Toying with COS & SIN commands to produce 2D effects.

[erico]

That list is quite promising!
I´m particularly found of:

Shapes - vector images from my idea of what can help quickly to outline your idea
Built in animator.
Built in canvass - draw them on screen and see how they look - you can cut a group out and save them as oe sprite.

Things from some other places I find interesting:

light table for animations
stencil for the outlines, easier to color something?

I´m not really sure ´redo´ is needed, like if you have a spare screen or an animation set, you can use other frames to test variations. IMO

Again, it feels quite promising, how long till you believe it will be ready to ship?

[I love my Brick]

Im posting the "PAC MAN" code here that I lost interest with. There are a million such clones out there and this slowly sank into my mind.  So, I changed a few things, the ghosts see through walls (C`mon, Ghosts cant see through solid matter?) and home in on you - resulting in a very difficult challenge. I had planned a maze that took skill to master without loosing lifes but time/life/another clone of it etc put me off.

You will find in this code a prog that allows you to explore the maze with moving ghosts that hunt you.  Erm, thats all I`m afraid.  Ive substitued LOADSPRITE with bland blocks. 

Theres no pro code here folks, just a foundation I typed up over several evenings to get things running.

If any of you admire it, explore it and make/add changes.

I will sure check this out later.
That data statement there gives me itches as I use similar stuff to draw solaris map(board game) in a way that editing it creates newer maps.I took me ages to understand DATA capabilities back on the COCO days, so I´m quite found of its uses.

Don´t let down because of other/similar games, I´m sure you can beat others attempts or even better, add to the pot.
One successful ´pac man´ always open doors and call attention to other versions too.

You could make into a ROGUE LIKE PACMAN... such a game would make my day

But I´m just being cheerishable, I certainly understand the life/work/things/other ideas detracting us to pursue one idea.

((All the routines I have described work. The fill routine was a right bugger though and held me back many evenings in coding it.  Setpixel can be very slow when measured by Getpixel....I found a work around that reduced my previous idea and allowed a fast fill inside a polygon.  I was left with a bugbear about GLBasic.))

Right now Im adding new ideas that have sprung from the development of this prog.

I try it out on my Son and Daughter and they tell me what needs to be added. (My Daughter told me to add stencils - pacman,invader,coin,diamond etc) My Son just loved it and really liked it when he saved his images and then printed them on screen.

So, I`m working with my kids on this one & sometimes they think out of the box and surprise me by thier idea.

Great words!

Children love & embrace the world whilst we adults worry about it & the mistakes we make.

Ah well, back to my brick Just glad Im not a real priest - feck, that must be an even harder life.

Sure, I agree and that will happen. Just a few more tweaks and improvements to go - almost there. The more you complete something the more you find a way to stream line other areas of your code. I hate to say this but, Math is fun! If my younger self could see me now

I will remove the colour picker sound effect and all others before I submit the prog here.  The kids love the sound effects but us adults may find them distracting.

Im posting the "PAC MAN" code here that I lost interest with.

I've compiled it, nice stuff!

I've assembled the first few codesnippets into one bundle.

Also I've shot some screenshots:
