Feed me: more

Hi all, a quick post regarding my 1 month project for this round. No major development has been done this week except movement and camera controls. This, due in part for a coding exam for a job. So, for this post, I'll talk about some of the code and parts of Unity I'll be using instead of giving anything fun away.

For those who've never used it, Nav Mesh is Unity's way of dealing with AI path finding. It also makes moving a character in a way similar to Action RPGs like Diablo, Grim Dawn, and Torchlight. On another project I'm writing code for, I've found one issue with this system; all entities have a turning circle the size of a mini-golf course. Are there ways to work around it? Not that I have seen so far. Further experimentation will be required.
Luckily, the code to make a character move isn't too difficult for anyone to get their hands on. All you need is the mouse position, a Raycast, the hit co-ordinate, and the Unity.AI library. Easy!

It should look something like this:

if(Input.GetMouseButton(0))
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit))
            {
                _navi.SetDestination(hit.point);
            }
        }

This is called on the Update function.
So _navi is a reference to the NavMeshAgent that's on the player object. So when the left mouse button (LMB for short) is pressed down, a ray is cast from the cursor's position. When it hits anything, it sets the destination for the agent to move. From there, Unity handles the rest by calculating the distance and along with rotating the player object towards the point in a curve.

Next week, I hoep to bring you the game play in a video form (I hope).

It's been a while...

It's been about a month or so since I've updated here. No, I'm not dead. Currently, I've been assigning my personal resources to build a new game, and thus have not been building any one month builds. Progress with this next project is coming along quite well... Minus some issues here and there. So let's talk about "Project Mech"shall we? Project Mech is an extension from a prior prototype that I've built which was designed around the hacking mini-game from Nier:Automata. Inside this game, you play in a mech shooting up aliens that are hell bent on destroying you. Yes, small story premise, but the story of this game is supposed to be simple and corny so I can experiment with game-play instead. Ideally, I'd like to experiment more with video game narrative, though that is a different long form project. This project will NOT support building a controller, though I'd like to implement that some other time. I'll add some screenshots later...

Puzzzling Motion - The next 1 month build intoduction

Image
How do you design a puzzle game? What kind of puzzles do you put in a puzzle game? Is Physics involved? Complicated mathematics? or the ability to think outside the box in such a way that you are playing Antechamber? Or maybe you disguise your puzzles by utilising the world design like in Mirror's Edge and Portal games? hehe... Oh gods why (Antechamber) So where do you begin? I'm going to take this one month project to build a puzzle game based on motion. Let's start with everyone's favourite, baseline goals: Players must be able to move around to get to an objective The puzzles must be based on movement, pressing a button, flipping a switch, and then moving to the next puzzle  There must be materialistically, one level As always, we have our bonus round: up to 5 levels Parkour based movement An "open" area for testing out motions to better grasp motion mechanics. Now, where are where are we at the start? The first person characte...

Bits and glitches: Rooms, exploration and command

So this week, I've built some new rooms and added codes for going about exploration and combat. After a bit of tinkering, I've got it nailed down to key words for certain actions. Example: Go north to go north. Initially, it was flawed. I would look at the string as a whole, rather then looking for keywords It looked something list this: if stageAction == f"Go North" :         print( "do action" ) what it now looks like is something like this: if f"go" in stageAction or f"Go" in stageAction:        if "north in stageAction or f"North" in stageAction:                  print("do action") This allows me to make better actions for movement and combat. Combat is kind of in the game right now with an "Attack" action. Next week, more rooms and I'll show a snippet of the game as it runs.
