Trip mine script

[Xwad]

Hi is it possible to make a script that will make an explosion when a player hit an object? becaouse i will make a trip mine. Thanks.

[xXMADEXx]

Yes, it's definitely possible.

Instead of doing it so when you hit the object, you should create a small colshape around the object, this way you will be able to use the onClientColShapeHit event.

Use these functions:

getElementPosition 
createColCuboid 
createExplosion 

[Enargy,]

createObject 
createColSphere 
createExplosion 
onColShapeHit --- when players touch Sphere

You were fastest

Thanks:D I will make it tomorow. One question: if I make a colsphere then wil the players see it on the map?

[ALw7sH]

no, but you can create Radar-area in the same position of the col shape

so players can see it in radar

[Xwad]

i made it but only the createObject is working:/

  
function Mine(thePlayer, matchingDimension) 
createColSphere ( -1467, -1467, 99.15, 1 ) 
local pX, pY, pZ = getElementPosition ( source )   -- get the player's position 
createExplosion ( pX, pY, pZ, 6, source )   -- and create an explosion there 
outputChatBox("You stepped on a Mine!",thePlayer,255,109 ,109 ) -- outputs a chatbox 
end 
addEventHandler("onColShapeHit",root,Mine) 
  
  
function Object ( name ) 
createObject ( 1211, -1467.2827, -1287.6701, 99.15, 0, 0, 0 ) -- this creates an object 
end 
addEventHandler ( "onResourceStart", resourceRoot, Object ) 
  

[ALw7sH]

the col shape should be out the hit function

function Object ( name ) 
createObject ( 1211, -1467.2827, -1287.6701, 99.15, 0, 0, 0 ) -- this creates an object 
colShape = createColSphere ( -1467, -1467, 99.15, 1 ) 
end 
addEventHandler ( "onResourceStart", resourceRoot, Object ) 
  
function Mine(thePlayer, matchingDimension) 
local pX, pY, pZ = getElementPosition ( source )   -- get the player's position 
createExplosion ( pX, pY, pZ, 6, source )   -- and create an explosion there 
outputChatBox("You stepped on a Mine!",colShape,255,109 ,109 ) -- outputs a chatbox 
end 
addEventHandler("onColShapeHit",colShape,Mine) 

[Xwad]

not working:/

bad argumentum @ 'addEventHandler' [Expected element at argument 2, got nil]

[ALw7sH]

function Object ( name ) 
createObject ( 1211, -1467.2827, -1287.6701, 99.15, 0, 0, 0 ) -- this creates an object 
colShape = createColSphere ( -1467, -1467, 99.15, 1 ) 
end 
addEventHandler ( "onResourceStart", resourceRoot, Object ) 
  
function Mine(thePlayer, matchingDimension) 
    if source == colShape then 
    local pX, pY, pZ = getElementPosition ( thePlayer )   -- get the player's position 
    createExplosion ( pX, pY, pZ, 6, source )   -- and create an explosion there 
    outputChatBox("You stepped on a Mine!",colShape,255,109 ,109 ) -- outputs a chatbox 
    end 
end 
addEventHandler("onColShapeHit",root,Mine) 

[Xwad]

its not working only the createObject and no debugscript.

[ALw7sH]

Make sure that your colshape positions is right

you can use this command showcol

[Xwad]

the command is not working. But how can i set the height and the width??

[ALw7sH]

you should enable the DevelopmentMode using this function setDevelopmentMode before you use the command

then use the command like that

showcol 1

[Xwad]

i enabled and its not working:(( But can i not set the width and the height for the colosphere?

[ALw7sH]

the command is working but you cant see the colshape because the colshape position is worng and you cannot choose the width and high

you have used sphere colshaope

anyway try that code it should works fine

function Object ( name ) 
createObject ( 1211, -1467.2827, -1287.6701, 99.15, 0, 0, 0 ) -- this creates an object 
colShape = createColSphere ( -1467, -1287.6701, 99.15, 2 ) -- the last argument is the size of the colshape 
end 
addEventHandler ( "onResourceStart", resourceRoot, Object ) 
  
function Mine(thePlayer, matchingDimension) 
    if source == colShape then 
    local pX, pY, pZ = getElementPosition ( thePlayer )   -- get the player's position 
    createExplosion ( pX, pY, pZ, 6, source )   -- and create an explosion there 
    outputChatBox("You stepped on a Mine!",colShape,255,109 ,109 ) -- outputs a chatbox 
    end 
end 
addEventHandler("onColShapeHit",root,Mine) 

[Xwad]

WTF not working!! no debugscript nothing i dont know whats the problem!! pls help. Is it server side??

[ALw7sH]

yes, it's server side

[Maurize]

local mines = { { 1211, -1467.2827, -1287.6701, 99.15, 0, 0, 0 } }; -- all mines over here! 
  
addEventHandler( "onResourceStart", resourceRoot, -- if resource started the function starts to work! 
function() 
for i, v in ipairs( mines ) do -- loop the table above. you can add more mines if you add more data { { id, x, y, z, rx, ry, rz }, { same here and so on } } 
    local mine = createObject( v[1], v[2], v[3], v[4], v[5], v[6], v[7] ); -- lets create it 
    setElementData( mine, "mine", true ); -- lets set a data to remember it is a mine 
    end 
    setTimer( 
function() 
for i, p in ipairs( getElementsByType( "player" ) ) do -- loop through all players and check position 
    pX, pY, pZ = getElementPosition( p ); -- get position 
for i, o in ipairs( getElementsByType( "object" ) ) do -- loop through all objects and check position 
if ( getElementData( o, "mine" ) == true ) then -- check if it really a mine and not for example fence 
    oX, oY, oZ = getElementPosition( o ); -- get position 
if ( getDistanceBetweenPoints3D( pX, pY, pZ, oX, oY, oZ ) < 2 ) then -- now lets see if player is near enough 
    outputChatBox( "Kaboooohm! Mine over here!", p, 255, 0, 0 ); 
    createExplosion( oX, oY, oZ, 6 ); -- more realistic if explosion comes from mine. 
                    end 
                end 
            end 
        end 
    end, 1000, 0 ); -- lets check every second if someone is near mine. 
end ) 

untested but should work

[Enargy,]

it work perfectly. (tested)

function Object ( name ) 
setElementCollisionsEnabled(createObject ( 1211, -1467.2827, -1287.6701, 99.1, 0, 0, 0 ), false) -- this creates an object

untested but should work

for i, v in ipairs( mines ) do 
-- code 
end 

'ipairs' only works if the table has string, as fair i know. you must use:

pairs 

[Xwad]

Enargy its working! Thanks! And thanks for all answer thanks:D

[Xwad]

wait its not demaging i think its becaouse my spawn script!

[Xwad]

yes its becaouse my spawn script!! So i used SetElementHealth for the script but dosent work

            createExplosion ( pX, pY, pZ, 6, thePlayer )   -- and create an explosion there 
             if ( theHealth < 100 ) then  
            setElementHealth ( source, theHealth - 70) 
            outputChatBox("You stepped on a Mine!",thePlayer,255,109 ,109 ) -- outputs a chatbox 
        end 
    end 
end 
end

local theHealth = getElementHealth(thePlayer); 
if ( theHealth < 100 ) then
