Help me!

[Sclammerz]

Hello. So, here's my problem how can I order a unit to cast a item base ability. More specifically I want a unit to cast a ability based on Scroll of Haste. Tried searching on google didn't help me much. So, help me out!

 

[Dr Super Good]

Only possible with direct JASS script (custom script) and must be done using order ID and not order string.

From that we can see...

    public constant integer scrollofspeed=852285

Hence the custom script to issue the order.

call IssueImmediateOrderById(udg_regunit, 852285)

This line uses a global variable "regunit" of type unit to specify who the order is issued to. Set it before using that line of custom script in a GUI trigger.

Many thanks. Dr. Super Good I'll try and test it out.

Not what he is after?

how can I order a unit to cast a item base ability. More specifically I want a unit to cast a ability based on Scroll of Haste

To clarify. He has an item ability, made it a unit/hero ability and gave it to a unit for casting from the command card (or whatever). Order strings do not exists for such abilities.

Wand of Illusion is a famous example where people want to create mirror images of units without going through the debuff cycle and invulnerability that Mirror Image does. If one has a dummy unit with it you cannot cast it without using an order ID. The order ID is also not immediately obvious, in fact the only way to obtain it is either through experimental testing (printing the order ID in game while manually casting from the command card) or by debugging the game code (reverse engineering).
