Play with the affectors and change images...

Create these three folders inside a main folder:
texture, scripts, material.

Needs images named: smoke.png and ring_flare.png

Next save each of the scripts below to the scripts folder:

thanks DK_PETER, you are the particles master. the after explosion wind are more exact than the start. it is like a violent sand storm. also when we move the camera to position 1000 the scene are more dramatic
line 23: MoveCamera(0, 0, 1, 1000)
i have manipulated your smoke.png almost randomly and i got this:

it gives scary sense
also i have tried this

Hi applePi

Yes..You're right. Moving the camera way back enhances the effect.

I've messed with the nuclear bomb idea a bit more without scripting and came up this small animated demo.
Sorry for the messy code. This was made in a jiffy.

a.jpg, b.jpg, b2.jpg, c.jpg, sun.jpg, ring_flare.png, smoke.png
Images for download here: http://www.purebasic.fr/english/viewtop ... 36&t=62324

Here's the demo code: (Have fun).

(Code edited 12:28)
Added a more fiery bloom and fireblast. It could use two particleemitters more to make the bloom 'fold in' on itself.

very cool code DK_PETER , a movie using programming code !!. who have not tried it yet will miss many goodies. can be used in a science exhibition, to demonstrate the hazards of nuclear weapons. the flocking birds particles are great. it gives the illusion that they are really a groggy flying birds even they are tiny circles.
i should say also that the paper particles in the fire cracker demo also deserve attention since it is suitable for making a tornado , you may want someday to simulate a tornado or whats called : dust devil:
https://www.youtube.com/watch?v=Mo8561rS13E
https://www.youtube.com/watch?v=EpYDzdI5PMU
i have played with the fire cracker in a low gravity and have used a circle equation for the particles but still not satisfied , i have posted before a tornado example http://purebasic.fr/english/viewtopic.p ... do#p436120 but it does not resemble a real tornado or dust devil at all

Hi applePi.

Simulating a dustdevil/tornado is not easy, but here's my first attempt using particles.
It needs some finetuning, but it's certainly doable.

(Edit: Added simple debree to the dustdevil/tornado)

thats very great DK_PETER ; but because the plane are distinguished and contains other ideas such as how to assemble a model using nodes it deserve a new thread alone , for the future users can find it easily.

good you have not used separated material files for the devil dust. wish Comtois add more material functions for easy using the engine . also we can beautifying the devil dust by moving the cam far away. i have played with your code and do MoveParticleEmitter in a small orbit. and choosing the particle size 2.
DK_PETER code with the above slight testing (as said needs some pictures above in folder "texture"
