Game Making & Editing FAQ/Q&A

When two or more Users need to stream content to the same Twitch account the way to do this safely is to use the Permissions feature "People who can stream to your channel" rather than sharing the Primary Stream Key and/or account information to 'authorised' parties. Notwithstanding general security issues, using the "People who can stream to your channel" option makes account sharing redundant.

Note: People who can stream to your channel does not grant general account access, it only permits direct streaming. To manage an account check the various 'moderating' or 'editorial' setting or options.

Streaming Invite

To set up another person to stream; in the Creator Dashboard click Settings and then Stream. Scroll down the page to the Permissions section. Here, mouse over the "People who can stream to your channel" area to highlight then click. This displays the People who can stream to your channel panel (when doing this Twitch highlights the Channel menu option).

In Twitch Creator Dashboard access the Stream options under Settings

In the Enter an email address input field type the email address of someone who to be granted access to direct streaming and click Send Invite. Twitch will send an invite with a unique stream key (invited emails are then listed below the input box).

Scroll down to Permissions and click People who can stream to your channel option to send an invite (and to list/manage access).

Accepting Invite

On receiving the invite the unique stream key then needs to be copy/pasted into the stream settings of the app used to livecast to Twitch. How this is done differs depending on the app and the way account access is actioned, for example, in OBS Studio the stream key is dropped into the Stream options under Settings alongside the ingest URL rtmp://live.twitch.tv/app/;

Service - Custom...
Server - rtmp://live.twitch.tv/app/
Stream Key - [key from email invite]

Note: in OBS Studio the Service parameter must to be set to Custom... else Twitch login details will be requested - OBS assumes the User is streaming to an account they own or have access to. To stream to another account without login details (recommended action) OBS must be forced to stream directly to the default ingest for Twitch, which then correctly routes the incoming data where it needs to be.

Once done, upon going live, streamed data will be sent to the Channel associated with the invite, further being managed by whomever has account or editorial access.

The email invite sent from Twitch will include a unique stream ID associated with the account


In the streaming app of choice the unique key sent from Twitch needs to be dropped in place - where this is done may differ app to app

Q: Is it legal to recreate a game level for your own game?

A (short): In a word, "no".

A (long): There are various answers on the interwebs from more experienced game developers that, correctly (and notwithstanding IANAL) caution against 'copying', 'duplicating' or in any other way 'recreating' a level or levels from one or more game(s) into another, especially if the final product is being monetized, regardless of form that takes (adverts on a download web page constitutes 'monetization'), or at the very least competes with another licenced properties 'brand awareness' (the 'brand doesn't even have to be an active property).

Q #2: What's the big deal? It's not like a levels layout is a thing!

A #2: Well, two things (amongst others) to consider;

1) the design or layout of a level is an artistic or aesthetic expression the same way assets, themselves subject to copyright, are used to express or tell a particular story through interactive means (a level is an asset in this literal sense). Levels are the formative background space of the 'story' that prompts player-responsive actions, just as a movie or theatre production set piece, and differs from the experience of a game itself, the emergent and dynamic play, directed as that is by the way players behave depending on who they are and how they react to stimulus.

In other words, game levels and layouts don't exist outside an expressive story-telling process, ergo gipsum-lorry (said the badly programmed Architect), they're subject to protection (even if that's just at the authors insistence).

2) and probably the most important; the designer wanting to replicate a particular design isn't the one to determine whether something is an infringement or not, the Property owner does; they issue a claim against the alleged infringing party with an eye to prosecute should they need to.

In practice this question of 'replicating' a level is at heart a 'fan art' issue, which is similarly contentious and troublesome; although other game developers engage in it, it doesn't make it "legal" to do. It's not. Just ask the mod team behind Alien Quake about getting FOXed.

And finally, understand that "Fair Use" is a defence, not a claim over, or 'right', to do something.

