New effect function fxAddShadow

[CrosRoad95]

syntax:

bool fxAddShadow ( [ string shadowType, ] Vector3 position, Vector2 offsetA, Vector2 offsetB [, int color = 0x80FFFFFF, float zDistance = 4, bool drawOnWater = false, bool drawOnBuildings = true ] )

Must be used in render function like other dx functions, works better in PreRender ( avoid 1 frame lag )
returns nil if arguments are invalid, or false if limit of up to 48 shadows reach. size of shadow should not be greater than 64x64 units. the more shadows in the larger size, they started to be less precise.

if shadowType skipped, plain color will used
they are small graphical glitches at connetion of triangles

• zDistance - how far below shadow will looking for collision
• drawOnWater - seems to not working properly
• drawOnBuildings - increese amount of objects which supports shadows
• offsetA/B - are defining size of shadow, typicaly -X, 0, 0, X is shadow X units in all 4 direction
• color - if you don't know, back to school

All allowed shadows types are below

Example script:

shadows = {"car", "ped", "heli", "bike", "rcbaron", "explosion", "headlight1", "headlight2", "blood", "headman", "wincrack", "lamp"}

addEventHandler( "onClientPreRender", root, function()
  x,y,z = getElementPosition(localPlayer)
  fxAddShadow(x,y,z, -1, 0, 0, 1, tocolor(255,0,0,128), 10, false, true)
  for i,v in ipairs(shadows)do
    fxAddShadow(v,2331.64697 - i * 2.5, -1658.43030, 13.43058, -1, 0, 0, 1, tocolor(255,255,255,255), 10, false, true)
  end
end)

Screenshots:

"car", "ped", "heli", "bike", "rcbaron", "explosion", "headlight1", "headlight2", "blood", "headman", "wincrack", "lamp" from left to right

drawOnWater may work if you apply a shader to the water which enables depth buffer usage.

technique simple
{
    pass P0
    {
		ZEnable = true;
		ZWriteEnable = true;
		ZFunc = 4;
		DepthBias = 0.000001;
		SlopeScaleDepthBias = 2;
    }
}

i fixed conflicts and i'm waiting for marge

[qaisjp]

Nice work overall, good job. I've left a few comments.

Also some files affect all line endings - please can you fix? If you don't know how, I can try to document instructions when I find the time. Just let me know.

[CrosRoad95]

Make an tutorial how to fix line endings and pin up somewhere future

[CrosRoad95]

fixed again, unteaded due #1122

[qaisjp]

#1122 is resolved, please can you test this? and resolve conversations for the bits above that you've done

[qaisjp]

nice PR. here's some changes for you.

I think this can crash the program. You don't allocate memory for Rw textures using the new operator. You have to use RwTextureCreate. I want to know where you are deleting this texture? It looks like this will cause a memory leak.

[CrosRoad95]

I dont know how properly use wrcreatetexture, and current code doesnt crash

[buepas]

What's the current state of this @CrosRoad95 ?

[CrosRoad95]

after some updates, it starts crashing almost all time

[botder]

The changes seem fine, but you have translation commits in the branch and pull request now.

[CrosRoad95]

updated

[botder]

The changes for the translation files are still there.
