FOV, seems possible...maybe with a distance formula with onchange(x,y,z) events and viewed property in table each cell. No lighting for now though.

I too prefer the side-view style for a game such as this. Do you plan to have some sort of field of view code, or something equivalent such that people can only see area's they have been in before? I think that would be cool and useful, and it would make exploring caves and stuff more interesting because you don't necessarily know what is coming up, and you would have to dig and explore to find minerals and stuff.

Can't wait for some screenies!

side-view seems perfect indeed.

By field of view, do you mean like fog of war in Joltima for the 83+? That would be interesting, although would it cause lag?

I don't think field of view should present too much of a problem - it may even help reduce the number of sprites to be drawn if you do it right.

DJ Omnimaga · « **Reply #34 on:** April 10, 2012, 10:54:47 pm »

Oh, right, I didn't think about that part. Draw black tiles instead of actual sprites. But I'm a bit concerned about the complex algorithm. Is that complicated to implement such thing in any language? I remember Michael_Lee tried something similar last year in his game Light and it was extremely slow. Joltima, on the other hand, manages to do it fine and the Nspire is 120 MHz.

Builderboy · « **Reply #35 on:** April 10, 2012, 11:19:09 pm »

I think with this game it could be implemented in a much different way that would actually be better and faster. The way I would do it is to have all tiles in the world either hidden or visible. The tiles above ground would all be visible, and all the tiles below ground (including caves) would be hidden. Whenever you are able to see a hidden tile, it would become visible permanently, that way if you explore a cave you would be able to see all the areas you had already explored, and the areas you haven't would still be dark.

leafy · « **Reply #36 on:** April 10, 2012, 11:49:33 pm »

I know in Terraria it's more like any tiles around you or a light source show up, and those that don't fade to black.

linuxgeek96 · « **Reply #37 on:** April 11, 2012, 12:13:31 am »

builderboy, that seems like a good idea. I'll try that. BTW, the other method didn't cause all that much lag, but this is better (and easier to code).

DJ Omnimaga · « **Reply #38 on:** April 11, 2012, 12:43:28 am »

Leafy do you mean some kind of circle like if you had a flash light?

UPDATE:
Hi guys,
It appears I promised an unrealistic release schedule. I'll work like mad to keep it today, but chances are I'll upload on Saturday or even Sunday. :-(. But on the upside, I have lighting working, mining partially working and inventoruy partially working. If anyone has a 7x7 iron ore sprite, it would be appreciated (writing sprites by hand on the calc is hard!).

If you don't get an upload by 2:30, you know what to expect now.

The function on.paint misses an END (you can see this fairly easy with notepad++). I added it, but all I can see is a blue screen...

I would also recommend (apart of indenting the code) is that since I saw several pieces of code that repeats, it should be good to identify them & create a function for them, like for example, the color picker.

Something like this could do:

Code: [Select]

function color_picker(gc, top)
    if top==0 then
        gc:setColorRGB(255*d,255*d,255*d)
    elseif top==1 then
        gc:setColorRGB(150*d,100*d,50*d)
    elseif top==2 then
        gc:setColorRGB(150*d,150*d,150*d)
    elseif top==3 then
        gc:setColorRGB(200*d,200*d,200*d)
    end
end

^This can be optimized, but I think is ok for now...

This will make the code more legible

There are many things that can be changed, but the most important thing right now is identation.
Getting used to it will be a very great help. Do not under estimate it

You will also see your bugs much clearer.
