Projectile Hit Detection

xAndrewx · #1 04-08-2012, 01:43 PM

When a projectile is fired (using shoot) and hits a wall on the serverside it calls this function in the Control-NPC

HTML Code:

function onActionProjectile(x, y, shootparams) {

but then the bullet doesn't disappear from the client. It still carries on flying past, even though it's hit an object.

Check the screenshot- the bullet hit the tree (fire starts on impact of hitting the tree on the serverside) but the bullet is still flying past.

Does the tree have the same setshape both clientside and serverside? I think I remember issues with this when setshape was used both serverside and clientside with different values.

I was under the impression that server-side hit detection is irrelevant to what the client actually sees since the client is basically simulating the shot on their screen, so if the blocking isn't the same on the client-side you'd see scenarios like that.

This is correct.

It not just happens on objects, it also happens on players too.

No real fix then? :[

I don't think it's broken..? As has been explained, you probably have different blocking policies on serverside than clientside (e.g. noplayerkilling on clientside but not serverside, different shapes on serverside, etc).

Would be nice if there was a command to make players blocking/not blocking for projectiles. As it is now, scripting your own projectile system is mandatory if you want to have non-blocking players on clientside.

You can use noplayerkilling on clientside, but then players can walk through other players, which may not be what you want. I really do wish we had more customizable projectiles.

noplayerkilling on clientside makes projectiles behave different on each players screen, since every other player will be non-blocking for them. It creates some very annoying situations for an online game.
