I'm currently making a 2D game as a beginner and I wanted to add joystick controls to my game. I made everything like in the youtube video of Brackeys, but I always get this error:

I am working on a dialogue and questing system for a 2d game I am working on. I am attempting to have multiple NPCs that will give different quests with different dialogue that is unique to each quest. I attempt to trigger my dialogue whenever a player presses the E key. Currently my game displays the dialogue whenever the player becomes in contact with the NPCs collider. The dialogue also begins with the second sentence of the dialogue array. Additionally, once the player has interacted with multiple npcs, the dialogue for all npc becomes the dialogue of the last npc that was interacted with.

Here is my code:

I am working on a game and I am implementing a quest system. I am trying to assign the quest script to the QuestGiver NPC that I will have but I am receiving an error. My error is Cannot convert UnityEngine.Components to Quest.

This is my code:

I'm new at Unity and C#. I started this 2D game few weeks ago.

So basically what I want to do is when the player is hit by "FrostBullet", it should deal the damage and slow that player over time. In my script the player is hit by FrostBullet, it deals the damage and the slow is constant, not over time. I want it to be like, when the player is hit by FrostBullet, the player should be slowed for 2 sec and than his movement speed is back to normal.

So this is how my code look like:

I have successfully created my first game in Unity which let's user move through surface. It worked fine. However, I now also want to be able to move player with voice input. They player jumps when it hears the word jump but for example to move the player forward when it hears go, I simply used transform.Translate(2, 0, 0). This moves player in forward direction but it doesn't care how the the surface is, for e.g. it moves through objects or moves straight even if there is a slope ahead. Movement with keyboard doesn't have any of this problem.

This is my code:
