Ephraim's WML questions

[Ephraim]

Hello!

I was working on a map with some magic tiles that teleport you to a nother place (just a moveto with teleport unit and a lightning sound). But, I was thinking so hard and I realized that if I add an animation to this magic event, it will be better.

The idea is: when a unit enters in the hex, an animation of a lightbeam and an animation of the light star (the one that appears when you teleport a silver mage) will appear at the same time. When the animation finishes, there will sound a lightning and the unit will be teleported.

How can I code the animations?

Thanks.

The teleport animation uses a mask and does not need to depend on the unit's sprite, so it's quite doable.

You can use an object (possibly a temporary one) to add the teleport animation to the unit. Then you active the pre-teleport animation with animate_unit, use the teleport action tag to move it to the other location and then use the post-teleport animation to make it land there. You can add the lightbeam to the teleport animation as well.

I have been working on that, and I've got this:

Code: Select all

[event]
name=start
[object]
    [filter]
	    canrecruit=no
	[/filter]
	{TELEPORT_EFFECT_OBJECT}
[/object]
[/event]


[event]


name=moveto
first_time_only=no
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
[sound]
name=lightning.ogg
[/sound]
[animate_unit]
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
flag=pre_teleport
[animate]
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
{MISSILE_FRAME_LIGHT_BEAM}
[/animate]
[/animate_unit]
{TELEPORT_TILE 49 51 38 56}
[scroll_to]
x=38
y=56
[/scroll_to]
[animate_unit]
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
flag=post_teleport
[/animate_unit]
[/event]

But it doesn't work. What can I do?

[James_The_Invisible]

[object] is applied only to first unit that matches the filter, no all those units. If you want to apply it to more units, you should store them to a variable and loop over it ({FOREACH ...} ... {NEXT ...}).

I have changed the code for work in just one unit, but it still doesn't work:

Code: Select all

[event]
name=start
[object]
    [filter]
      [filter_location]
             x,y=4, 2
      [/filter_location]
   [/filter]
   {TELEPORT_EFFECT_OBJECT}
[/object]
[/event]


[event]


name=moveto
first_time_only=no
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
[sound]
name=lightning.ogg
[/sound]
[animate_unit]
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
flag=pre_teleport
[animate]
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
{MISSILE_FRAME_LIGHT_BEAM}
[/animate]
[/animate_unit]
{TELEPORT_TILE 49 51 38 56}
[scroll_to]
x=38
y=56
[/scroll_to]
[animate_unit]
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
flag=post_teleport
[/animate_unit]
[/event]

The location is the starting location of the unit, because it is the leader of the side but he can't recruit.

[enclave]

try
[filter]
x,y=4,2
[/filter]
without location.. and dont make spaces before numbers.. not sure if it matters, but it may..
I'm not expert about objects so no idea if it can help.

Have you actually seen the definition of macro TELEPORT_EFFECT_OBJECT? It is:

Code: Select all

#define TELEPORT_EFFECT_OBJECT
    # Creates and assigns a temporary object which applies the generalized silver mage
    # teleport animations to the primary unit
    #
    # For example, to apply teleport animations to the unit that triggered a 'move_to' event:
    #!{TELEPORT_EFFECT_OBJECT}

    [object]
        silent=yes
        duration=turn

        [effect]
            apply_to=new_animation

            [animation]
                apply_to=pre_teleport
                {TELEPORT_OUT_ANIMATION}
            [/animation]

            [animation]
                apply_to=post_teleport
                {TELEPORT_IN_ANIMATION}
            [/animation]
        [/effect]
    [/object]
#enddef

. That inserts [object] which is added to primary unit in an event. So it might be a good idea to remove the additional [object] tag and use the macro in your moveto event.

Ok, it worked! Thank you! And how can I add a lightbeam that falls over the tile that triggers the moveto (at the same time that the pre_teleport frame)? (49,51)

Code: Select all

[event]


name=moveto
first_time_only=no
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
[sound]
name=lightning.ogg
[/sound]
{TELEPORT_EFFECT_OBJECT}
[animate_unit]
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
flag=pre_teleport
[/animate_unit]
{TELEPORT_TILE 49 51 38 56}
[scroll_to]
x=38
y=56
[/scroll_to]
[animate_unit]
[filter]
[filter_location]
x,y=49,51
[/filter_location]
[/filter]
flag=post_teleport
[/animate_unit]
[/event]

[Dugi]

Add the lightbeam frame sequence to the animation in the object. See how it's done in core/macros, in one of the files about animations.

[Ephraim]

Yes, now it works! Thank you!

[Ephraim]

Hello again! I'm going on with the lightbeam and I want to change its color: from white to green, red, blue and brown. How can I code that without using an image editor program?

[Pentarctagon]

ImagePathFunctionWML - I would guess BLEND().

Hello!

I wan't to do the following:

The unit enters in a shop. Then, there will be a menu that allows this unit to buy some upgrades, like more damage, more HP, etc. But, each unit can only buy X number of upgrades of each one, for avoid making units invincibles.

So, how can I code that? I'm worried because if I use some variable like "number_hp", this variable will stand there for all the units, but I want that every unit has his own variable, that lasts all the game.

Thanks!

[Ravana]

Within each unit you can store variables to names such as unit.variables.something. And after changing it unstore unit.

[Ephraim]

So, the code shoyld be like:

Code: Select all

[option] 
label= +8hp
[command]
[modify_unit]
[filter] 
x=$x1
y=$y1
[/filter] 
max_hitpoints=+8
[/modify_unit] 
[set_variable] 
name=unit.variables.hp.upgrades
literal=+1
[/set_variable] 
[/command] 
[/option]

Or maybe is different than that?
