    Brains. A computer. An operating system. A compiler.

    If you need help with it, please post more specific information on what you want to do.

    She was so Blonde, she spent 20 minutes looking at the orange juice can because it said "Concentrate."

    When in doubt, read the FAQ.
    Then ask a smart question.

    Cool

    alright, see...i've got this cough cough...disability. i read & took good notes on the entire 1st semester course in C. step by step. i just have this problem...where i have to go back afterwards and study the entire thing all over again...part for part...section for section by any means necessary...and i have most of it understood and in use...it's just i'm one of those people that take 5 years to learn a one semester course. well, it's a learning problem. i need hands on...man, hands on training...i can dooo so much with C...i just cannot make a photon weapon for a spaceship in msdos. i can do it...i've done it six different ways in the past...i want the standard way of creating "bullets" for my spacecraft this time...to bury it into my mind...as permanently as possible...the code...i have to have the code...i'm tired of doing it allllll wrong!!! help, man.

    And did you save it the last 6 times you did it? Show us how you did it then. It is always easier to start with something.

    >> want the standard way of creating "bullets" for my spacecraft this time<< I don't think the C standard say anything about photon weapons or bullets.

    that leaves a lot of questions unanswered. are these bullets fast, or do they scroll across the screen like other projectiles?

    if you need help this badly for this, have done it five times before, and still cannot get it, you probably should find another occupation. (or hobby).

    well, they sucked. embarrassing. totally. they worked fine. it was back when i was using cleardevice(); like an idiot to make thing animate...just plain ignorant...e.g.


    putpixel(x,y,color); it just sucks i cannot even explain it...it would increment x or y, or both...in a plain shooting game firing straight upward...along the x axis. zzz...zzzz...now i have a ship that flies in circles...and i cannot get the bullet to even fly along....ahahahaha i suck sometimes...it's a mental block. i'll try to explain it again later...i just quit smoking cigarettes a week ago...typing kind of get to me right now...i'm going to take a break for bit...it was hit e.g. alt and it would launch the pixel into like an unlocked mode...then from there in the program there would be an incrementation of the y axis. really retarded like.

    i'm looking for fast bullets, they were not. actually, this hobby issss very very good for me...you see...i have some gift at it...like with anything else...i'm a god for 2 days...the rest of the week i'm a dolt...like today. i'm this way with everything there is in life....

    Cool

    well, you know...i cannot even beat the games i create these days...they are difficult. i have an imagination. i just have to continue to evolve in my practice...once i gain this photon ability...the evolution can take its toll...and rid my of these programming ills...it's the final process. for god's sakes man...please lend me a hand in my darkest hour...

    i don't know what that's all about; i found a thread on the subject of bullets though...so, it's physics? whooooowhooooooooo...big deal. you could have just said so. it's a start.

    by asking nicely and using code tags

    and asking the moderator to delete all your nonsense posts

    Done.

    First of all, we know nothing about your project. Please sort your thoughts and questions, assume we don't have your knowledge and repost them. Use short sentences and paragraphs, so we can easily follow your train of thought.

    What do you want to do ?
    What did you do ?
    What happened ?
    What would you like to change ?
