added Coop mode:

Quote
cl13:
- Coop added
-> second player is controlled by mouse (left mouse button for shoot)
-> players share their life until one is dead
-> a dead player will be revieved when the other gains 100 life
-> only first player can switch weapons
-> both share the same weapon at a time

release is up to date on the main post as always ;)
i did not test any bugs. if you find something please tell me

a quick info:
i think it may be important to mention some things
  • http://www.microsoft.com/en-us/download/details.aspx?id=40784  if you cannot start the game because dll files are missing (now the 2013 link)
  • if you want to help me with the code posted on github, please write it here, else i maybe wont see it
  • the second boss can only be hit by the third weapon, try to change weapon or fly from left to right (or the other way around) to escape the apples
  • the coop can be buggy at the moment, because i did not have the time to test it
  • i am currently working on adding the boss for the cows, which will be a machine
  • after this boss i will implement buffs, which appear after a monkey is killed (picked random)

as you can see the main focus is on expanding the game. after i have my basic enemy types i plan to make a multiplayer mode (LAN and / or Web) depending on how good i manage to get that going.
For the android users here: if there is an ending in sight an app will be programmed to get this on android

well, thats it for the moment ;)

Nice improvements  :)

Some ideas:
  • Pause
  • Something like a progress bar to show the reload time. So you know when you can shoot again, especially for the thrid weapon
  • Maybe stop the normal enemies to spawn during a bossfight (on crazy its crazy  ;) )
  • Please show the close button in the window. It's annoying to press escape and navigate through the menu just to close the game

thank xou!

i wanted to do a pause option but i do not konw ho i can implement it :(
maybe you can follow my code (i will help you if you want)
reload time for the third weapon is already implemented but not correctly shown
normal enemies spawning durning boss spawn... i will do this
for closing the game, i will implement a button as you wish ;)

i wanted to do a pause option but i do not konw ho i can implement it :(

I would really like to dig through the whole code and help you, but sadly currently I have no time for it  :'(

But I had a look at the main parts and there are 2 options for you.

  • You could create a new state for the pause menu. The pause screen then changes, after a user input, the current state to menu or to game back again.
  • Other option (easier and imo better) (thats how I implemented it in kroniax) you have a bool in the game class like mPaused, and if this is true, do not update all the game objects (player, enemies etc) so they do not move but you draw them with a overlay on top of it (Here you can see an example in C# http://msdn.microsoft.com/en-us/library/bb195026.aspx you don't need to track the pause key :)

I hope I described both ways well enough to follow

Maybe I will have time in about 2weeks during my military service to have a closer look


i will do this for closing the game, i will implement a button as you wish ;)

Why not set the window style to sf::Style::Close or sf::Style::Default and then respond to the sf::Event::Closed event (Would be easier than a button made by yourself  :) )?

okay, i implemented a pause option. but there is a problem i need help with^^

all the movements are bound to elapsedTime = clock.restart().asMilliseconds() in their speed or spawn.
if i pause it stays like this, but if i resume the game, the timer gets very high a moment and that is not wanted, because the game "jumps" forward. my theory is that the clock simply doesn't get restarted. so the longer you stay in pause the higher gets the elapsedTime after you resume. here is the code:

//Game.cpp

#include "Game.h"

HighscoreManager Game::getHighScore()
{
        return highscore;
        elapsedTime = 0;
}

int Game::Run(sf::RenderWindow &window)

i hope you manage to get through it (i think my style is not very good, because i am learning this mostly by myself) if anyone has a simple answer i would be pleased to hear it ;)

nevermind i solved it simply by adding:
                if (paused)
                {
                        clock.restart();
                }

world can be so easy :D

so i will add some stuff to let the pause look like the game is paused and upload it ;)

You can easily improve your code:

split your Game::Run() function into many small functions.

on first look your Game::Run() function could look like this:


Game::Run()
{
//All the following functions could be added to another init() function as well, then you would just write init()
//here instead of flooding the run function with ~5 init functions
initSound();
initBackGround();
initPlayers();
initCounter();
initPoints();

while(running)
{
handleEvent();
if(!pause)
{
update(); //all those time updates you do
draw();    //contains specialicst draw functions for all the stuff you need to draw
}
}
}
}


}

This should be your run() method. Way easier to grasp, maintain and it is more motivating to work with it.


I find it way more relaxing to have many rather small functions then a few giant ones.
Rule of thumb for me is something like "7 lines is great (of course not always doable), max around 40 lines."
Beyond about 40 lines it just becomes a mess and something is most likely wrong.

Hey,

I've been really buisy lately, so I just managed to do a little hotfix regarding to the coop thing.

if you are at the third boss, there is now tracking added for the sec player if the first is dead ;)

Thank you ;)

I thought that I keep you guys updated :D Been really busy recently..
I managed to get the intro to start when the user wants it to. But the project got really spaghetti-like.
Because of that i thought about some changes in the structure. I have no idea of how to make an uml-diagram out of my c++ code, so i painted it :'D. Here is the photo:




For the ones that have no idea of my code, i will put the music into the main.cpp and make one file out of all the IOxxx files. As you can imagine, this will take some time ;)
