Previous template Next. I have a box collision in the actor BP that you can press to move to the next level. The only problem is that even though the 3dwidget is hidden the box collision is still active allowing the player to overlap that and move to the next level without completing the task.
Is there any way to disable the box collision while the 3dWidget is hidden and enabled when it is not? Tags: None. Yes just set collision of the box to none when you need it. Just get collision and set to none or overlap all or whatever you need. Comment Post Cancel. I don't know what your set up is, so I dunno if we not understanding exactly what you want to do.
But basically when you need it you would enable collision on your collision box and when you don't need it you would disable it. Kinda like so: just using some custom events in my example, but basically when you hide your 3D widget you would disable the collision and when you make it not hidden you would enable it again. Thats perfect thank you. EpicForum Style. Yes No. OK Cancel.The system we have can seem a little complex at first, but it is very powerful and consistent, so I wanted to give a little background on how we arrived at it.
The first thing to know is that when you say something should collide, you have to choose whether you can penetrate it or not. Or does the query decide what types of object it is looking for? In different scenarios they both make sense, so UE4 supports both! A brick wall is set up to block both, a shrub blocks visibility but not weapons, and bulletproof glass blocks weapons but not visibility.
When you do this kind of query you specify a single Trace Channel. If I changed this around so the game code had to know what types of object to query for, our game could need a huge number of different types to handle all these situations!
When you do this kind of query, you can specify multiple Object Channels. Things get a bit more complicated when you want to handle collisions between moving objects, because there can be so many combinations. When two objects intersect, we look at how they respond to each other, and take the least blocking interaction, like so:.
Now the player moves forward. First he will overlap the shrub. The Player is of type Pawn, and the Shrub wants to Overlap that. Checking the chart, the final result is Overlap! Similarly the Brick Wall and Player both want to Block each other, so the player walks through the Shrub generating an Overlap event and is stopped by the wall generating a Hit event. Even though this system gives a lot of control over what objects in your level will collide with, in practice most objects fall into common configurations.
When you select an object in the level, you will see a simple dropdown, allowing you to select a Preset:. UE4 has several of these built in e. Complex Collision refers to using the actual rendering geometry for collision. This is most useful for things like weapon traces, where you want to be able to shoot exactly what you see. When you perform a collision query, you tell UE4 what kind of geometry you want to collide with. In the editor there is a handy View Mode that lets you see the world as a player will collide with it:.
So that is the whole, heady world of collision filtering in UE4! I hope it was helpful to understand some of the problems we are trying to solve and how to make use of it for your own game.

I'm making a 2D platformer, and I want the main character not to continuesly get hit by moving enemies.
So I was thinking too temporarily disable collisions so that the enemies continue walking without hitting the main character. Tags: None. Use the node "set collision enable" you have three options, one is not collision. Comment Post Cancel.
Particles sometimes ignore collision
Hello there! Just right click in the graph and type collision, it should be visible in the list then. Allows you to choose between no collision, no physics collision, and collision enabled. Last edited by DotCam ;PM. Trello Roadmap. Hello, first of all, thank you for the replies! I'm looking into " set collision enabled" and "set actor enable collision". What is the best way to make my blueprint like this work: I just want, that when the actor takes "any" damage, the actor's collision is disabled for seconds.
Basically making him invulnerable for that short period of time. I've tried and failed, but maybe I'm looking at the wrong way to do it.
Set Disable Collision
Solution found Hello, for everyone who helped me, my gratitude! I solved the problem. For anyone in the same situation: The disable collision werks perfectly for the enemy actor. As it is a matinee moving him from position to position, he wil continue moving, but only hurt the main character once, without being an obstacle.
Does anyone know if you can disable collision of the capsule for certain animations?
EpicForum Style. Yes No. OK Cancel.In Unreal Engine 4, you have access to simple and complex collision shapes. Simple Collision are primitives like boxes, spheres, capsules, and convex hulls.
Complex Collision is the trimesh of the given object. By default, Unreal Engine 4 creates both simple and complex shapes inside Physx, then, based on what the user wants complex query vs simple querywe will use the corresponding shape. This will cause simple collision requests to use simple collision, and complex requests to use complex collision; the "default" behavior.
This means that if a complex query is requested, the engine will still query against simple shapes; basically ignoring the trimesh. This helps save memory since we don't need to bake the trimesh and can improve performance if the collision geometry is simpler. This means that if a simple query is requested, the engine will query against complex shapes; basically ignoring the simple collision.
This allows us to use the trimesh for the physics simulation collision. Note that if you are using UseComplexAsSimple you cannot simulate the object, but you can use it to collide with other simulated simple objects. For example: in the image below the chair on the left has simple collision, and when the Pawn above it falls onto it, it will slide off the large angled surface that covers the seat.
However the chair on the right is using UseCompleAsSimpleand when the Pawn above it falls, it will land on the seat of the chair and stay there.
