Looks good.

Did you make the spritesheet shader or buy it off just_in_case ?

Robo, i write all by myself, never use any code from other user i think thats good way to improve my coding level (cuz im not programmer)

You should sell it on itchio then if it works well - ie you just input number vertically and horizontally and it gets the texture number you want from that....I will buy it off you if its not too expensive (like $1-2 or something like that).

Default animated textures in CC are a pain to have to split up a from a sprite sheet and then load each image into CC - its slower and less performance than just having a single texture....

post the link below if you could...cheers.

Robo, there nothing to sell, in "before first drawing do something" execute js:


function shader(x,y,x1,y1){
	ccbSetSceneNodeProperty(ccbGetCurrentNode(),"Visible",true);
	var vertexShader = 
	"float4x4 mWorldViewProj;  \n" + 
	"float4x4 mInvWorld;  \n" + 
	"float4x4 mTransWorld;  \n" + 
	"struct VS_OUTPUT  \n" + 
	"{  \n" + 
	"	float4 Position   : POSITION;  \n" + 
	"	float4 Diffuse    : COLOR0;  \n" + 
	"	float2 TexCoord   : TEXCOORD0;  \n" + 
	"};  \n" + 
	"VS_OUTPUT main      ( in float4 vPosition : POSITION,	\n" + 
	"                      in float3 vNormal   : NORMAL,  \n" + 
	"                      float2 texCoord     : TEXCOORD0 ) \n" + 
	"{  \n" + 
	"	VS_OUTPUT Output;  \n" + 
	"	Output.Position = mul(vPosition, mWorldViewProj);  \n" + 
	"	Output.Diffuse = float4(1.0, 1.0, 1.0, 1.0);  \n" + 
	"	Output.TexCoord = texCoord;  \n" + 
	"	return Output;  \n" + 
	"}  ";
	var fragmentShader = 
	"struct PS_OUTPUT  \n" + 
	"{  \n" + 
	"    float4 RGBColor : COLOR0;  \n" +	
	"};  \n" +
	"sampler2D tex0;  \n" +
	"PS_OUTPUT main( float2 TexCoord : TEXCOORD0,  \n" +
	"                float4 Position : POSITION,  \n" +
	"                float4 Diffuse  : COLOR0 )  \n" +
	"{  \n" +
	"	PS_OUTPUT Output;  \n" +
	"	TexCoord.y = (TexCoord.y+"+y1+")/"+y+";  \n"+
	"	TexCoord.x = (TexCoord.x+"+x1+")/"+x+";  \n"+
	"	float4 col = tex2D( tex0, TexCoord);  \n" + 
	"	Output.RGBColor = Diffuse * col;  \n" + 
	"	Output.RGBColor *= 1.0;  \n" +
	"	return Output;  \n" +
	"}";
	var newMaterial = ccbCreateMaterial(vertexShader, fragmentShader, 0, null);
	ccbSetSceneNodeMaterialProperty(ccbGetCurrentNode(), 0, "Type", newMaterial);
}

and call shader(x_length,y_length,x_frame,y_frame) inside of "every few seconds do something" (x_frame and y_frame is yor frame so you can call this part of image in any way you want)

Very cool 'samgrady' - thanks for that.
I haven't had much time for shaders of late - it worked !

Step 1 - I just created some global variables on first load:

var partX = 0;
var partY = 0;
var maxX = 4; // horizontal images
var maxY = 4; // vertical images

Step 2 - then just ran this little bit of code every 100ms:

if (partX == maxX) {
partX = 0;
partY += 1;
if (partY == maxY) {partY = 0;
}}

shader(maxX, maxY, partX, partY);
partX += 1;

and badda boom !! - she's a goer !!
I also just changed line 42 from 0 to 13 for transparent...

Cheers !
