melikeycode / qtgameengine Goto Github PK

We need a markdown page (something like projectStructure.md) that documents every file/folder starting from the QtGameEngine folder.

Note: Some of this has already been documented in the diagrams, move it to the markdown page.

Use can use emscripten to run portable C++ code in a web browser. Basically, you feed emscripten your C/C++ and it will spit out javascript.

We should create a few example Qt projects that use QGE. Each of these projects should have all files they need except the qge folder (client needs to copy/paste the qge folder inside each of these projects to successfully run them - this is to prevent distributing multiple copies of the qge folder).

Benefits of having example projects:

• clients can quickly see and play with example projects that are already using QGE
• clients can use one of the examples as a starting point for their own game
• one or two of the examples can be used to create a video and/or text tutorial from

Here is a brief description of some example projects we can create:

1. blank map - Just a Game, Map, and MapGrid.
2. moving entity - add a moving entity to example 1.
3. multiple maps - add multiple maps to example 2.
4. enemies - add some body thrusting enemies and make them randomly drop items.
5. shop - add an entity that sells stuff (to demonstrate a gui).
6. extending - example showing how to create a custom item, projectile, controller, etc. Point is, it needs to show client how to extend the game engine with their own components instead of just using prebuilt components

This would help with debugging abilities that depend on entities entering the field of view of other entities.

Linear page structure.

First there should be a title:

Abdullah Aghazadah's
Qt Game Engine

Then the logo.

Then, an About section which states about (written in C++ ontop of the Qt framework, fun, easy, well written/documented, easy to extend)

Then a "Demo" section with link and pic to demo video.

Then a how to use in project section
-this section will state the two steps to using and will link to a more detailed page where they can learn about more flexable ways of using the game engine

Basic example (just a blank map)

Where to go from here

• watch youtube tutorials (link to them)
• try text tutorials
• play with examples while reading docs for classes you use
• if you are interested in contributing, read contribution guidelines
• contribution guidelines will have
  • familizrize yourself with game engine first (by watching youtube tutorials/text tuts/and doing examples)
  • read file/folder orginization
  • read conventions
  • will state how core team will be small and people with high quality contribs will get invite

We should create an example project (example5) that places a body thrusting enemy for the player.

We need to add a small ("teaser") footage of the game engine to the very beginning of the clip. This should fade into the video of me talking.

When you an entity moves from one map to another, and there is a size difference between the adjacent sides of the two maps, where should the entity move to in the new map?

Consider the adjacent edges of two adjacent maps. One map is way bigger than the other. Here is how we should decide where the entity lands in the new map. If the entity is 50% along current map's edge, it should be 50% along new map's edge. If the entity is 25% along current map's edge, it should be 25% along new map's edge, etc. This makes sense.

We need to keep track of people/organizations that we "borrow" ;) resources from. We should create a documentation page dedicated to this, called credits.

People to give credit to so far:
-Derek & Brandon Fiechter for bg music of test game
-open game art for art/sound

implementation steps

• place some items on the ground
• make sure player has item picker upper controller
• create inventory user

done :)

Summary
error: 'auto' return without trailing return type; deduced return types are a C++ 14 extension.

The error comes from STLWrappers.h where 'auto' type specifier is used.

OS / Softwares / Compilers

• Windows 10
• QT v5.9.0
• MinGW 5.3.0 32 bit

Steps to Reproduce
Clone the repository and try to build example1

Screenshots

Suggestion
Add minimum requirements to README.md file.
Or
Use C++14 in qge/qge.pri config file

This hierarchy needs to be redone.

Item needs to go in a map, thus it needs to be an Entity. Not all Entities should have an Inventories and Slots. We need to create a subclass of Entity that has these capabilities. Let's call that subclass "Actor". Here is what the hierarchy should look like:

from example 5 and and so on in the others...
I tried game->diplomacyManager().setRelationship(0,1, qge::Relationship::ENEMY);
but spider doesn't move.

regards

Every single entity can specify what classes can and can't damage them through run time type identification. This is weird.

• give Entities two functions: one called nonFriendlyDamage() and the other called friendlyDamage().
  • nonFriendlyDamage(Entity* entityToDamage, double dmgAmount) will only damage if the said entity is an enemy
  • friendlyDamage() will damage said entity even if it's friendly

This way, whenever one entity wants to damage another (irregardless of how - via weapon, ability, etc) it does it through this API. If it is an ability/weapon/etc that deals friendly damage, they can use the friendlyDamage() function, otherwise the nonFriendlyDamage(). This is an excellent idea! I'm a genius!

I tried to built in 5.12 QT version to make it work in ubports , the build library works but not working. i noticed that it used QtWidgets which is problematic on ubports device . is it possible to create QML counterpart of this ? thank you

Often, frames in sprites are much bigger than the actual content (i.e. there is lots of transparent edge/border pixels.). We currently use the entire image as the bbox, which makes collisions seem weird. We should have functionality to extract more accurate bboxes from frames.

It is 58 mb, too damn big! The vast majority of the size is most likely due to image/sound files.

If the image/sound files are indeed the culprit, we should remove the images/sounds we don't use in the examples. Alternatively, we can remove almost all of the images/sounds, and then put them individually in each example.

We need a logo for QGE.

The logo should represent the fact that QGE is very "component" based, i.e. you plug various components together to create a new component with interesting behaviors (e.g. plugging EntityControllers into Entities).

Some ideas for a logo:

• placing the letters Q, G, and E into different puzzle pieces
• making the letters Q, G, and E into gears (and/or other hardware parts) that are somehow joined together

Do something like this:

Entity::setOrigin(const QPointF& newOrigin){
  origin_ = newOrigin;
  sprite()->underlyingItem_->setPos(pos() - newOrigin)
}

We need to create a series of videos in which we walk through building a basic game using QGE.

We can build the same basic game described in the "example projects " (see issue #2)

Basically, create a game with a moving player, some body thrusting enemies who drop items, and an entity to buy items from.

Hey,

The spider entity will not move even when the player is in the field of view. The issue is PathingMap is not registering just by using qRegisterMetaType<PathingMap>(); //(Line 45 in Game.cpp)

qRegisterMetaType(); requires that you first declare the struct using Q_DECLARE_METATYPE()

Using this instead of the above solves my issue.
int qRegisterMetaType(const char * typeName)
i.e. qRegisterMetaType<PathingMap>("PathingMap"); //I was able to find this using the Debug messages.

Love your work,
Thank you,
Abhishek

Do a search and replace in the entire project. Search for ECCheckFOV and replace to ECFieldOfViewEmitter

First of all, if the license is missing, then the default "All rights reserved" does apply.

However, even if this repo adds like the LGPL 2.1 license file, then the produced games would be too easy to reverse engineer.

I mean, allow users to static-link to the engine, and dynamic-linking to Qt is more than enough.

Running Example8 everything renders correctly, but getting output in QT Console:

Entities have a settable origin property. We should make this by default be the center of its sprite. Add an additional optional argument in Entity::setSprite() that will set the origin to be the center of the sprite.

• make field of view start at origin of entity not (0,0)
• entity doesn't seem to actually thrust, it just makes a noise and damages
