plane bombing script

[Xwad]

This script makes possible to drop bombs from planes. My problem is that the bomb is not exploding when its velocity is 0 pls help!

I can't find errors, except that the code will be bugged, when used by multiple users at the same time.

Debug your code! Check if the speed is actually 0!

if vx+vy+vz == 0 then 
--... 
else  
   outputDebugString("Velocity: ".. (vx+vy+vz)) 
end 

Line 27: null doesn't exist in lua, but nil does.

Use locals! and store them inside with tables or elementdata. You script serverside, so tables or elementdata's are required when you use the script for multiple players!

I got no debug:( i edited a little bit the script but its still not working:/

Or is it possible to blow the vehicle when its hitting a world object?

[IIYAMA]

Or is it possible to blow the vehicle when its hitting a world object?

https://wiki.multitheftauto.com/wiki/On ... eCollision

Possible, (there are some vehicles that don't work, especially planes)

See my bug report: https://bugs.multitheftauto.com/view.php?id=8265

[Xwad]

And is the event also triggering if i am not inside the vehicle? I dont want it for plane, i want it for the car "alpha" (id: 602)

Try it.

Wow zoRRoM! onVehicleDemage is a very good idea! the only problem is that its exploding immediatelly.. maybe becaouse the object is demaging it?

[Xwad]

Now i have edit it and its working but its not always exploding cuz sometimes the vehicle does not take any demage:/ for example if i drop the bomb from low height.

[undefined]

Add it for high damage.

setVehicleHandling(p_tbl.fallveh, "collisionDamageMultiplier", 10) 

And add it to disable collisions.

setElementCollidableWith(p_tbl.fallveh, p_tbl.missle, false) 

[_DrXenon]

Maybe use getElementSpeed, it is a useful function, If not, Try attaching a col shape to the missle and whenever any element hit sthe col shape that is attacjed to the missle, MISSLE blows.

I Hope i hepled.

[Xwad]

Good idea i try it thanks!

[Xwad]

the onVehicleDemage is not always demaging so i tryied to make it with attaching a colShape to the missle. The problem is that its not creating the exlposion when the col has been hitted.

  
function shapeHit() 
if getElementType ( targetElem ) == "object" then 
local x,y,z = getElementPosition(veh1) 
createExplosion ( x,y,z, 10) 
end 
end 
addEventHandler ( "onColShapeHit", col1, shapeHit )

Multiplier elements doesn't contain GTA worlds.

Ohh okay