We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime. Simple Vs Complex Collision. Unreal Engine 4. On this page. Setting Description Default This will cause simple collision requests to use simple collision, and complex requests to use complex collision; the "default" behavior.
UseSimpleAsComplex This means that if a complex query is requested, the engine will still query against simple shapes; basically ignoring the trimesh. UseComplexAsSimple This means that if a simple query is requested, the engine will query against complex shapes; basically ignoring the simple collision. Select Skin. Welcome to the new Unreal Engine 4 Documentation site! We'll be sure to let you know when the new system is up and running. Post Feedback.Simulating Physics and Collision Presets.
In UE4, you can have Static Meshes do many things, such as change its texture or material during gameplay, or move throughout your level using a Matinee. Chances are, whatever you have your Static Mesh do in your level, you do not want to have the player able to walk or shoot through the mesh.
That is where setting up collision on your Static Mesh is useful. You may already have a level and Static Meshes of your own to work with. If you do, you can skip this step. If not, launch UE4 and create a new project. Name your project and choose a location for your project to be stored. In this example, we are going to use the Blueprint First Person Template.
You do not have to work out of this template, but the ability to fire projectiles that is already implemented in this template will be used to demonstrate a point later, so using this template may help you follow along. Also make sure that you enable Starter Content.
If you do not, you will not have the assets that we will be working with later on in this "How-to" which may make it difficult to follow along. Once you have the project open, if you enabled the Starter Contentyou should have a folder in your Content Browser that is labeled Starter Content. Within that folder should be another folder labeled Props. Once the editor is opened up, you should see something similar to what is shown below:.
By default, there is no collision set on this mesh.
Without collision, the player would be able to walk through the mesh and if the mesh simulates physics, the mesh would simply fall through the world as soon as play began.
You can test this by placing this mesh into your level before setting up collision and playing. Note that your player can walk right through the solid mesh. Also, if you wanted the door to blow away when you shoot it, or start off in the sky and fall to the ground, you would need to set Simulate Physics to true from the Details panel, which you cannot do by default if the Static Mesh does not have collision. These effects are undesirable in most cases, so we will go ahead and set up collision for this mesh.
At the top of the editor, there is a Collision drop down menu. If you click on it, you will see the options you need in order to add collision to your mesh. In this case, our mesh is a rather simple shape. This will make things easy when trying to set up collision for our mesh.
The top three options in the Collision menu will surround our mesh with a simple shape that will be used as the bounds of what can and cannot be blocked or overlapped with our mesh. Below are examples of the mesh with these simple shape collision meshes. After setting the collision, if you still cannot see the outline around your mesh, make sure that the collision button in the toolbar, is highlighted. Also note that if you already have simplified collision on a mesh and you add another simplified collision to the mesh, the new collision will not replace the other collision, but add to it.
If you add all three of the simplified collisions from above without first removing any of the collisions, you might have something that looks like this. To solve this, you can either select one of the collisions and press the delete key or select Delete Selected Collision from the Collision drop down menu to remove them one by one, or, in the Collision menu, select Remove Collision to remove all collision on the mesh.
A pop-up will appear asking if you are sure that you want to remove all the collision meshes. Clicking Yes will remove collision from your Static Mesh. After applying collision to the mesh, notice that the collision has a translation widget. After you have set collision, you can translate, rotate, and scale the collision meshes just like you would with any other object within UE4.
If you have a mesh that can easily fit into a capsule or box, or have a mesh where having precise collision does not matter, using the simple collision we set up in the last section will work fine. However, you may have a mesh that is a more complex shape yet still needs to have precise collision. In this section, we will go over how to set that up.
Double-click on the thumbnail to open it up in the Static Mesh Editor.With the new collision filters and joints etc. It serves no function at all.
If a player want to set arms to collide, let him do it. If it causes glitching, so what? He choose to set the collision therefore he choose the consequences. I support. It can get really annoying the the limbs can clip through parts sometimes. Having collidable limbs sounds cool, but a good idea would be to simulate this and try out for yourself.
For all Humanoid limbs.
Agreed, same with torso. Let the developer decide how the collision should be handled. I still have to resort to collision hacks for npcs since collision filters are server only. Explain how this would affect any current games? Obbies tend to rely on that behavior. I mean ROBLOX being concerned in backwards compatibility has always been a thing so I figured this should be in consideration with this request too. Edit: Wait, did I misread it?
Afaik arms never collided with parts so like in obbies it would let you turn your character on thin platforms. We should be able to change CanCollide on humanoids - this is what the OP means. Reminder that this is still an issue for anyone trying to do anything remotely complicated with Humanoids. Completely unnecessary and is such a pain to work around. Humanoids really need a rework or something. Remove Humanoids forced collision on Parts it's obsolete Platform Feedback.
