Games how would you create a blood splatter in game?

[ilan]

dont wanna just draw sprites on the screen i would like it to be random so any idea on how to do it?

something like this: http://shotgunfunfun.risingsunlegacy.com/home/

thanx

EDIT: B4j Example in Post #9

with just some randomizing math you can get some good splash results but in your example link it's more like a smudge/smear effect.

here's something I wrote a few years ago (the delay is because it's drawing out of the capture screen it draws instant and animated)

Thats really nice. I will do some checks to see how i can implement it using a game engine we have in b4i and b4a

you can find splash brushes for photoshop aswell maybe you can make a sprite sheet of it and randomly select one.

i think the best result you can achieve with a particle system.
it is just a list of particles, each paint a small picture
and all are updated each frame in rotation or position.
they will be removed after time or out of screen or if limit is reached the oldest will removed from list.

Hi, any chance we can have a glimpse at this code ?

 

[sorex]

the main animated drawing loop is just this, Martin.

For x=particles.Size-1 To 0 Step-1
 Dim p As particle
 p=particles.Get(x)
 p.x=p.x + Cos(p.angle) * 4
 p.y=p.y + Sin(p.angle) * 4
 p.size=p.size - Rnd(1,3)
 cvsSplash.DrawCircle(p.x,p.y,p.size,fx.Colors.From32Bit(p.color),True,0)
Next

the question is how the particle object looks like. is it a type object?
can you post a complete project that show how you did that animation. it looks really nice.

 

[sorex]

yes, it's just a type and you can see from the source what it contains and that's just x,y,angle,size,color.

the animation is the previously posted code in a timer, that's all.

maybe I'll post a project file later but it's part of an unfinished project.
