Problem with Lua

[NG2]

I have a problem with the lua object:

for example:

I write DoCall("MakeEnemyJump",3) which tells the enemy to jump 3 pixels high.

But here's the problem: I want it to jump by letting MMF2 read the code script.

I mean something like this.

If EnemyCollidesWithBackground
DoCall("MakeEnemyJump",3)

Can anyone help me out ?

If Enemy collides with a background object:
..... Set y position of enemy to (y position of enemy)+3

You don't need Lua, you do it with MMF actions.

I think the "OnFunction" event can help with this.

Thanks but actually I want to write the code outside MMF, so that it can be executed in MMF's runtime.

Basicly I want to write a condition using Lua, so that it can be executed as a MMF condition in the runtime.

robbie* Yeah I tried many combinations using that event but none worked.

If I understand what your post correctly, you definitely need to use the "On function" condition- are you sure you are trying to use it correctly?

On function "jump"
  - set Y position of enemy to (Y position of enemy)+LuaValParam( "Lua object",0)

and then in lua

DoCall("jump",3)

[NG2]

I know that part, what you're showing me is the event that is triggered when MMF find DoCall("jump",3), what I'm looking for is how to trigger that event, using Lua.

Thanks anyway !

[James]

You are being very unclear- in that example, Lua triggers the MMF event.

[NG2]

Sorry
I'll try again:

That event is executed when MMF finds DoCall("jump",3) , right ?

So I want that event to be activated by lua, so that MMF knows when to trigger the event/function.

[James]

But it is activated by Lua. Whenever you do DoCall("jump",3) in Lua, it triggers the condition in MMF.

Is this anything like what you want?

Lua script:

function SpacePressed()
result=DoCall("test")
if result == "true" then
  return true
else
  return false
end
end

if SpacePressed() then
DoCall("add",1)
end

Events
* On function "add"
- Return "true"

*On function "add"
- Add LuaValParam( "Lua object", 0) to counter
