My first steps into making Intv GFXs

Recommended Posts

Thanks guys for the sweet comments! :)

 

The game have a total of exactly 100 different screens

The premise is you've been captured by a tribe during your adventure and have been made prisoner

You've to escape from their temple without having any weapons/defense

But you'll have to find at least 100 diamonds to open the sacred door to freedom

I tried pressing the button, but nothing happened :)

Also, couldn't help but notice....2015?

Yeah, I'm confident to get the game released by the end of the year

But I'm not gonna rush the development either

So it can be possible it only get release early next year

As cool as it looks, I'm in no hurry and would prefer a delayed yet more polished release.

Yep, exactly

 

I'm actually polishing the game now, there's not much left to do though

as I already pushed the graphics to INtv' limitations to be honest

 

Now, I'm wondering if I should try to make a few cutscenes.....

Here's the Titlescreen

 

Wow! I don't think we've seen anything like that on the Inty. Very sweet.

I love cut-scenes. Not sure why. They were always something that made me want to play better to get to see the next one.

I think that's the point. To me they were always the "prize" you got for advancing through the game. This was especially true in arcade games, since they game-play is otherwise devoid of any story or depth.

Bingo. Avid gamblers know these as "bonuses" in video slots.

 

It's actually why I play them. They have a very similar risk-reward curve to early arcade games. A lot more expensive to play, mind you.

Cut scenes are very time consuming to code if they are complex. This one from Rocketeer took well over 50 hours of coding time alone :-

The intro sequence and cut scenes in my version of Hover Bovver took quite a few 10s of hours too :-

 

 

From what DZ-Jay has said about "Carol vs" he took the approach of a scripted animation engine for the ones in his game. With hindsight, I should have gone down that route instead of doing it the brute force way.

Geez!!!

Now, that's ALOT of coding for sure!

Looks awesome!

 

 

Mine is a simple static screen

the game will already be big enough I guess

Thanks for the compliment. They were fun to do because the player will see them plenty of times when they play the games.

Even animated static screens are pretty neat too. I think a comic style intro sequence would work well on an adventure/exploring game such as.Sacred Tribe.

Yup, I created a scripting engine I called "Auto-Pilot" which operates on each sprite, giving them the ability to move autonomously, following a pre-determined script. Originally, the intention was to move a sprite from one side to the other, pause, then move out (like the first few cut-scenes in Christmas Carol).

 

It turned out to be so flexible, that it was very easy to extend the engine to support additional commands. One problem I encountered was precisely that it was intended to operate on sprites. In a sense, using it for cut-scenes was actually a "hack." However, once I added commands for "Gosub" (call another script and continue when done), "Delay" (to wait an arbitrary number of milliseconds), "Exec" (to execute an external procedure and return when it's done), and "ExecDelay" (to wait some time before executing an external procedure); it gave me the ability to do absolutely anything!

 

Scripts are defined as a table with a series of command calls. Each entry has a command followed by two optional arguments. I typically include all the individual sprite's scripts for a single cut-scene within the same script file. However, each one is executed asynchronously, and triggered independently.

 

Here's a very simple script for the first cut-scene. It sets the elf speed to 27 FPS and moves it to screen column 19 (the right edge of the scene). At the end, it calls the routine "ElfEnd," which essentially triggers the Ghost's script.

 

The Ghost then becomes visible (he was hiding in screen column 1 all along), sets its speed to 42 FPS, and moves it to screen column 11 (about the center of the screen); where it stops, looks around, faces to the right, and moves out of the screen (column 19) at an accelerated pace.

Here's a more elaborate and complex one for the final cut-scene introducing the "Boss". Notice the use (or abuse!) of "ExecDelay." It basically turns the "sprite-oriented" scripting engine into a "wait-and-exec" script which calls many small functions to handle scenery and sprite interactions.

Besides the "Auto-Pilot" scripting engine, there is also an entire infrastructure dedicated to supporting the cut-scenes in Christmas Carol. It includes routines that automatically handle background tasks that add to the polish of the final game.

 

For example, one such routines randomly picks a horizontal position in the stage in which to animate a falling droplet from the roof. It executes after a randomly chosen delay, and it randomly picks between two or three different animation sequences. The final effect is that of droplets randomly falling from the roof, at varying intervals.

 

Another one is the automatic "gate cover" on the edges of the scene. There are "ice cube" blocks at the edges of the scene, but they are transparent. The sprites enter and leave the scene by coming out and going into these blocks, but since they are transparent, the transition looks awkward. My solution was to dedicate a single MOB of high priority to "cover" the blocks.

 

However, I didn't want to be bothered with the direction the sprites were moving and keeping track which block needs to be covered at any time, so I built a routine that automatically detects the closest moving sprite to a wall, and relocates the "cover" accordingly. The limitation is that only one sprite can go in or out of the scene at a give time, but in practice this was not really a problem.

 

Here's a test of how it works:

post-27318-0-89030900-1447274141_thumb.gif

 

Notice that the default location is on the left block, but that a change is triggered whenever a sprite gets close to one of the edges. Again, this is all automatic, and happens during the introduction sequence engine without having to explicitly invoke it.

 

Of course, if I were to do this again (and I will!), there are many things I would change to make it easier and more intuitive. However, as my game attest, it was very effective. :)

OT: Is there any way we can get an mp3 of some of those Carol sound effects? I'd like to make a new ring tone and text message alert sounds..

The sound effect when it says "Ready? Go!" would be a cool text notification. The whoosh sound reminds me of an 8bit equivalent of similar sounds in Zombies Ate My Neighbors on Genesis :)

You can find a lot of them here, including the "whoosh!" sound fx:
