Crashing when emit is present

[bartando]

Hi, I'm trying to create a falling snowflakes but my app crashes whenever i use the .emit function
this is my code

@OverRide
public void onClick(View arg0) {
new ParticleSystem(this, 80, R.drawable.snowflake, 10000)
.setSpeedModuleAndAngleRange(0f, 0.1f, 180, 180)
.setRotationSpeed(144)
.setAcceleration(0.000017f, 90)
.emit(findViewById(R.id.emiter_top_left), 8);
}

i have the emiter_top_left and snowflake in the xml file so that shouldnt be the problem. Snowflake isnt any big image so that shouldnt be it either. Could you help me please?

Hi,

Can you post the stack trace of the crash?

By looking at the code everything looks right, and the examples work fine with similar code, so without the stack trace I don't think I can do much.

You said snowflake is an image, that is fine. It must be either a BitmapDrawable or an AnimationDrawable, so shapes or other xml drawables will crash, but that should not be your problem (actually you don't need the snowflake in the xml, just inside the drawables folder).

The other possible problem is that emiter_top_left is null, but you said it is there, so not much else can go wrong...

Mmm, a divide by 0. This is clearly a bug, but I'm not sure when I'll have time to fix it.

One more question: Are you using the latest code or the jar file?

Anyway, in the meantime, you can bypass this bug by doing

.setSpeedModuleAndAngleRange(0f, 0.1f, 179, 180)

Instead of:

.setSpeedModuleAndAngleRange(0f, 0.1f, 180, 180)

I remember fixing this or a similar divide by 0 issue, will need to check in which version the crash appears.

Am i supposed to choose between jar or the code? I thought both are needed

Ok i did it with the jar and it works pefectly. Thank you .. i was bit confussed ... now you can close and thank you for your help... :) 👍

You can either add the jar file OR checkout the project to add it as a library, you don't need both.

Apparently this is an issue introduced recently, so I'll keep it open until I fix it again.

Thanks for the report!
