Trace coming out of a bomb

[Machi]

Hi to everyone!

Well i have been looking at your forum for a few months now, found it interesting and decided to post my first topic. I have been playing with the objects.rfa for some time now, making a Mod to help instruct pilots on basic piloting skills like bombing and strafing. I have done the bomb make a trace of smoke, so i can see where it landed and how the trayectory was. The thing is the trace only works when i can see the actual bomb flying, like using chasecam when dropping it or quickly changing from nosecam to another cam where i can see it. if i keep in nosecam, when i drop the bomb and after it has impacted, the trace is not shown.

here is the code:

Any ideas?

I would guess at increasing the timeto live ObjectTemplate.timeToLive CRD_NONE/0.1/0/0 within the Em_PanzShootTrail but there are a couple of effects pro's here who will be able to help.

Additionally, when droppoing from very high or rockets etc shooting a long distance you can also find the actual projectile will vanish too at far range. This can be resolved by creating a custom bbox mesh for the projectile. Make it 50x bigger and then projectiles will be visible as far as the eye can see.

Ahh yes i forgot to tell how the code works. the panzertrail3 is actually a straight line drawn to show the actual "direction of fire" at the instant you drop the bomb. The panzertrail2 is the actual trace of the bomb.

i´ll put an image showing both emitters:

[fo0k]

ObjectTemplate.colorRGBAOverTime 0/255/0/0/99|90/255/0/0/70|100/255/0/0/0

Perhaps change that final 0 alpha value to 100.. (and the 70 in the middle too)
It may be that it it stil on screen but if alpha is zero then it will not be visible. Worth a shot..

I ll try it, but i think it has to do with the actual entity from which the smoke should come from (i dont know if that is the bomb or the emitter attached to the bomb) being out of the screen. Seems the only way to make it spawn smoke and leave its trace is to make it appear on screen.

Is there any page that shows and explains emitters and all the special effects on the engine? MDT is out, it had something explaining them...

I also wanted to ask if a weapon can shoot two different types of proyectiles at the same time, so i could spawn a bomb and another entity with the same characteristics but with no explosion nor damage falling with it.

Thanks a lot! ill try use this to solve the problem

[Dennis|8749236]

add another Firearm with same fire input on the firearm u want fire 2 kinds of projectile...
===========
and too see where the bomb hit... theres another way...
edit the explosion effect : add a smoke or some effect which can live longer into the explosion effect...

I think i tried the first, but didnt worked.... i also tried the proyectile2 thing but no result...

the second one is a good idea, ill add it to the mod.

A quick look at your code and I spotted that you didn't have looping turned on for either of the emitters

Code: Select all

ObjectTemplate.looping 0

Change it to this

Code: Select all

ObjectTemplate.looping 1

Also how is the effect tied to the projectile? Instead of addtemplating it to the projectile, try this instead:

Code: Select all

ObjectTemplate.startEffectTemplate (name of your effect)

This is how my trail effect is coded for tank projectiles in my BFH mod. It works in all view modes:

Code: Select all

Should make a good comparison to what your trying to do.
