Amiga Game Development series

[mcgeezer]

Hi all,

Some of you will probably have seen I have started to do an Amiga game development tutorial series (I've actually been meaning to do it for a while).

As there is an awesome pool of talent here I would like to extend an invite to the amigagamedev discord server which is at https://discord.gg/BMfKJHE

For those who want to follow what I'm doing on the series you can go to http://www.amigagamedev.com, or if you are social media inclined https://fb.me/amigagamedev/

As part of my tutorial series I'm offering support on coding and stuff like that (not like you will need it)... but please drop by if you have any questions or simply want to get involved. There is already a good few people there now so it would be lovely to have the cream of the Amiga 68K join in.

Thank you Graeme.
Will take the time to watch your video (& follow the tuto)

[SteveMoody]

Looks interesting, will have to check out the videos as soon as i get a chance.

[spacey]

awesome! i'll definitely be following this

[activist]

Fair play for the huge effort getting this going

Episode #3 is now uploaded.

I'm not going to link to all the content... but I'll do the video and website.

Well,I'm not centered around amiga hardware but if interested in game programming in general for any system,I might be doing a information of sorts for games(AI logic,control) with source code if a few people are interested I'll explain with code how it was accomplished.You might be able to use mcgeezer tutorial with my information.

I think that's a great idea. Knowledge is power!

I like the idea of doing asm and C source too. C is great for "seeing" the logic.

Many thanks for creating this tutorial!

Is there a manual for this version MonAm available?

I've two questions about it - maybe you answered them already in the tutorial and I just did't notice it:

- After changing the address of the 'Disassembler pc view' using the 'm' key - how can it be switched back to display the current pc address?

- Can the register view somehow switched to display the contents bit by bit?

Yes, i’ll put the manual online tonight.

You can change back to pc by pressing m and then pc [enter]

Register bits... maybe, i’ll take a look, not sure why u would want that though.


MonAm manual - You'll want page 180

Thank you, that's what I was looking for

[malko]

Already "episode V" (Graeme strikes back ).
Thank you !

Thanks for this tutorial! Meanwhile halfway through episode 5 and I've learnt a lot so far. Really looking forward for more stuff to come;-)

One remark. 'though: With the Episode5 files I tried to load a picture which I saved with the Amiga program Brilliance. I noticed that the CMAP header of this picture wasn't found in palette.asm / agdGetBitmapPalette.

The reason is that Brilliance has some long extra chunk after FORM which is like:

   ILBMANNO   "Written by Brilliance Release 2.0

So, in agdGetBitmapPalette I had to change the line

    move.l #40,d7

to

    move.l #80,d7

for the CMAP to be loaded. But this is no generic solution, and I don't know if this would be a problem if a really small ILBM file is loaded.

[mcgeezer]

Thanks for the feedback and you have solved the problem fine, the 40 length just acts as a canary in case the cmap isnt found in the header and it goes off searching all memory eventually leading to a crash.

[mcgeezer]

I did a a rather rough and ready tutorial tonight on how I go about debugging with MonAM, WinUAE and the AR4 Cart.

It might help a few people with coding here so just posting a link to it.