Although quite long in the tooth now Gmax can still be used to mesh content for various games (in particular Flight Simulator 2002 and Flight Simulator 2020), although a few additional steps may necessary in between. With that said, for Windows 10 and Windows 11 there may be some compatibility issues to contend with that crash the application on startup. The likely cause of this is the Gmax using the wrong viewport driver to render content, that's the HEIDI (software), OpenGL and Direct3D (hardware) selections typically accessed from Customize » Preferences » Viewports - Display Drivers, which can't then be accessed and changed. When this happens a workaround can be used to add a 'flag' to the Gmax shortcut forcing the gmax Display Setup dialogue to appear so the correct option can be set.

To set the flag, right-click the Gmax Desktop icon and select Properties. In the Shortcut tab, append " -h" (note the space before '-h') to the Target: file path e.g.;
"D:\Program Files\gmax\gmax.exe"
Becomes
"D:\Program Files\gmax\gmax.exe" -h
Optionally, for Windows 10 and Windows 11 set the Run this program as an Administrator checkbox in Compatibility options.

Click Apply then OK to close, then restart Gmax. The gmax Driver Setup dialogue will appear. Set an option; HEIDI, OpenGL or Direct3D (HEIDI is initially the safest to verify the application starts and no other issues are in affect). Once the application starts up correctly the driver can be changed if needed in Customize » Preferences » Viewports - Display Drivers and the shortcut flag removed.

IMPORANT: the likely cause of the issue is the version of OpenGL Gmax uses to drive the viewports, which is obsolete or incompatible with the latest versions of the API. This is especially so for AMD powered graphics systems - setting OpenGL as the driver typically won't work so the driver should be Direct3D (hardware) or HEIDI (software).

Setting the Desktop shortcut flag to force gmax to start in 'safe mode'.

With the Desktop shortcut flag set the gmax Driver Setup dialogue appears with three options; HEIDI, OpenGL and Direct3D - HEIDI is the safest.

Gmax open and running on Windows 10 once driver is correctly set

Notwithstanding 'bricked' devices, with the termination of ALL Blackberry OS10 and Playbook OS related services in January of 2022, attempts to setup devices AFTER this date will likely fail at the Network Connection stage or during User Agreement as a direct consequence of failed attempts to connect to services that no longer exist in order to complete the setup process.

For the Agreement in particular, as this document changes from time-to-time it was hosted and updated remotely and now that its no longer available, nothing loads onto the device and nothing can be agreed with or declined, essentially 'bricking' the device despite being powered on and progressing though setup (working).

At time of writing there is no fix or workaround for Playbook devices being stuck during setup as it's unlikely RIM will re-enable services to grant access to legal documents that may hold them liable for services no longer provided.

Given the buzz surrounding bitcoin and cryptocurrencies generally it's only natural to ask "is it really worth mining for bitcoin" and just what is "the truth about bitcoin mining". Well, TL:DR; it's not really worth doing except for the fun of it, the experience, or as an exercise in it's own right [00], largely because mining is now done at such a colossally industrial process, all that remains for the individual are the metaphorical scraps that go unnoticed, largely because they're not worth picking up.

So, is it really worth mining for bitcoin using a personal computer?

Short answer is "no".

Long answer is "not really".

Assuming the question is being asked from the average normies point of view, a person just wanting to use their computer, laptop or mobile device to mine rather than hardcore miners using dedicated ASIC hardware designed specifically for the job, before mining for bitcoin the digital prospector has to consider the following;

• The cost of electricity needed to run the equipment.
• The (current & future) price of bitcoin (or whatever hash is being mined, the 'coin' herein).

While both concerns are important for figuring out whether it's worth mining for bitcoin, the first, the cost of electricity, has greater influence over a decision to mine than the latter, the price of bitcoin, because power prices determine running costs of mining equipment, which in turn defines the break-even point for resulting return of investment/value (RoI/RoV).

