| If you guys wanted to simulate sparks caused by bullet imapacts on metal objects such as vehicles etc, would you.... Use an animated sprite / particle sys? Object based particles with gravity? Any other approaches? It's for an FPS, but I guess less is more? Couple the animated sprite with a light source? I am simulating m16's and ak47's |

| Particle for sure with some random spreading so each time bullet collision happen it will not be obvious repeated same animation set.. |
| ||
| Hmmm... Ok...My first thought would be to create say, 10 particles in one pass and then let them randomize and fall etc. Would you light source the initial flash at particle creation? I am thinking of creating a low-glow light (red - yellow) to follow the falling sparks. Would you have the sparks bounce off of the surface they strike? Too many options! :) |
| ||
I just thought of this, couldn't you take the X Y and Z velocity of the object just as it hits another object, then move the particles likeMoveEntity Particle,-X,-Y,-Z to move them the opposite way that the object was moving? |
| ||
| Try those options and select the one which pleases you the most. |

| I'd rather try what pleases others first; I have been looking at my code for 4 years now....I am tainted! :) You know, you make a nice graphic/texture or object. It 'wows' you for a day or so....you show your non-interested wife / husband / dog / cat ....and they say "Ummmm yeah, that looks err...cool" [yep, my pets can speak] After a while, it just looks like stuff....and this community scares me; PPL cant even place a gun in the left hand without 100 posts telling him "it's not the way to do it!!!" Anyhow, I will try the easiest: Sprite based method to see if the effect is appropriate, but will need to look at actual particles that react with the terrain / walls etc. I have other requirments within my game that require non-sprite particles (rock debris / falling leaves / birds / fish) @ Green Fire Good idea, I used this with my grenades as they bounce off of the terrain. (if the Greande heads at a 45 degree angle when it hits the ground, it loses 1/3 of its forward speed due to friction. it flips the fall angle 45 deg to -45 and then takes off a 1/3 Works ok. Not 'great' physics, but effective. |

| Just watch out with particles as if you have a rapid firing gun, it may produce too many particles and slow your game down. Have a limit on the number of onscreen particles, or spark particles and stop producing them if that limit is exceeded. |
| ||
| Yeah. Thats my major concern. I have a whole lot going on as it is- and I think im near the limit. (no object based LOD atm) |
| ||
| I do that effect with Particle Candy. I just put the particle emitter where the bullet hits. You can see what I am doing by downloading the alpha build of Hover Cube. If you shoot a green target cube then you get a small explosion with green particles that shoot off. Download is in my sig. There are some screenshots in the Blitz Showcase. |
