The idea is that when an enemy is killed, a flow of particles moves from the destroyed enemy to the player.

I've done it with this code, but it isn't good, the movement is not good.
Can you help me to do something better? I've used particles, but i would like to use the "beam effect".
This is a demostration of my work as you can see, the movemen't isn't "smooth".

Hello!

First of all, I still don't know anything about particles, so if I say something that doesn't make any sense jsut ognore But aesthetically maybe I can help.

My first impression was that the particles were in a perfect line and all of the same size. A few patterns I can think of:
-Make the first one bigger and the following gradually smaller (with random oscilations);
-Also, change the opacity so that the last ones on the line are barely visible (making the opacity oscilate a little could work too)

Also, you can try to make additional layers of particles to achieve some sort of glow effect. Or even sparkles leaving the main trail in random directions.

I'm about to start playing around with particles too.. isn't there some sort of particle editor? it's hard to come up with something visually appealing only with coding.

I remember a tool that was in the site, something that show in real time the particles and instead put the velocity, the size and other proprieties.
It can be really usefull.

However my problem is't the particle, but the movement of them, thx for the help.

I know this might not help for a variable/dynamic particle method-- but nonetheless: a great tool for particles for Gamestudio:

Does Easy Particle only produce C- Script code and not Lite-C ?

The interface looks superb

thanks

This is a remake of Easy Particle done by Tobias and is referenced in the Lite-C contribution area.

It outputs Lite-C.

I still can't understeand how I can do this sorta of parabolic movement, someone have an idea? can help me?

Ooh! You want a better trajectory? is that it?

You can achieve "some sort" of parabolic movement simply by making the velocity vector of the particle always pointing at the player. To give it a little more movement, make the velocity vector's amplitude increase gradually, this way the particle will "fall" a little (to the bottom of the screen) before gaining velocity towards the player. (This is known as the predator-prey model)

Another possibility is to make the player something like a sun and the particle a tiny planet. Of course, you're not using the physics system, so you have to code this interaction yourself. But it's not difficult! Basically, you have to make tiny incremente to the particle's velocity towards the player per time unit (it's slightly different from the first approach). To make this solution more like a sun-planet system, make the increment increase with the distance to the player.

I don't know squat about coding particles, but at least I know a little about physics yay


edit: ...make the increment decrease with the distance... Because we want the particle to get more accelerated as it gets closer to the player.

Thx for it, but can you explane me how to set a vector from the destroyed enemy to the player and move one object towards it please?

You 'ent_removed' the enemy, of course. But do you need the enemy position for that? I thought that trail of particles was some sort of new entity, and we had to use the head of it as the position. You're supposed to work with the particle's velocity.
