enemies shooting

[Jam0864]

I'm trying to make enemies shoot it all works (i followed a instruction thing i found on this site)except the sprite that shoots is going behind the trigger so you can't see the enemy and you see a trigger in front of him it still shoots just it doesn't look very good because of this

I just found out EVERY sprite goes behind the trigger including the player

The sprite is the transparent color right?

I don't think an entirely transparent trigger would work because collision detection is based on non-transparent pixels.  However, you could try making the trigger less visible -- could you just make it 1 pixel?

oh yah....
ugh...*think real hard*
I thought there was a way to fix that...ugg...
arg...a good song just came on now I can't think...
so I guess this 100% useless post is over...

It is one pixel different than the background colour but rest of it that is the background colour goes around it and completely covers the shooter

[bluemonkmn]

It shouldn't be the background color; it should be the transparent color.  Then it couldn't cover anything.

You may be confused by my explanation in the Enemy Shooting tutorial.  Let me explain perhaps more visually.  You will need a single-pixel trigger sprite.  that is, create a tileset that has 1x1 tiles, or maybe 3x3 and fill in the center pixel, if you want to make it a little easier.  This sprite should be the trigger.  If you are using larger tiles, i.e. 32x32 graphics and only filling in one color, then problems can arise like you've seen if you don't quite know how transparency works for sprites.

Just create an insignificantly small sprite.

I can't get transperensy to work but the 1 pixel sprite idea works thanks

[Jam0864]

How do you do transperency i've tried using paste + i can't get it to work

[bluemonkmn]

The color that a sprite uses as the "transparent" color is determined by the color of the top-left pixel in the tileset (the top-left pixel of the first tile in the tileset).  Any other areas using that exact same color will show as transparent.

[durnurd]

I thought the transparent color for a sprite was the color in each of the four corners of the specific frame, and the transparent color for a tileset (when used as tiles on a map) was the top-left pixel

[bluemonkmn]

Nope, the only difference in transparency between tiles and sprites is that tiles can be drawn opaquely if the layer is not specified as transparent.  Sprites are always drawn with a transparency color determined by the top left pixel of the tileset.
