##### Computer Programming / Physics help
« on: June 23, 2011, 09:18:10 am »
this question could really go anywhere dev-related, but since my game's being programmed in java i put it here.

Are there any equations which, given a constant horizontal speed, will give a gravitational constant and an acceleration constant (intial upward velocity for when the character jumps) given that the height and length of the jump must remain constant?

i.e., i've programmed my game using a speed of 3 pixels/frame and tweaked the upward velocity and gravity until i liked the height/length of the character's jump. now i want to be able to have a speed of say 6 pixels/frame and have an equation which calculates the upward velocity and gravity so that the height/length of the jump isn't changed from my 3 pixels/frame speed.

i know that x = x0 + v0t + .5at2, but i am unsure if that can be applied in this case, and if so how.

thanks for the help!

unless you're in college, you can't enter it, but i thought that some of the problems might appeal to some of omnimaga's computer programmers. they're part of an international collegiate programming contest, so they are anything but easy. you can find links to the "problem sets" here. i found a relatively easy problem here, as problem D, bipartite numbers.

##### Computer Projects and Ideas / FreeCell
« on: January 28, 2011, 10:48:22 pm »
i've recently took a liking to FreeCell and decided that since it isn't too complicated a game and i was a little bit over my head with Juggernaut, i'm going to make it in java. all of the cards can be moved in arbitrary sized groups to other columns. no game-play is implemented yet, but the roots are there. also, in the screenshot there's a 6 and 5 that are floating. my mouse was there, but was taken out for the screenshot. drag-and-drop is how it's played.

i need some help. i'd like to make a website for my game juggernaut, but i have no idea how or where to get a domain name.

##### Computer Projects and Ideas / Juggernaut Map Editor
« on: December 24, 2010, 03:15:28 pm »
hello omnimaga, as some of you know i'm making a game in java called Juggernaut which will require many maps. within the next week, my map editor will be functional enough for you, the user, to create maps and receive a string of numbers which i can use. if you're interested in making maps for Juggernaut, PM me. you'll be mentioned in the readme if i use your levels.

##### Art / 24 x 24 crumbling block request.
« on: December 20, 2010, 07:32:53 pm »
hello. i am in need of a 24 x 24 full color tile of a block that is about to fall apart. the palette of the block should match my game Juggernaut. a good screenshot is posted in that message for reference. You will get credit.

my friend just brought this to my attention. it's a play on words, and everytime you say the word "happiness" you will think differently.

Spoiler For are you sure?:
Spoiler For seriously. once you see it...:
Spoiler For ... you cannot unsee it.:
Spoiler For you asked for it.:
You can't say "happiness" without saying "penis".

well, here he is. is there anything different you would do to him? pretty soon i'll get him a running animation.

##### Axe / Bit checking
« on: December 08, 2010, 10:29:24 pm »
i can't figure this out for the life of me. run this code and please tell me i'm sane:

Code: [Select]
.PDisp (1e7)>Dec     //euler's eit displays 7 for me. but it should be displaying 1, am i right? because 1 in binary is 0000 0001 and the 7th bit starting from the left like the documentation says is set. i have axe 4.6. Builderboy on IRC tried it with 4.5 and it displayed a 1.

##### Computer Projects and Ideas / Juggernaut
« on: December 06, 2010, 10:59:00 am »
Hello, as some of you may know i am making a computer game in java. its name is Juggernaut. it's going to be similar to a cross between zTrumpet's Exodus (level-wise) and Valve's Portal, combining both their storylines.

Juggernaut is a platformer in which you are an alien and you crashed your ship on an unknown planet. the Juggernaut (supreme force on the planet) has taken you hostage. the Juggernaut enjoys watching people go through trials, and so you have a series of rooms similar to zTrumpet's exodus levels. these are the levels where you learn the controls and rules of the game. then, similar to portal, there's a tricky level in which you were meant to die, but if you play it right.. you escape. then the levels get substantially more difficult and soon you escape, only to be confronted by the Juggernaut, who has stuck you in a timed level, where you must think faster than the clock to escape, and end up stealing a ship to go home.
here's a screenshot of the title screen, it's rather dark. the blood drops fall at differing velocities.

a calculator port is possible and would be written in axe, but wouldn't be started until at least february 15th (the deadline for the contest this project is in).

##### Art / Racetrack Sprite
« on: November 29, 2010, 05:28:41 pm »
i was messing around with the program below, and out popped this picture. it looked kinda cool, so i thought i'd post it here. best part? the tracks are 8 pixels tall (:

Code: [Select]
ClrDraw[FFFFFFFFFFFFFFFF]->Pic10->D->FRepeat getKey(15)If F:D+1->DElse:D-1->D:EndIf D=0 or (D=-88)F xor 1->F:EndC+4->CPt-Change(88+D,sin(C)//6+30,Pic1DispGraphEnd
edit: will upload a PNG of it soon

##### Art / full color sliding animation
« on: November 25, 2010, 01:45:07 pm »
hello. i am making a game in java where there are physics as such that you can slide around. however, i do not have a good sliding image. attached is the spritesheet i am using. i need that character in a sliding pose. not like in a baseball game, just like he's coasting to a stop. also, if you want to add in a couple frames in the running animation sequence, then i would not be ungrateful (:

edit: and if you use paint and can't get transparency, just make the background white.
edit2: they're 20x20 by the way.

##### Axe / 4-level grayscale sprite editor
« on: November 24, 2010, 06:39:55 pm »
edits 8x8 sprites.

[2nd]   to toggle the buffer pixel
[Alpha] to toggle the backbuffer pixel
[clear] to quit and export hex to Str1

hex is formatted like so:
[(buffer hex)](newline)[(backbuffer hex)]

##### TI Z80 / Triangle Solver
« on: November 22, 2010, 05:05:24 pm »
Triangle solver! (this topic is so if i RAM clear my calculator, it's no big deal cause it's now online)

this is a graphical triangle solver. if you give it 3 pieces of information, it will give you the other 3. it has no error checking, so if you get err: domain, the triangle probably does not exist. do not give the triangle solver 4+ pieces of information, it is not smart enough to handle this. it assumes you put in 3. it will solve the following conditions: SSS, SAS, ASS (wait, what?), ASA, AAS. it will also tell you if your triangle is ambiguous, but it will sadly not give you the second triangle. it will however, store the complement of the first angle solved into the variable M and then you can solve for the second triangle by running the program again.

um.. yeah. it's handy. and under 1000 bytes (hooray! goal met!)

##### TI-BASIC / Routine request.
« on: November 19, 2010, 05:45:20 pm »
i need a routine/snippet of code to, from a list of 3 elements, two guaranteed to be an arbitrary value greater than zero, and one guaranteed to be zero, return index of the element with 0.
so {235,532,0} returns 3. {0,532,25} returns 1. {235,0,18729} returns 2. assume this list is {A,B,C}.

i'm looking for size here, not speed.
if you have a more elegant solution, please post it.

edit: here's what i have:
Code: [Select]
max({A=0,2not(B),3not(C   //nazi.
