in touch with colliders.

jaipack17 · August 4, 2021, 6:43am

Update v1.17.0!

Added “solid” property to :addCollider(), setting it to true makes it impossible for a hitter to go through a collider! Example:

new ‐ Made with Clipchamp

local GuiCollisionService = require(game.ReplicatedStorage.GuiCollisionService)

local group = GuiCollisionService.createCollisionGroup()
group:addHitter(guiInstanceHitter)
group:addCollider(guiInstanceCollider, true) -- To make it impossible for a hitter to go through the collider

Updated Source code

Updated Documentation

Special thanks to @RuizuKun_Dev without whom, this wouldn’t have been possible, after understanding the math, I was able to figure out how easy this was to implement!

I am working on a 2D RayCasting module to help you cast rays even when the rotation of the gui is not 0 for 2D projectiles. Stay tuned!

There are a few bugs to this, which I have been fixing, thanks!

Currently working on Tween Cancelling when the hitter collides with a Solid collider for some neat 2D physics! Will be out in v1.18

This is amazing, I will be using this asset to replicate collisions on the 2D version of my custom particle system

jaipack17 · August 7, 2021, 5:07am

Update v1.18

Tweens will now be cancelled if the hitter touches a solid collider!
Added tweens parameter to :addHitter(instance, tweens) function! which cancels those tweens if the hitter touches a solid collider! View Docs
Added :updateHitter(index, instance, tweens) function which updates already existing Hitters, their instance and their tweens! View Docs
Added :getHitterTweens(index) which returns all the existing tweens of the hitter that are being played or haven’t been played yet. View Docs
:addHitter() and :updateHitter() function now return the hitter that was added which can be used as follows:

local addedHitter = group:addHitter(script.Parent.Hitter, { tween, tween2 })

addedHitter.index -- index of the hitter 
addedHitter.instance -- the instance that was marked as the hitter, here: script.Parent.Hitter

If you have any questions regarding the update, be sure to ask me!

hboogy101 · August 7, 2021, 6:50am

Does this work with rotated GUIs?

jaipack17 · August 7, 2021, 7:13am

Unfortunately, this doesn’t always work with Rotated Guis, I am planning to implement that in the upcoming version, thanks!

jaipack17 · August 10, 2021, 9:45am

Update v1.19

Minor Bug fixes
Code cleanup
Added :updateCollider() function to update already existing collider’s instance and solid property. View Docs
:addCollider() and :updateCollider() functions now return the collider that has been added:

local collider = group:addCollider(someInstance, true)

print(collider) -- {index: number, instance: instance, solid: boolean}

I have also been playing around with Gui Collisions when the guis are rotated, next update will consist of gui collisions even if the guis are rotated.

as suggested by @hboogy101

I wish to make 2D game development on roblox 10x times easier for you guys!

SteadfastLatvietis · August 12, 2021, 8:18am

this is pretty great, good job! will have to use this to make my game’s GUI’s

jaipack17 · August 12, 2021, 2:58pm

Update v2.0

Added :setZIndexHierarchy(boolean). The function is used to determine if the hitter will collide with colliders that have different ZIndex values. Setting it to true, will make the hitter not detect collisions with colliders that have different ZIndex value than the hitter. Setting it to false, will make the hitter collide with colliders no matter what their ZIndexes are. By default this is set to false. View Docs
This feature can be used to create Slopes in 2D Games, slanting roads, caves, objects you can’t go through but can go behind and in front of them, by changing the hitter’s ZIndex. For example:

Update v2.01

Added .isInCore() function. This function is used to determine if a gui object is completely inside of the area of another gui. This function returns true if a gui is completely inside of another, else it returns false. If guiHitter’s size is smaller than that of guiCollider, the function returns false. View docs

Video Examples:

(ignore the “too” misspell)

This works with tweens as well!

Example Code:

local GuiCollisionService = require(game.ReplicatedStorage.GuiCollisionService)

print(GuiCollisionService.isInCore(someHitterInstance, someCollider)) -- prints true if hitter is completely inside the area of the collider, else false

Use Cases

This function can be used to create Rhythm game scoring mechanics. For example a “Perfect hit” or a “Miss”

Like that of fnf or robeats:

Minor update to .isInCore(). It now works for rotated hitters as well!

jaipack17 · August 21, 2021, 7:21am

Update v3.0

After a fairly long wait. The update you all have been waiting for is finally out! (sorry for the long wait)

This module now perfectly detects collisions for rotated Guis! How? Its fairly simple! With the concept of ray casting. Each point casts a ray on the x axis, if the ray intersects with any of the edges of the gui and if the point lies inside the gui object, both guis intersect! No matter what the rotation of the guis are!

Example Code for the video

local GuiCollisionService = require(game.ReplicatedStorage.GuiCollisionService)
local group = GuiCollisionService.createCollisionGroup()

--GuiCollisionService.

group:addCollider(script.Parent.Still, false)
group:addCollider(script.Parent.Still2, false)
group:addCollider(script.Parent.Still3, false)
group:addHitter(script.Parent.Move, {})

group:getHitter(1).CollidersTouched.Event:Connect(function(hits)
     group:getHitter(1).BackgroundColor3 = Color3.new(0.333333, 1, 0)
end)

group:getHitter(1).OnCollisionEnded.Event:Connect(function()
     group:getHitter(1).BackgroundColor3 = Color3.new(255,255,255)
end)

Currently this does not work with solid colliders as expected. But works perfectly otherwise! Will be added to solid colliders soon!

Hope this update helped a few! Alongside this, I am currently working on a 2D RayCast module for you all! Thanks!

Really good module! Keep up the good work! Hopefully, I’m gonna use this for future project!
