I've been working on a huge FPS project, which I've named "Penguin Warz". I've gotten a lot done, and I've managed to have a lot of features I haven't seen in other game before. However, I am having many problems with the engine. Rather than get into specifics, I figured I'd just upload the .gmk file. So here is the link to it. If you open up the game information, you'll find all of the known problems and all the features I want to add. Thanks for your help in advance.

[Crhonos]

You could post here some of your problems. Don't expect people to download your file to see what you want.

[Ecorp99]

There are lots of problems, but as you suggest, I will. Here they are, straight from the game information.

Current Problems
Screen animations don't play. 7
Turret guns fire animations don't play. 7
No sound for hitting a turret gun. (easy fix, no internet) 1
No friction in backwards movement. 10 (might not be fixable)
Bullet holes don't show up. 6
Friendly NPCs shooting animation doesn't play. 7
Crouching can be smoother. 4
When you call one penguin and then go near another one, it follows you too, then when you stop them, they all stop and no longer move. 7
Projectiles don't change Z when player does. (not sure if player changes Z either) 10
Floors are acting funny. All except snow floor. 10
Achievement system works, but displaying the achievements doesn't. 8
Vehicles are dispayed funny. 10
Exploded bodies are small. 7
Scrolling acts funny 8

Uhh, you can't expect the internet to fix every issue in your game for you for no return. You would be better off asking for help with specific programming problems, describing what you are trying to do, what you have tried (including code) and how it doesn't work. Most of your problems seem to be more suited to the Q&A forum too.

A set of bugs that big all of a sudden ? In future fix a bug when you notice one, don't just leave it behind.

I get the impression that you're dealing with a huge engine even you don't know how or why it works, if it even does. Why'd you think anyone here would want to dig through such engine if you don't?

Pick one problem at a time and post the relevant pieces of code, then you're much likely to gain answers.

[Ecorp99]

@Nehacoo Ok, I'm trying to create a professional looking game in Game Maker, and make an engine that other people can use to make their own professional looking games. I don't expect the internet to solve my problems for me, I just want advice and help on how I can fix the problems I'm having, and I apologize if I made it seem like other wise. I can't post codes that I have tried and don't work because a lot of these bugs are old that I couldn't fix and waited to fix until later. I have also tried many different codes, and the bugs that are left are one's that I couldn't think of a way to fix them or anything that I tried failed horribly.

@Tepi As I said above, most if not all of these bugs are ones that I either couldn't fix at all or that I couldn't come up with a way to fix them. About the engine, about 98% of the engine is my own coding. This engine was built off of an engine I found entitled "Fps 6.1" which was an extension to the original FPS tutorial. I understand all of it that I coded and almost all of what I didn't. As for the relevant codes for individual problems, I had thought about doing that but I figured putting up the engine would be easier, but as you wish.

Crouching Problem (not so much a problem, but it's annoying and I'm not sure how to implement it)

Penguin NPC Following Problem

if distance_to_object(instance_nearest(x,y,obj_penguin))<24
{
//Code needs work
if (instance_nearest(x,y,obj_penguin))obj_penguin.follow=false
{

}

if (instance_nearest(x,y,obj_penguin))obj_penguin.follow=true
{
with (instance_nearest(x,y,obj_penguin))obj_penguin.follow=false
}

The penguin NPCs behave according to their variable "follow". As I said above, all penguins react when you try to command just one. They also don't behave normally (their supposed to attack enemies) if you set them back to normal (meaning they don't follow you).

Player Z Problems
I just found out while looking through the code that I found a solution, I just haven't done it yet. My bad.

Floor Problem
I think that this is a problem with Game Maker. It's a normal script that works with one floor, but all the other floors are switched with different textures, some of them that don't even really exist. I'm not sure what's wrong.

Vehicle Problem
This one is like the floor problem. Not sure what causes it, but they come out as big red boxes.

Small Exploded Body Problem
Not sure about this one either. I have two different results for an enemy dying, controlled by variables. When an enemy is killed by an explosive, it creates a set of gibs in preset distances around (hoping to change that soon) and the body part is small.

Scrolling Problem
I have a system that allows you to change weapons by scrolling the mouse wheel, but sometimes it jumps around randomly for some reason.

I'm aking a first person shooter, and I need advice. I have only made simple games so far, and I want to make something better. if you have any advice, please let me know.

Uh, wrong place for this, but I'll be kind and PM you what little advice I have

[Ecorp99]

This is still active. I still need any and all help I can get. Oh, and if anyone knows a good, easy to use model making program that would be great to know also.

[slayer 64]

i'm just gonna guess that the best thing to would be start over. start from scratch and copy over the useful stuff, either with cut n paste or the built in resource import/export feature.

but from the code i glanced at, you need to get better at writing and structuring your code. big projects really need it. small projects you can screw off and be redundant.

this code for example

if distance_to_object(instance_nearest(x,y,obj_penguin))<24
{
    if (instance_nearest(x,y,obj_penguin))obj_penguin.follow=false
    {
        with (instance_nearest(x,y,obj_penguin))obj_penguin.follow=true
    }
    
    if (instance_nearest(x,y,obj_penguin))obj_penguin.follow=true
    {
        with (instance_nearest(x,y,obj_penguin))obj_penguin.follow=false
    }
}

can be shortened. all the other code can be shortened and made easier to work with too.

with instance_nearest(x,y,obj_penduin)
{
    if distance_to_object(other)<24 follow=!follow
}

[Fishman1175]

Oh, and if anyone knows a good, easy to use model making program that would be great to know also.

I can recommend model creater v5. It has served me (and others) very well for GM purposes.
