games_oop_javafx | project demonstrates how to use Java Fx | Game Engine library

I am learning to program a game engine which is why I followed a tutorial, with that tutorial I have gotten this far and even though my code is identical to theirs (theirs did work in the videos) its not working the way it is meant to. The triangle stays black no matter what. There is not any errors.

Main Program Script:

I'm currently attempting to create a first-person space flight camera.

First, allow me to define what I mean by that.

Notice that I am currently using Row-Major matrices in my math library (meaning, the basis vectors in my 4x4 matrices are laid out in rows, and the affine translation part is in the fourth row). Hopefully this helps clarify the order in which I multiply my matrices.

What I have so Far

So far, I have successfully implemented a simple first-person camera view. The code for this is as follows:

I'm new to Godot coming fresh from unity and I cant figure out how to duplicate an object/node. I've tried the duplicate function to no effect. My most recent attempts try to create child nodes with the same property as the parent. I cant seem to get anywhere, help would be appreciated. Here is my code that tries to create a child node:

When I say "Entity" below, I'm not specifically referring to anything relating to the ECS pattern, I just mean a general game entity.

I'm trying my hand at game development in C, after having done previous game dev in TypeScript. I'm looking for a C idiomatic way to reuse a pattern with which I'm familiar: each tick, the game iterates through a list of entities, telling each one to update itself, then draw itself. Each entity knows how to update itself, but requires information about the game as a whole to make this update.

helloI'm making an object in Unity that gives players random weapons when they hover over it, but it always gives me this warning and doesn't create it.

I am trying to learn Godot by making a simple 2D shooter, but am running into a problem. I do not know how to detect if an enemy has been shot by a bullet. My bullets are Area2D nodes with a Sprite, and CollisionShape2D node attached. My enemies are KinematicBody2D nodes with a Sprite, and CollisionShape2D node attached. The enemy also has a timer attached, but that is not important.

Here is the enemy code:

I used to handle a group of sprites by push them into an array or sprite group which is build-in class in the Phaser. But I am seeking another simple way could get or remove all sprites in an scene. Does anyone have any idea to resolve this? Thanks a lot!

I'm trying to create a scoreboard using phaser3. It creates the board when I do the following in create function:

I Am New To Ursana Engine And I Don't Know It Properly. But I Can Make Games In It. But The Problem Is That My Game Doesn't Have Any . So My Game Looks Dead.

Is There Any Way To Make My Game Look Good Using In Ursana Engine?
