I want to make an animation where a plane shoots many bullets at another one. I don't want to create all bullets and make them invisible since that will make the window laggy and increase render time to near infinity. I want a bullet to not exist until a specific point and then at a specific frame it exists and then at another frame it's nonexistent again.

I couldn't try anything since nobody ever had a tutorial on this.

    Hello, could you add a little more information about your setup, what you have so far, what you have tried, why you think your solution will make your window laggy,... ? – Gorgious Jul 19 '21 at 19:34
  • If you create instances of one bullet instead of making them all single unrelated objects, then the system load won't be that high. – Gordon Brinkmann Jul 20 '21 at 09:55

You should try out a particle system... On the target aircraft, attach a Force that is negative (like -20,000). You can create a prototype bullet and in the Particle Rendering, Render as OBJECT, with your prototype object selected as the instance object. In Field Weights, you might change the Gravity to zero.

I even happened to have a cruddy airplane model sitting around, so here's a

(I just replaced my file with an update, as the "bullets" weren't rendering. Had to change Particle Source to Emit from FACES)
