Hello! I'm working on this project from a couple of days in my spare time(when i'm not genetic engineering my mind or breaking my bones breakdancing). As you can guess it's a pokemon FR/LG clone, a 2D tile based RPG.
Until now i've done the map scrolling, player movement, sprite-sprite collision and messages.
In this little demo i've overcharged the draw function by printing 300 tiles per frame in order to minimize the FPS.
Please, let me know your FPS (shown in the window caption) when running the game... It's important for me to know the minimum speed to improve it... Please!
Uh, hints are also well accepted, so don't be shy !
EDIT:Here's another release with:
-Map movement/scrolling
-Messages
-Choices
-Map transitions
-Map teleporting
I've uploaded also a PSP version (with LuaPlayer Euphoria and a LOVE>LPE translation script), but it runs very slow and lacks of a transparency and image stretching system...

Re: Pokemon Clone
Bit concerned it being a .exe at this stage, didn't want to run it at first.
You should add collision boundries, as I could walk off of the map.
FPS wise i'm getting a constant 30, seems to be capped.
Very nice start, and good that you posted with content to show that you've made progress, even though I had to run the game to see.
Hope it goes well for you.

Re: Pokemon Clone
It's funny: 'love game.exe' makes the game run under linux
lg.newImage("cat.png") -- made possible by lg = love.graphics
-- Don't force fullscreen (it frustrates those who want to try your game real quick) -- Develop for 1280x720 (so people can make HD videos)

Re: Pokemon Clone
Yeah, it works in OS X as well. I just can't view the code.
Mine runs at 28FPS. Only 300 tiles? My game at 800x500 draws 400 tiles plus more on two other layers plus a bunch of NPC's and enemies and the player and all projectiles at once and still runs 55FPS. How can yours be going so slow with only 300 tiles? Or did you mean 3000?
How fast does it go when you aren't "overloading" it?
Also, what do all those DLL's do? Are they actually being used for the game? Because if so, somehow LÖVE is still using them even on OS X. If not, then that's a lot of overkill.
Edit: Nope. The game does not need all those DLL's or ANY of those other files. Why are they in the ZIP file? You can delete them all. Did Microsoft put all those unnecessary files in the ZIP file when you uploaded them? Delete that crap. All those DLL's are unneeded by your LÖVE game.
All gone. Trashed. Deleted and Baleted.
Edit: Well, this is INTERESTING. If I try to run your game.exe in Darwine (An OS X version of WINE, a non-emulator Windows simulator) it complains that the DLL's are missing.
But somehow LÖVE alone is able to run the .love file buried inside the EXE. Something tells me whatever program you used to create your EXE requires all those files. Frankly, I find that excessive, but hey, I don't use Windows so it's nice to know I don't need them.
You learn something new everyday.
Edit: Another update, running the game in Darwine with the DLL's in place also gets me about 28FPS. Nice to know Darwine is able to run LÖVE at "full" speed.
Edit: Ah, I see. All those files are required by the LOVE.EXE file on Windows. I see. Glad I don't need all that extraneous stuff on OS X.

Re: Pokemon Clone
getting 28 as well. seems capped, and the movement feels "heavy" at that speed. may want to speed up fps or the character huh. otherwise though, its looking good
Re: Pokemon Clone
Uh oh... By 300 tiles i didn't mean that the map is made with 300 tiles, but that with the 240 X 160 resolution the visible tiles are 150 per layer and i'm drawing 2 layers. I could have made a 1000000 X 1000000 map without speed loss, 'cause the engine only shows visible sprites/tiles. The dll's are included in the zip to let the game run also on computers without love installed... Nice to see that the game runs at full speed! I'll post the .love ASAP, simply replacing from skydrive the .zip(i'm sorry, i didn't want to hide the code). Regarding FPS i've thought that 60 would be better, but the player walks too fast (1 pixel per frame at 60fps is like it's running instead of walking)... Any idea? Thanks anyway for the support! Ah, and sorry for the starting message in italian... I'll fix that later!

Re: Pokemon Clone
Actually... you do need them (well, not the .DLLs...), but I think that for OS X the libraries are either statically linked or included in Love.app (is that possible? I have no idea how those things work.).Jasoco wrote:Edit: Ah, I see. All those files are required by the LOVE.EXE file on Windows. I see. Glad I don't need all that extraneous stuff on OS X.

Re: Pokemon Clone
I was trying to change the FPS to 60 and to decrement from 1 to 0.8 the movement of the player per frame, but i've encountered a BIG problem. This is a simple example:
This code works:
This one instead isn't working:
In the second example the loop ends correctly but the message isn't displayed. Why? I'm pretty sure that 0.8 * 20 == 16, so there is no way that a becomes > b inside the loop...
This code works:
Code: Select all
a = 0
b = 16
while a < b do
a = a + 1
end
if a == b then print("OK") end
Code: Select all
a = 0
b = 16
while a < b do
a = a + 0.8
end
if a == b then print("OK") end

Re: Pokemon Clone
Unfortunately, in the world of binary 0.8 * 20 ~= 16. See Wikipedia. You could change it to be a little less exact:
Code: Select all
a = 0
b = 16
while a < b do
a = a + 0.8
end
if a > b - .01 and a < b + .01 then print("OK") end

Re: Pokemon Clone
Yeah, that's what I figure. Whatever utility Windows users use to create an EXE by merging the .love file with the love.exe will still require the DLL's. On OS X the "DLL" equivalents (Frameworks) are all included in the binary.

I look forward to helping out as much as possible. Eager to take a look at the code.napco wrote:Uh oh...

Are you taking advantage of the dt variable (Delta time) for making objects move the same speed no matter the framerate?
speed * dt would give you how many pixels per second the player or whatever should move. That will help you with your FPS. No game should run less than as close to 60FPS as possible. It will be a bit different though for you because you're trying to replicate the tile per step method Pokémon and old Final Fantasy/Dragon Quest games used. Mine uses a more Zelda: Link to the Past move anywhere you want method. It would be easier if you weren't limiting yourself to that method though, but at the same time would open up another world of difficult calculations.
LÖVE is fast enough for very complex things, a complete Pokémon clone is probably nothing to LÖVE. I'm making a Zelda style clone and have been around 55FPS for weeks no matter how many more calculations I put in. The only time it ever goes lower is if I generate a hundred droppables (Items enemies drop) on the screen. (I created a debug function that creates 50 rupees every time I hit A. So yesterday I did a test. I got it down to 8FPS after generating about 10000 rupees.) I've recreated this same engine twice on two different languages now. And each language did it differently.
