Unity Beginner Tutorial : Triggers

Рет қаралды 77,668

6 жыл бұрын

This is a beginners video tutorial for Unity in which I explain what colliders and triggers are and how to use them.
I demonstrate the use of triggers and C# by using a simple example for a third person character.
I am using Unity 2018 but you can use older version like Unity 2017 or Unity 5 as well.

wow, I watched this video 12 separate times confused why it wasn't registering... Finally heard you say the rigid body part and it worked perfectly

Alright, great you found it.

@@JayAnAm It might be worth adding a annotation to this video saying that at least one of the objects with a collider needs a rigid body. I had the same problem as ZatiCoh and had to do a little bit of research to find out why my triggers were not working. Great video with strong explanation and good example though!

Thank u so much!!! I wanted a pressure plate that when stepped on would load a scene. This video helped me understand triggers and i made code that when the player would step in the trigger zone it would load the next scene.

Great job; another gotcha is the OnTrigger is called only on the object level, so if your script is one parent above the collider, it won't get called, or below really. For tutorials you added it to the Collider object, which is great, but sometimes you have nesting involved and something to keep in mind.

Clear and simple tutorial. I have a doubt , what if i need to change the color of the character instead of that cube?

Great tutorial. Simple and to the point! I have a small question. Let's say I want only the player to activate the trigger. How should I go about it? Something with Tags? Thank you

@sqrddouble6003 4 жыл бұрын

I was wondering if you could make it’s so that the player changes colour instead of the platform despite the platform being the trigger and the player being the collider.

Hi, thx for the really great tutorial, I have a question, works perfect with my OVRplayer but when i throw a rigidbody grabbable cube onto it, it will trigger but not revert to old color on exit?

Nice going bro i would really love to see the melee combat script for a player What i mean is that when a player's certain animation lets say melee attack is performed and hits the enemy it damages the enemy and then dereases the enemys health(enemy and player both have health bar) and enemy can do so i am having trouble doing this kind of stuff and cant find a nice one online. Can you do it?

This will be a part of the Low POly Game kit I am developing, but will take some time till I am at this point. You can checkout my Unity UFPS videos, were I implemented a logic that is a bit similar to this.

lets say i have 1 game object with 2 triggers, and then something collides with one of that object's triggers how could i tell apart which trigger got collided with?

@ahmedlive 4 жыл бұрын

Do you know how to make it so it doesn't activate the trigger with parts like the floor? like if the floor has a collider, how do I make it so it can ignore only the floor?

@JayAnAm 4 жыл бұрын

You can check the layer based collision detection : docs.unity3d.com/Manual/LayerBasedCollision.html - or you just check in the OnTriggerEnter the Collider parameter and react if it is of a certain type (like has a special name of has a certain componant attached) only.
