missile sprite

[STGraves]

Hello I would like to know, can I add a sprite to a missile, kind of like making the missile look like a face instead of a projectile.

Thanks.

A missile is just a solid rectangle. Only the width, height, and color can be changed. Sprite data cannot be applied to a missile.

You'd have to take a sprite and treat it like a missile.

..like this

 

set kernel_options player1colors playercolors pfcolors
set tv ntsc

begin

if joy0fire then goto ready

player0y=50

..this is a little demo called Ghost Missile that gives you color for both sprites and a missile that is another graphic of your player0 sprite. (It also gives a little background animation..)

 

GhostMissile.bin ..or download it just to play around!

Using the missiles (and ball) as a sprite is possible, but it's an advanced technique that would require you to switch to 6507 assembly to use. Some examples:

 

In Hunchy II all bells are drawn with missile0, the blue "bullets" you need to avoid are missile1

 

In Dark Cavern a number of the enemy are drawn with the missiles:

 

In Super Challenge Football, most of the players are drawn with the missiles.

 

You can use Stella's Fixed Debug Color Mode to see which elements are drawn with which object:

 

See this reply for more info about debug color mode.

But, you probably aren't going to be using assembly, so there are 'other' ways!!

Plus, you said you wanted multicolored sprites, so that would look better than most of those exampled games..

 

Here's the demo WITH a multicolored player0 'sprite' missile..

 

GhostMissile2.bin

 

I will probably use this code to make another game, as I wrote it in about a half hour today in between feeding a 4 month old and napping a 1 1/2 year old..

 

I would use the score counter to change animated backgrounds, widen the movement field but utilize playfield collisions. I would add an explosion animation for player0 and player1, a life counter, and a bunch of different badguys!!

 

If you're gonna use assembly, though..more power to ya!!

 

I was under the impression you were just learning basic and Bb, so assembly might be a bit down the road yet!?!

 

I LOVE Batari Basic!!

Thanks papa for your reply, I will try to add it to my game, thanks again.

After all this time I tried again to add it to the newest version of my game, but it turns out it's not possible, because I'm already using the two sprites provided by batari basic, player0 and player1 I read that there is a way to add more sprites but using the multi sprite kernel makes the classic kernel useless, or at least that's what I'm aware of, I tried using both but couldn't be done, also it's impossible to use pfclear on the code, and my game NEEDS it, it is necessary to reset the playfield otherwise I get bugs on it all the time
