Work a lot on the level editor. I've added edge tiles, but this caused a problem with the level format because the number of tiles is now in the double digits and I was using two digits in the tile maps. The first determined if the tile was drivable or not and the second was the index of each tile. I had to make the tile maps triple digits now because of that.

#gamedev #sfml

I've also allowed the changing of the x coordinate where the player character starts.

Not pictured, but I'm also working on an additional enemy. This one lays mines if the player is behind it.

#gamedev #SFML

Added the mine car. It lays mines when the player is behind it.

If you noticed the lag. The game lags when there are too many cars onscreen. I don't know why. It's a 2D written in C++. I normally create levels where there aren't that many cars at once.

#gamedev #sfml

Now, I'm working on a high score table. I got it to load random scores from a text file and sort them by score using the insertion sort algorithm.

#gamedev #SFML

So, I think I fixed the lag problem, key word being "think". So, in SFML, you have two objects for sounds: sf::SoundBuffer and sf::Sound. The sound buffer just loads the sound file. And sf::Sound is an instance of said sound with a pointer to the buffer. Up until now, I have every game object holding all of the sounds they play in their own sf::Sound objects. I thought it wouldn't be a strain on the memory because the actual sound data is stored in the buffers, but now I have a singleton class to handle all the sound playing.

I've noticed that there is somewhat less lag when there is a clutter of cars, but I haven't truly verified that yet. I haven't done it on a huge cluster of cars. Anyway, this should be a good thing, because the game is piss easy right now with amount of enemies on-screen.

#gamedev #SFML

Okay it doesn't seem like it's fixing the lag. At least it did fix the problem of audio crashing (apparently you can't have more than 140 sf::Sound objects in memory). I will try to fix the problem tomorrow because my adderall is wearing off.

#gamedev #SFML

Maybe it did fix the lag, but only slightly. I've also rearranged some if-statements, which also seemed to help.

Regardless, if you drive slowly enough, eventually all the cars in the level will appear on-screen at once because the only start moving once they are fully onscreen and will only disappear once they are on the bottom of the screen. So you will eventually get lag. But nobody is going to play the game that way so who cares?

Unlike my previous game, enemies do have some sort of AI, as opposed to just having patterns. Naturally, there are a few state machines and lot of if-statements even for this basic AI, but that's also because of poor planning. Some could be turned into switch statements.

Also, having a mine car does increase difficulty, a little bit. So, I probably won't need that much more cars on screen.

Anyway, the game is coming along nicely and quickly regardless. Like the last game, don't expect anything ground-breaking, just something that would be fun for a couple of minutes.

#gamedev #SFML

Added name (initials) entry to the high score table, as in you can change the characters around, but can't save the highscores, yet.

#gamedev #SFML

Oh, I've also replaced one large if-else statement with a switch statement. I think that might help with performance. Contrary to popular belief, a switch statement and an if-else statement do not compile the same way. if-else uses branching instructions (constantly checking for and calculating conditions) while a switch statement uses a lookup table.

#gamedev #SFML

I've added a checkpoint system. Checkpoints have to be added manually in the text file because I haven't put them in the level editor yet.

#gamedev #SFML

Checkpoints have now been implemented in the level editor, but for whatever reason they aren't visible. They do load. I don't know why this is happening. I will probably work on it tomorrow.

#gamedev #SFML

Finally, checkpoints are now visible in the level editor.

#gamedev #SFML

Checkpoints can now be placed and deleted in the level editor. Note that these checkpoints aren't actually visible in game, only in the level editor.

The red part represents where the player will respond. The yellow part represents where the player needs to cross in order to reach it.

#gamedev #SFML

Now creating the second level using my level editor. This one is a desert level.

#gamedev #SFML

Desert level is done. Created a forest level using the level editor.

#gamedev #SFML

Now creating a bridge level.

#gamedev #SFML

I'm realizing that this game is piss easy because Spy Hunter-style enemies can only attack from the side. While I do have a mine car. It isn't enough. Unlike the original Spy Hunter, enemies cannot appear from behind because this game has predefined enemy placement. And if you know where the enemies can attack, you can always attack from behind, and never have to deal with the threat of enemies attacking you.

I plan on adding one more enemy that appears from behind and will shoot you on sight. Hopefully, it will add a little bit more challenge. However, I need to be careful about adding too many enemies on screen because of the lag problem that I can only mitigate so much.

The other option is just to scrap predefined enemy placement altogether, and have cars appear from either the top or bottom after a certain interval with a limit on how many cars can appear on-screen at once. This would obviously be a hard choice because I put so much work in designing the levels and even creating my own level editor, but unexpected turns are just simply a reality in game development.

#gamedev #SFML

Now, I'm experimenting with having randomly spawning enemies as opposed to predefined enemy placement in levels. It should help with the problems I had previously and also allow me to include enemies that appear from behind (which I haven't implemented yet).

I should also tweak the behavior of some enemies. Have them catch up to the player, if they attack from the side.

#gamedev #SFML

Enemies now appear from behind. I still need to tweak the behavior. I'm trying to program them to catch up to the player when they appear from behind but they still behave oddly.

#gamedev #SFML

Created a snow level.

#gamedev #SFML

Working on a farm level now. I even have tiles for both corn and some sort of crop. I tried making an apple tree tile, but it ended up looking weird.

#gamedev #SFML

Player car now spins out if it gets hit by spikes or shot by a limo.

#gamedev #SFML

Working on a credits sequence. It isn't that much because I'm the sole developer and I didn't use that many third-party assets (yet). I decided to add the tools I used to pad it out.

The credits are loaded from a text file with it's own simple markup format.

#gamedev #SFML

Added a sound effect when the player car spins out.

#gamedev #SFML

Wrote a debug level select.

#gamedev #SFML

Made a beach/island/sandbar level. I don't know if I'm going to make more levels. Other than that, I just need to tweak some things, add music, replace the Spy Hunter sprites with my own or stock assets, give this a name, and then I'm done.

I'm hoping that my next game would be something more inspired.

#gamedev #SFML

Added background music. This track is called Mom's Workout CD by Zane Little Music on OpenGameArt.org.

#gamedev #SFML #indiegames #gaming #indie #indiegamedev

Added a toggle between window and fullscreen, which I can't show in my recordings.

#gamedev #SFML

Trying to replace the Spy Hunter assets with my own but I suck at drawing.

This is supposed to be a car.

#gamedev #SFML

Replaced the player car's sprite with my own. It kind of looks weird though. I probably should make a smaller one and have this sprite be for an enemy. It turns black when destroyed because it's supposed to be charred.

I also made this using Piskel instead of Pinta because Pinta, for whatever reason, keeps on randomly crashing, even after updating it.

#gamedev #sfml

I wasn't planning on making anymore levels, but then I realized that Level 1 was basically a vertical slice level, so now I'm making the actual Level 1.

#gamedev #sfml

Still replacing all the Spy Hunter assets with my own. I made the civilian cars look like taxis so it would be easier to recognize them as civilians.

#gamedev #SFML

I now replaced the assets for the spike car and limo. All that's left is the bumper car.

#gamedev #SFML

Created a sprite for the bumper car. Still have the bullets and explosions but I will get to them eventually.

#gamedev #SFML

Replaced the bullet and explosion graphics with my own. The explosion could use a little more detail though.

#gamedev #SFML

Added more detail to the explosion sprites.

#gamedev #SFML

Changed destroyed vehicle sprites from "charred" to wrecked cars like what the original Spy Hunter had. It just looks better since they are usually destroyed by bullets and not explosions.

#gamedev #SFML

So I'm almost done with this project. All I need to do is add a few more songs, sound effects, and iron out a few bugs.

But I have an important question: What should the title be? It's a Spy Hunter clone and it has no story. Unlike my last project, I can't get away with coming up with some made up name because it's set in a realistic setting.
