Eldiron: A Next-Generation Classical RPG Creator

Vision

Eldiron aims to revolutionize the creation and experience of classical role-playing games (RPGs) by blending the nostalgic charm of timeless RPGs with the cutting-edge capabilities of modern technology. My mission is to empower creators with an intuitive, yet profoundly flexible platform, while enchanting players with immersive, dynamic worlds that breathe life into every adventure.

Core Features:

Grid based Visual Coding System

Code character and game behavior in a grid based visual node system. Combining the power and speed of real code with the ease of use and visual debugging of a true node system.

Create worlds using tiles or model with nodes.

Either draw in pixel-perfect precision using 2D tilemaps or model worlds procedurally with an integrated powerful node system.

Both ways allow you to create world regions in both 2D and 3D. Eldiron ships with an integrated Ultima like tilemap to get you started.

Visual effects made easy

You can easily add visual effects to your world. Imagine placing light sources, animating gates or adding mirror effects. To name just a few.

.

Time based behavior

Everyting in Eldiron is driven by a 24 hour timeline. Define time based character behavior, open gates or passages at given times or modify the world by estinguishing light sources during the day.

Worls created by Eldiron are not static but dynamic in every possible way.

Render your worlds the way you like it

Eldiron provides a vast array of rendering options, either classical 2D tiles or fan favourite first person or top down perspectives like isometric top down views or even tilted perspectives like in Ultima 6 / 7.

Define rendering options per region to be able to seamlessly switch between different views.

... and much more like the upcoming multi-player / server support.

error: could not compile `core_embed_binaries` due to previous error

What was I expecting?

That I can compile and run the Creator Module

What I did exactly:

• cloned/pulled the repo from Github on a MacBook pro running the Beta of macOS Ventura, rust installed
• tried to start the process via console "cargo run --bin creator"

Collaborators Needed

I think what I need for a v1 are some collaborators who can help with the design of the character system and help to flesh out the demo. I am mostly a developer and while I played the Ultima and similar games a lot, I am not an expert in all of the character class design systems on the market. I just want to make sure to support all possible use cases for weapons, gear, spells, crafting character progression and so on, which is a lot of stuff.

Would be great if some of you would collaborate on this a bit, it would make a v1 much easier todo on my side as I do not need to worry about design choices all the time.

Will there be detailed help documentation and tutorials?

Not at all sure how to get started with it

Release v0.7.5 is incompatible with Ubuntu 20.04

Hello!

I wanted to try your project out of curiosity (I bumped into your project looking at Rust game engines).

You may be already be aware of this incompatibility:

$ /usr/bin/creator_main

No LSB modules are available.

For info, I did not quite understand what Eldiron is by reading the README. Is it a no-code tool? Will I program my game in Rust? Etc. You may be interested in that feedback to refine the README just a tad :)

Hi,

ran into another problem (if I'm bothering you with there minor issues, just let me know :-) )
