Hi Everyone,

I've just tried to add a particle emitter to my code for the first time, and it sends everything absolutely screwy. The emitter appears okay but it also covers the screen with horizontal and vertical lines in the same colour as the emitter. See the attached screen shot.

The weird thing is all the particle emitter demos work just fine and the emitter creation code is just the same as in the demos. I am only using one camera, and the camera is set to defaults.

Has anyone encountered this problem/bug? Can anyone recommend a fix?

Many thanks,
Mr Grumpy

I've investigated further.

The screen flicker lasts for approximately 1 sec and then disappears. It rotates with the camera as if it is produced by two orthogonal planes one in front of the camera and the other lying on the y coordinate of the emitter.

The vertical and horizontal lines disappear after 1 sec, however, a second spurious, flickering plane occurs just in front of the emitter (see arrow in attached screen shot).

I've tried recreating this error in the particle demos, but have been unable.

GrumpyOne just checking, do you have a phy update before every sync you have in your code?

Hiya HowDo,

Yes there is only one sync in the code and it is immediately after phy update. I will bear this in mind though for when I debug using prin, sync, wait key sequences.

I've actually made a little headway. I've reduced the effect by (1) ensuring I set my graphics mode before a phy start() and by using "set object radius emitterobj, -1" after making the emitter. The flickering anomalous planes are now much less noticeable, but regrettably still there.

try the phy update 0 at the begin then update 1 at the end. might do the trick.
