【實用生產應用app】Particle Editor Phone Version|最夯免費app

This is the Android (phone) version of Matt Bennett's particle editor (http://www.matibee.co.uk/wpsite/), written using GLBasic (as usual).

I've had to reduce the text size and what-not to make it usable on a mobile device, so it may be a bit tricky to use.

Maybe I'll get around to doing a tablet version at some point in the future.

The various edit boxes are :

Point weight

The “weight” of each particle. Negative values will cause the particles

to rise. Positive values will cause them to fall.

Point scale Min / Point scale Max

The range for the scale of each individual particle when it is spawned.

Scale factor

The factor by which the particle scale changes every second.

Rotation factor

The factor (in degrees) by which the particle rotation changes every second.

Emitter Cone

The angular range of the emitter. An explosion might use a full 360° whereas a booster rocket might use just 20°.

Emit Min Distance/ Emit Max Distance

The distance range a particle will spawn from the actual emitter position (in pixels).

Velocity Min / Velocity Max

The velocity range for each particle as it's spawned.

Red / Red Factor, Green / Green Factor, Blue / Blue Factor

Each color channel (RGBA) has an initial value and a factor by which it can change over one second.

To start with full alpha, Alpha = 1.0, to fade alpha over 2 seconds, Alpha Factor = 0.5

Particles “die” when their alpha value or scale drops to zero.

Burst Count

The number of particles emitted per “Burst”. Bursts are usually restricted to 20 per second to ensure frame rates do not affect the

particle emitter results.

X Handle / Y Handle

The handle position for the image. Important if the particles rotate.

Note that the GLBasic value usage is slightly different to the original, whereby this is value is now an offset from the centre of the image, rather than from the top-left of the image

Alpha Blend

This is another difference - the sign of this value is used to define how alpha bending is used. For values > 0, additive alpha blending is used, for < 0, Interpolated alpha blending is used whilst with 0, no alpha blending is used

Alpha Factor

Speed that the alpha value is updated

Image file

The bitmap file used to create the particles. Only PNG files can be used

All the original example files are included.

Click on "SAVE" to save your settings in the Particles directory, "LOAD" to load them in, "IMAGE" to select a graphic (this will overwrite the current one), "UPDATE" to update any modified values (this is needed after changing anything) and "BACKGROUND" to select a background...

Saved files can be transfered to a PC for use in your own programs.
