Using 2.5D (Isometric) projection to emulate Don't Look Down

[twofoursixeight]

Continuing the discussion from I don't know how to make my map like Don't Look Down:
Any ideas or contributions? Feel free to edit.

So a while ago, this post was made showcasing a 3D 2.5D art libary.

3D Art Library (Post here)

GKC 3D art is an art style with a lot of potential. It often uses extensive layering. I invite you to share 3D art here (made with Gimkit Creative, of course…)!

Basically, this can be thought of as a 2D side-scroller with a form of tilt added inwards to emulate the 3D effect. There have also been guides showing how to emulate jumping. I have linked a few guides below to help showcase this:

[1️⃣] - A Simple Jump System and the Collision Concept by kyro

Are you editing? Check if you are. Do not check if someone else has a check. Do not check for fun. I suggested a jump idea in the Gimkit discord when they announced the new gim designs since it’d be pretty useful. However, one problem, how would this work? Why this works: The Problem of Jumping in 2D Games: When making a 2D game, you basically have 3 options for perspective: top-down, side-on, and isometric (2.5D). Each has its own limitations, in most top-down games, like Gimkit, you can’t …

How to make a "jumping" system! (Difficulty: 3/10 ) [WIP]

Let’s say you built a bridge and there is a gap in the middle of it, and you want the players to be able to jump over it. Well, this tutorial will tell you how to make a “jumping” system and how to make it cost energy! poll Part 1 Start by making the place where the players have to jump over. I used water as the gap. Make sure you can’t walk through the gap or else players can just skip through it! [Screen Shot 2023-10-05 at 6.00.08 PM] Add 2 teleporters on each side of the place you …

How to simulate jumping in GKC | Difficulty: 2/10

So, I was looking through my Geometry Dash Help post, and I found a post by @EggNoodle . Here’s the post: [Screenshot 2023-10-23 9.45.21 AM] And I started working off of that, and I struck GOLD! My shot in the dark was a BULL’S EYE! Here’s how to make a jump button, and it’s fairly easy! What you’ll need 1 Game Overlay 3 Teleporters 2 Triggers Step 1: Go into the Game Overlay and make it a button, labeled “Jump”. Make it transmit on “Jump” when pressed. [Screenshot 2023-10-23 9.52.04 AM…

All of them have a problem though. We are dealing with an isometric view which may make the simulation of jumping unclear. However, emulating jumping is one thing to get this dealt with.

Next, we need to deal with making obstacles. How? Maybe make an insta-kill for the “holes” and then simulate jumping to bypass the insta-kill.

So you know the game, Marble Madness? Well, a 2.5D Don’t look down can be based off that game, and we can take inspiration from that game and use it as a baseline to expand on simulating DLD. Why Marble Madness? That is a 2.5D game like the 3D art libary, and Marble Madness can be though of as a 2.5D Don’t Look Down with a Z axis.

Here is a screenshot from the game.

You can see what isometric projection looks like in it’s glory. If you think about it, there are three axes.

X, Y, and Z.

We don’t need to use the Z axis for a reason. Why? Don’t Look Down is a 2D game, and 2.5D can use a Z axis, yet we don’t need the Z axis for 2D games. Therefore, this concept can be used to get ideas on a 2.5D Don’t Look Down. That is all I need to mention about how we can get DLD to work in a 2.5D space.

But wait, what is Isometric projection?

Isometric projection is a method of drawing in 2D that can be used to visualize in 3D. The three axes, X, Y, and Z appear in increments of 120 degrees. This is just the simple concept of isometric projection, but it can get a lot more complex than that.

Feel free to read an article on isometric projection:

Isometric projection

Remember Gimkit?

The 3D art libary uses isometric projection to reach this goal.

3D Art Library (Post here)

Wait: Where is the Z axis?

It does not exist. Why does it not exist?

Well, It’s not there. The X axis is facing to the right, and both Y and Z match. This means we have no clear indication of Z axis. The Z axis is non-existant because it clearly could not be displayed properly.

We can still accomplish this goal. All we need is some 3D layering, effort, and enough memory and effort.

Alternatives

If you want a simple 2D version, this guide sums it up. It’s really easy but doesn’t have any gravity or jump mechanics.

How To Make a Don't Look Down Game

I’ve seen so many people ask this since DLD was released so I decided to make a guide on how to make a fake Don’t Look Down while we wait for the update. It’s really rough because it uses walking physics instead of jumping physics, but it’s something. Also this is my first guide Start with a ground like this: [image] The teleporter on the left is in a group called “Left” and teleports to a group called “Right”. The teleporter on the right is the opposite. This way when the player reaches ei…

[The_7th_Dragon]

Mmm cool!! This is so interesting…

[TimeMechanic]

This pinged me for some reason idk. But I’m not remaking my nearly completed guide with these jump sims so mine will just be different. But these are good too.

[Blackfox45666]

i always thought dld was based on ¨getting over it¨ cuz it was a lot like that but interesting guide might lead to groundbreaking things

[TimeMechanic]

My friend said it’s Only Up but Gimkit.

[Blackfox45666]

yeah anyways lets try and not get off topic but still 2.5D dld might be possible just would require a lot of layering and complex mechanics

@TimeMechanic I think I may have accidentally overridded your edit

It’s okay I canceled I’ll do it again.

Haha you have given me too much power >:D

[the_chosen_one]

I love the 2.5D projection! I actually made my own system for Ds in top-down mode, it’s:
ᵹ₁: which is adding as depth axis with layering.
ᵹ₂: which is where there is a full downward blocks of space, not limited to the layers in top-down (but there is no jumping, only negative heights) technically 45° UCVA.
ᵹ₃: which is full 3d, entering the GDverse, with a UCVA (universal camera visual angle) of 45°.

Even though it’s not really needed, it’s helpful when trying to emulate other projects, not just platformers.

[InkyDarkBird]

Turning this into a research topic and sending to Devices because the majority of the guide is just theory and doesn’t show actual screenshots of parts of a working 2.5D Gimkit game.

[Quack_Quack]

Then- we could aim at making something like an 3D wireframe rendered cube like blackhole927 did, but add flatforming mechanics.

Some of this guide is helpful for other uses besides its main use.

[Quack_Quack]

Note: I’ve added the ‘theory’ tag because there isn’t much research yet for this topic.

[Turtle]

Removed theory tag since it wasn’t created with permission and is sort of redundant given that this is a research topic already. This topic was the only instance of the tag. If you think it should stay we’re talking about it in the tags and categories topic.

[Pineappleman]

this is a posible block to be put together to make a larger map

[Pineappleman]

after some refining

this is it with the barriers

[Pineappleman]

fun bigger platform

stairs are cool
