2D-Platformer: Progress Log #5

The Floor Is Lava

The aim is to to make moving platforms the player can jump on.

So I want the platforms to have their own collision detection which means more raycasts. However the controller2d script has pretty much everything the platform script needs so I’m going to create a new script of which they both can pull from to avoid repeating script and make for a much more accessible code. To do this I move all the script from the controller2d to raycastcontroller and make the floats and methods public. Im also hiding the below attributes from the inspector because its in the below calculateraycast

Okay I forgot to screenshot the error but it was

CS0122 RaycastController.raycastOrigins is inaccessible because of its security level

 And it was because I forgot to make it (along with boxcollider) public

Im testing the following code (moving a platform vertically)

With this

I tested increased the velocity to test if it fell apart at high speeds however is dealt with it well.

The character is not moving with the horizontally moving platforms so I have implemented the following

2D-Platformer: Progress Log #4

Criss Cross will make you

The rays keep building gravity when the player is on a platform which is an issue when I’m writing script to jump. Sooooo I’ve implemented the following (after an hour long google)

After putting this in place gravity in general does not exist. To be addressed…

I have since decided to remove this piece of script and if it causes issues down the line I will address it then.

I currently have values assigned to jumpVelocity and gravity which is rather non descript and pretty much for testing purposes so Im going to take away their value and instead create a specific jumpheight and timetoJumpApex which are far more inutuitive and effect the former variables anyway. This involves some equations (which I may or may not have added to prove I still remembered some physics)

Know Variables: jumpHeight , timetoJumpApex

Solve: gravity , jumpVelocity

Finding Gravity

deltaMovement = velocityInitial * time + acceleration *time(2) / 2

Replacing those values with my variables ( Initial velocity is = 0 so it can be removed from the equation) 

jumpHeight = gravity *timeToJumpApex(2) / 2

2 * jumpHeight = gravity * timeToJumpApex(2)

2* jumpHeight / gravity = timeToJumpApex(2)

Gravity / 2* jumpHeight = 1 / timeToJumpApex(2)

Gravity = 2 * jumpHeight / timeToJumpApex(2)

Finding jumpVelocity

velocityFinal = velocityInitial + acceleration * time

jumpVelocity = gravity * timeToJumpApex

Below is the implemented code + debugging method

Running into poles

Collision detection typically refers to the computational problem of detecting the intersection of two or more objects aka player + obstacle. The idea is that the collision code modifies the velocity so the player doesn’t go through anything

If player is moving down the rays need to start from the bottom left corner and if player is moving up they need to start at the top left corner.

 Errors that occurred:

[brees-portfolio-of-weird-stuff]

2D-Platformer: Progress Log #2

The first error is always the most stupid

Skin width is a thing. Use it

Skin width is when the rays are not being fired from the edge of the players bounds, rather slightly within the parameter so when the player is on the ground the rays can still be fired. If this isn’t there the rays can’t be fired and the player can’t jump. I did not know this… thank you google.

The following script was implemented

2D-Platformer : Progress Log #1

Here we go again

You know how you’ve spent two terms in python and actually just started understanding the code, wouldn’t it be an great idea to continue in this program to further your understanding and confidently develop an new project… NAH lets go back to your worst enemy… UNITY (specifically C#)

After binge watching a total of 10 different series of unity tutorials here is how I plan on writing my script (In somewhat simplified terms for my own sake) to build a 2d platformer.

I’ll be using two scripts

Player

Responsible for receiving input (Takes the information for example the velocity vector and sends it to the controller script)

Controller

Actually moves the player and sets constraints to the collisions by sending out horizontal and vertical rays.

I have chosen to use ray-cast controlling over rigid body as from what I have learnt it handles slopes a lot better which allows for more diversity in the games environment

Text - Based RPG: Project Log #1

And they’re off!

I want to start by saying as bad as this may sound, Its really nice not being the newbie. This is partially refering to the fact we have people in the class who have never coded before and partially because the course is similar to last year and despite everyone's constant whining I actually really like Python.

We were told what we were creating and RPG but heres the catch its Text-Based now while I refrain myself from going on a rant about how of course they take away the one thing that gives me an upper hand in this course I’d like to place the reasoning

 “Its to strip it down to the basics so its easier to understand” 

I understand the intention and for most this will probably work but I genuinely think this is going to slow me down significantly. I work in a way where when I can immediately see whats wrong or what a game is doing I can understand what needs to be done from there. That being said at least its only year 11 and its all about challenge. 

