NEW MAP: Hotstepper (lava map for anyone)

[Beherith]

sup guize

maek

Code: Select all

 local s = 2+math.sin (SYNCED.frame/50)/10

into

Code: Select all

local s = 5+math.sin (SYNCED.frame/50)/10

for better rez on a map that big.

[Beherith]

Knorke must see this undulating lava:

[knorke]

@Beherith
no lava visible and no commanders spawn:

[f=0000000] error = 2, LuaRules/draw.lua, error = 2, LuaGadgets/gadgets.lua, [string "LuaRules/Gadgets/lava.lua"]:133: attempt to call field 'CreateShader' (a nil value)

Also while anybody can of course use this for his own maps please dont make "hotstepper_v2". If you want to mark a fork (ie to show something) call it hotstepper_Beheriths_shader" or something, thanks

[Beherith]

Sorry about the misleading naming.
What gpu do you have? Does it support GLSL?

[bobthedinosaur]

MMMMm giant lasagna!

[knorke]

nvidia 6800
from googling it seems GLSL should be supported.

[Google_Frog]

Looks nice. Have to tried Spring.SetMapSquareTerrainType to prevent units wandering into the lava? It might not be as slow as you think.

[abma]

next time, can you please upload it to springfiles.com, so lobbies can download it?

i already uploaded it:

[knorke]

didnt think people would actually start playing this...was just for test

[Forboding Angel]

Behe, that is fucking sweet

the things it needs are:

some sort of steam effect where the lava edge meets with land
a firey ceg when an object enters the lava

[Beherith]

Thanks forb, I dont know lua well enough to do smoke or fire, and I guess that doing it with cegs may be too resource intensive. This current implementation is nearly free, I also added normal mapping to it since.

[BaNa]

the v2 lava looks very nice! we are getting places with this concept!

@knorke:

uh, then sorry. for a "test" map it is awesome! :)

[MidKnight]

Behe, that is fucking sweet

steam might be expensive.
...maybe we can ask the engine devs for an API hook into whatever is used to make that sweet bumpwater-shorewave goodness? (This is 100% uneducated babbling, here).

For a firey CEG, you can use ZK's Units on Fire widget.

[knorke]

i had ceg for lava death but iirc if the ceg was visible only in LOS, then you would never see it (as the unit was dead) and otherwise you could tell where enemies died.

where the lava edge meets with land

thats tricky to find out in cpu friendly way.

Beherith, can you make the shader fall back to normal if gfx card/drivers does not support it? but then looking at it there seems to be such switch already..?

@knorke:
uh, then sorry. for a "test" map it is awesome! :)

its also awesome to watch people not believe there will be lava and then die. superlol to watch games.

[CarRepairer]

Please add spicy lava sauce to my map pizzatime.

[BoSTGI]

knorke i can use this gadget in other map?
because i posted a test map with this code..

if i cant do that tell me i remove the gadget.

thx

[knorke]

BoSTGI:
YES! of course everybody can use it for his maps, my map is just a demo.
Just add a link to this thread (like BoSTGI did) so other mappers can also read up on the gadget.

this map i guess?
Played an older version of the map in a TechA game btw.

Noticed you added more detailed warnings, good idea.
But this:

Code: Select all

	if (tideRhym[tideIndex].targetLevel == 60) and 
           ((lavaLevel - tideRhym[tideIndex].targetLevel) > (tideRhym[tideIndex-1].targetLevel - tideRhym[tideIndex].targetLevel)) and
           ((lavaLevel - tideRhym[tideIndex].targetLevel) < (tideRhym[tideIndex-1].targetLevel - tideRhym[tideIndex].targetLevel) + 1 + tideRhym[tideIndex].speed) then
		Spring.Echo ("LAVA in MIDDLE!")
	end

is a bad way to do it because now you have dozen of code lines just to output some warnings because such a block is needed for each lava tide. Another problem is the
if (tideRhym[tideIndex].targetLevel == 60)
Now if you want to adjust the level of this tide, you have to do so in two places: At the top in the addTideRhym () and in the place where you display the warning message. Easy to lose track of such things.
Generally if you need lots of c&p there is a simpler solution

A better way to do would be a fourth parameter like this:
function addTideRhym (targetLevel, speed, remainTime, warningText)

And then for display do
Spring.Echo (tideRhym[tideIndex].warningText) )
so it could be used like
addTideRhym (300, 0.1, 60, "Danger: High Flood coming in!")

Not 100% what you wanted to do with the long formula but if you wanted to know if lava is going up or down you can just do:
if (lavaGrow > 0) then Spring.Echo ("lava raising") else Spring.Echo ("lava sinking") end

CarRepairer:
arent you old enough to make your own pizza?

[Beherith]

Here is the GLSL version of the shader (with working fallback to normal gl, some glow effects, undulation and darker lava where it meets land.)
Needs heightmap to be supplied with map.

Needs heightmap to be supplied with map.

What do you mean?
