I want to create smoke effect like this

[tipforeveryone]

Hi everyone,

I found this video on youtube, do you see the smoke effect when bullet hit ground, it looks awesome.
Anyone has any idea how to make one ?

You can make smoke in the editor using particles. I made smoke and fire by just playing around with property values. It came right in the end.

I made my smoke using particles too, it looks great but im not satisfied after watching the video, sothat I ask for ideas to how to create the same one as video.

This smoke is so different

You can also literally draw out anything you want with animated sprites.  That's how many of the effects in popular games are done (like hit, magic, etc.).  For example, a guy here talks about how he did effects for League of Legends:

Thanks, I will give this a try

You need to simulate smoke in Blender or somewhere else and render it into a sprite sheet.

Yes, the reason it looks good the particles are using an animation of smoke spreading. We support this, but you need to come up with the artwork.

thats a good video .. but how can i control the pictures in a sprite sheet? the spritesheet shader like the "firepit" shader from shadmar starts random in the individual pictures of a sprite sheets. In the case of fire this is not a problem, with explosions or with Gun Effects it should begin however with the first picture. I have such a spritesheet (muzzleflash .. a bullet and smokes but it does not start on the first picture. And creating an effect with maybe 20 seperatly bictures is a bit exhausting (I hope you understand my english )

[gamecreator]

Does the firepit really start random (I don't know)?  If it does, it seems like that could be changed in the shader code.  Beyond that, there is probably a program or two out there that helps with animating things like this and batch exporting individual frames for you.  I believe you can also copy pixels from one texture to another so you can also separate a sprite sheet into multiple textures that way.

mhm or the problem is because we create the sprite and hide it .. so the material on the sprite is set and run the spritesheet pictures in the backround .. if i now show the sprite and at this moment the 4th picture is displayed, then it looks bad

[burgelkat]

ok something like this .. (its not perfekt)

You can set the number of animation cycles:
https://www.leadwerks.com/learn?page=API-Reference_Object_Entity_Emitter_SetAnimationCycles

I think it will start at frame 0 if only one cycle is set but I am not sure. If that is not the case then I will change that to be the default behavior.

This is what I made today with you guys's suggestion, It looks quite right. What do you think ?

ok looks with that nice. at the moment only single-shot looks good .. i have to build a spritesheet without a bullet shell

 

so thats my solution for the moment

 

FPSGun.lua

@burgelkat you should make the particle start off small and grow, and the fade-in takes too long. That might be your animation or it might be your alpha curve.

[tipforeveryone]

Wow what a long code content haha, this may make this topic really hard to read, can you attach a text file instead ?

[burgelkat]

Here the sprite sheet if someone will use it

 

thx josh will try your hints

[tipforeveryone]

Finally

 

[Josh]

Looks fantastic!

[Thirsty Panther]

Nice.

Also has a massive magazine

Any chance I could be pointed to any more details on Leadwerks and sprite sheets?
