transparency, or GLOW FX from a Photoshop layer to a Corona sprite.

#1

hello,

I’m making a side scroller Zombie game.

How do I retain the transparency, or GLOW FX from a Photoshop layer to a Corona sprite. it seems that particle candy can do this–why do I have trouble when exporting a PNG from PS?

I’m trying to make laser blasts, explosions, lightning FX and a glow shield, and all I get are hard edges.

I’m using an alpha channel with anti alias, but it doesn’t match the photoshop layer I created.

Pleas email me at

and I’ll send you a file or jpg so i can show you what I mean.

getting frustrated.

thanks

Experiment with the additive blendmode. Do something like this:

glowImage.blendMode = “add”

Or something like that. [import]uid: 70134 topic_id: 29075 reply_id: 116979[/import]

Are you saving as 8 bit pings or 24 bit (32 bit in Corona terms, 24 bit in Photoshop terms)? 8 bit will clip your glows pretty badly, but saving as a 24 bit with transparency works really well. [import]uid: 19626 topic_id: 29075 reply_id: 116999[/import]

I’m pretty sure it’s 32 bit. I have a 300 dpi PS cs3 layered file open. I’ve saved as a PNG and I don’t think this works. I’ve tried saving with Alpha channel but that is really only an on/off option. I need a soft edge on many of my game elements (lasers, fireballs, fire, explosions, lightning, zombie brain bits, etc.) How do I keep this soft edge in PS and import into Corona.

I don’t need to save with Alpha Channel do i?

Thanks

This gives a glow to any solid image? can I color the glow? [import]uid: 131481 topic_id: 29075 reply_id: 117421[/import]

I do a Save for Web or Devices and choose PNG-24, Transparency Checked, Save as sRGB checked.

I’m a GIMP user not a photoshop user so what I’m about to say may be totally wrong. I recall when I was using Blender 3D to render sprites there were 2 options for colorspace in the render panel, rgb and rgba. IWith just rpg saving as a png no alpha was used and I had hard edges. With rgba I had alpha transparency. Maybe there is a similar option in photoshop? Again, I may be totally wrong. [import]uid: 164950 topic_id: 29075 reply_id: 117434[/import]