Next Log will be actual brainstorming

Text-Based RPG: Project Log #2

First of all I have never in my life played a text-based RPG. Im really not a role player, however I’ve played a total of two RPG games Pokemon and Avengers assemble and You can bet that I’m basing all my knowledge off of them.

So Ideally I want a basic game of escape a prison of some form

run into enemies (Like the way a character would run into a trainer in pokemon)

find weapons and health boosts 

and defeat a boss to get out 

I’d like to be able to choose between players but im not entirely sure how ambitious that will be 

Note: Luca is asking me for a lot of help because he doesn’t like talking to teachers, although this is mildly inconvenient as im already pretty slow, I’m having to explain concepts and functions out loud which is surprisingly helping me understand them in a coherent manner which is good.

Text-Based RPG: Project Log #3

As I have written these on a document in word to then post in a convenient order future Bree managed to find my original battler Logic and Ideas document so this is that, my apologies for any continuity errors this was quite literally the first thing I did.

Im also going to use the incredibly power of foresight to try to explain what I was trying to do.

Battle logic

Player – fire

Moves : Flame Ball

               Fire Wip

Villan1 – fire

Moves: FVP1

               FVP2

Villan2 – water

Moves: WVP1

               WVP2

Villan3 – earth

Moves: EVP1

               EVP2

I believe I originally wanted for there to be moves that were more effective then others depending on the type of enemy, similar to Pokemon in the sense of water beats fire etc This didn’t manifest itself however due to my underestimation of how long some of the coding took. 

Player Health: 100

Move options:                  

-Strong = 40-50

-Basic = 20-30

-Terrible = 0-10

 This is the logic behind it statistics wise

  Walk to trigger points and trigger enemy functions (separate files)

Player walks to Villan1 trigger

If player types “flame ball”  

               Villan1 loses 20-30 health

If player types “fire wip”

               Villan1 loses 30-50 health

Villan1 plays

If Villan1 plays “FVP1”

               Player loses 20-30 health

If Villan1 plays “FVP2”

               Player loses 10-20 health

If Villan1 loses 100 health Player continues to walk

 An example of how the battle logic was going to work which is still accurate baring the multiple moves.

Lux and Marco are kidnapped by the well-meaning asylum escapee Valentine. They must fight her minions to defeat her to escape to prison before they too are controlled

Python Log: 4. Progress Blog #1

The first IT lesson we ever had Our teacher made it very clear that computers do not hate. I feel I have unintentionally proved him wrong.

X-ray saves the day V.3

Technically its the first version however there are previous versions that are all completely broken that I've kept for archives sake. So far the script has only had two unexplainable issues, one of which may be an issue with what Python can run (Hopefully it is possibly fixed) and the other being sound which just does not play. At all... No matter what file type. I'm hoping its a banner type situation and if left the problem will spontaneously appear. This being said this version has successfully removed the useless jumping function and the camera view has been successfully constrained (however I need to go back and even it out) But it works!

Issues

- Animations

- Sound effects/Score

Changes

- Removed Jumping function

- Up and down Camera constraints

[brees-portfolio-of-weird-stuff]

Python Log: 3. Goals

Game Play

X-Ray (the player) is to shoot the enemies using their x-ray vision. This will cause the point meter to increase and then after a certain period of time the Boss will spawn and must be defeated.

Functions

-Walking animations on both enemies and player

-Shooting ability

-Boss spawning

-Point system

-Constrained camera view

-Scrolling enemies

-Point system

Python Log: 2. Original Idea and Concept

Unlike Simone I am yet to think of a witty title for theses logs.

My original idea for my game is to base it off a web series I am currently a huge fan of entitled “X-ray & Vav” a series about two amateur super heroes. Using the shows thowback to older kids tv shows I decided that creating a pixel art game not dissimilar to that of Space invaders or other simple arcade games. I will be manipulating Squirrel vs Squirrel to do so.

Python Log: 1. Challenges

Im only writing one post for the Challenges because frankly there isn't much to write and I'd prefer to spend more time on my game.

Essentially I finished most of the challenges with no issues. The final three challenges proved to be significantly harder and took a substantially longer time to finish (and Im pretty sure one of them are broken) But never the less I have a little more of an understanding towards the language which will come in handy while developing my game.
