Invisible colour

[Klomster]

Greetings.

I am making a small mod that features adeptus mechanicus from warhammer 40'000.
Perhaps not fitting, but i don't care.

Here are the problems i have run into, and with a bit of help from you, wan't to fix.

What colour should i use too create invisibility?

I've tried white, black, i've used no background in photoshop, nothing works.
Is it a specific rgb colour i need to use?


And i am also troubled with the fact that one of my weapons doesn't work.
Namely the earthshaker artillery cannon (i know, overkill on the poor fantasy guys but i wanted to do this mod)

Code: #newweapon 603#name "Earthshaker"#rcost 50#dmg 200#att 4#len 5#nratt -3#sound 18#armorpiercing#twohanded#range 150#ammo 12#aoe 50#nostr#secondaryeffect 171#explspr 10113#flyspr 100 1


It doesn't show the explosion effect i told it too have and it isn't aoe as i also told it too be.

Theese are the main problems, hope i get answers.

Basilisk mod stats.

Theese are the artillery unit codes, weapon and unit. Some things are unbalanced but that is a later issue.

Like (for some reason, the mod file is correct) skitarii troops (infantry) have 1000 castle defense each instead of 2. I'm working on fixing that.

Try magenta for the invisible colour. I don't know the exact RGB values, sadly.

But... other mods use it, so look at one of their tga files.

For the cannon, should #nratt -3 be #nratt 3, perhaps?

[Calchet]

Pure black (0,0,0) will be transparent for images saved as 24-bit tga.

Magenta is not invisible color, it's shadow. Its RGB is (255,0,255). Black is supposed to be the invisible color, and it's got to be the full (0,0,0) black.

AoE 50 might be too big for the weapon. Try with lower AoE first, and see if that resolves the problem with explosion sprite. AoE 5 should work, and then increase it by 10 until it stops working.

You can get higher effective AoE by increasing number of effects.

The funny thing is, in most old games or console games that use simple alphas like this, magenta is the usual color to indicate transparency, because it's usually safe to assume that it won't see any actual use. Only Dominions is different!

On the other hand it makes sprite pages much easier to look at because they're on a black background with a magenta shadow, as opposed to a magenta background with a black shadow. I know which I prefer for seeing the actual details of a unit.

Another couple of issues with using black as the alpha colour:

1. Black is a common colour so artist will need to be mindful that instead of selecting black, then need to change the colour slightly. This is an issue in graphic programs where artists are used to working from palettes.

2. Artists are also used drawing with soft brushes rather than pixel pencils so there is usually an anti-alias rim around the outside of images. When these images are used in-game there is a black rim of pixels around the edge where the anti-alias has kicked in. There are ways around this but by having magenta as the bg colour the problem areas should be a little clearer. Best bet would be to use a neutral warm grey (similar to the battle-field backgrounds) for image construction, then change the base colour afterwards. That way the aliasing is with a complimentary colour, I guess.

Of course, if we could use 32 bit TGA files instead of 24 bit, there wouldn't be a problem (32 bit supports full transparency).

[Klomster]

Aha, slight miss there.

It's supposed to be 24 bits.

Check, i'll change the targas to 24 bit files instead of 32 bits.


I first started out with 5-7 aoe for the weapon, but it didn't work.

The explosion effect didn't work either.

[Klomster]

Haha, awesome, now the models look good.

And i added a new "Pretender god"

Lucius pattern warhound titan. A really hard warmachine that destroys all in its path.

Only problem is that when i playtest the mod now it crashes when i press next turn (more precisely, when calculating events) and then i get.

"Error, bad monres"

I tried changing the resistances, but apart from that i have no clue what's wrong.
