Animated texture?

[DigitalHax]

Hey,

 

I want to use a corona to draw a texture in 3d. But I want to have it to spin. I am not sure how I should do this, but I know you can have animated sprites. Now I dont know much about image editing, but I think this is the only way. So how can I make an animated sprite?

You can either simply paint a series of textures on to a suitable plane as I have done in the past (very fast) or you could use a shader to do so (never tried but I think someone, possibly Aily, produced one in the past).

What about how you do things like animated explosions like in the explosions topic?

 

Apparently those were animated.

You change the texture continuously... that's animated. 2D animation is just a series of 2D images one after the other. So what Pixel said is just that. There is no single animated image file.

[Pixel Perfect]

correct, well kind of, you can sequence lots of separate image files but most people store a series of images in a single file for convenience ... see this animated sprites link: animated sprites

If you'd like, I can make one for you? ?

 

But I want to have it to spin.

In what way would you like it to spin?

Like, rotating around it's own center?

 

I'm creating all kinds of animated spritesheets, so if needed, I could make a pack with only animated lensflares.

Well I was thinking of having a cool crosshair that spins from the center.

Not sure if this is what you're looking for, but here's a rotating crosshair.

 

[DigitalHax]

Yeah that's the sort of thing im thinking of... Now what was that you were saying about being able to store all in a single file?

[DaDonik]

Well you can animate a texture in two different ways:

 

1) All your animation frames stored in a single texture. That means you create a plane, use PaintEntity() to texture that plane with your texture and write a shader that changes the UV coordinates of your plane every now and then, so it only displays a single frame of your animation.

 

2) All your animation frames stored as seperate textures. Also make a plane and use PaintEntity() to texture it with the first animation frame. After a certain time you call PaintEntity() again, but this time you load the next frame of your animation. That goes on until your animation is finished.

 

From what i read, the second approach seems to be much faster.

 

Edit:

The spinning crosshair could be done using a plane with a crosshair texture and alphablending. All you need to do is to rotate the plane slowly over time. That way there would be no need for multiple textures and it would be faster and less memory consuming.

Leadwerks has no support for gif right?

[DigitalHax]

No.