Simply put, if it costs more to run the hardware used to mine coins than current rewards from mining then it's simply not worth doing, except as an exercise in its own right, because the prospector is more-or-less always then running at a loss.

In other words then, as of writing the only way it would be cost effective, even 'profitable', to mine bitcoin is through use of 'free' electricity, not in the ‘someone else is paying for it’ sense, but rather power that is supplied locally, perhaps as self-owned solar, wind, water etc., anything otherwise generated 'off-grid' or in the proverbial backyard. If this is the case then there is no 'cost' against which mining needs to be leveraged (notwithstanding costs associated with maintenance and upkeep of all the hardware used in the process, from solar panels to graphics card et al) so bitcoin mining can be done full steam ahead.

With that said, in terms of profitability/RoI/RoV, the aforementioned is compounded further by;

• The rate at which mining occurs [1].
• How much reward there is for doing said mining [2].
• If there even is a reward for doing so [3].

What this all means in practice is this; coins are generally highly divisible by nature, some by as many as twelve decimal places e.g. 0.000000000000 or to the trillionth decimal. So whist their availability may be exponentially greater than other (fiat) physical currencies like the US Dollar, it means the potential share per mining session is going to be relatively small, even accounting for inbuilt scarcity that underwrites the value of cryptocurrency as a whole. In other words, whilst a successfully mining session might return 35,000 'points', if the sessions results are even accepted on the network, that might translate to earning 0.000000035000’s (35 ten-millionth’s) of a coin. If said coin has a market value of $100.00, the 35,000 rewarded 'points' would be worth fractions of a fraction of a cent (tens or hundreds-of-millionth’s or billionth’s) – the coin itself would have to be worth high millions, even billions or trillions for any mined points to be reasonably convertible to cash of any value for the costs and effort used to mine it.

And this is where the dilemma occurs for ordinary people wanting to mine bitcoins with their computers or devices, it’s simply no longer economically feasible if power is being fed in from the grid and has to be paid for; it will cost more to mine than can be earned from mining [4].

The bottom line on mining for bitcoin these days is this; it’s potentially more profitable to simply buy and trade bitcoin or hold on to it to capitalise on potential gains from exchange/commodity increases, especially as Governments the globe over are turning to digital currencies knowing their cash reserves are falling well short of their debt obligations.

Footnotes:
[00] There is another reason for mining and that's to acquire coins in the present as a bet against a future price rise of the coin mined. In many ways mining cryptocurrencies with this in mind is akin to purchasing stocks or shares, owning gold, silver etc., or owning other price-based commodities where gains can be had if the price of the item held increases. For crypto this essentially means betting the current costs of mining against future price increases. Cryptocurrency mining with this in mind generally means being more selective with coin choice as not all crypto is equal, the more popular a coin is now the less profitable it is in the present.

[1] Mining bitcoins tends to cycle hardware to its limit – looking at Device Manager in Windows for example, will typically show mining software running at between 70% and 95% CPU use depending on where the calculations are in the process and/or whether the computer is doing something else at the time (like opening and viewing Device Manager). It should be noted that mining bitcoin using a CPU tends to be more energy intensive than mining using a discrete graphics card (CPU vs GPU mining). It also producing more heat, uses more power typically have a lower session throughput.

[2] The reward for mining sessions depends on what’s being mined, it isn’t fixed in the sense that ‘X’ outcome occurs with ‘Y’ input.

[3] Depending on the mining software, pool network and other factors, mining is typically 'sessions' based that can last from a few minutes to a number of hours. Each session has to be completed in full for the miner to have any change of earning a return (hence mining often being compared to entering or participating in a lottery - there is a high degree of chance involved, especially when working as a solo miner). This is also conditional on the results of the session being accepted. If not, and sessions are rejected, no earnings occur so all the costs incurred for that sessions, the electricity used etc., is essentially lost.

[4] Most bitcoin mining now is done in locations where electricity is cheap enough that none of the above matters, by institutions that supply their own power, or those that are heavily subsidised.
