1)how do i change damage of reaper grenade (or the height of the bump, or other characteristics)? i can't find where the data for this ability is.
2)i don't know how to change via triggers the data of a unit. I have found the " set unit property " action, where in place of "unit", i put "value from data Table(unit)", and then i have to put a string of the unit i want to change, which doesn't work.
it looks like this :
Set ("Reaper" from the Global data table) Life to 100.0
i would assume it changes the reaper life to 100 but it doesn't.
The damage is an effect, "KD8 Charge Explode Damage" which is linked to "KD8 Charge Fate", that one is a behavior.
So go into the effects panel (add Effects as a pane in your data editor to access it), search for "KD8 Charge Explode Damage".
The field is called "(Basic) Combat Amount:" which has been set to 10 by default.
Navigating the editor tree is useful to find this stuff, Abilities link to behaviors which link to effects and movers, validators, and so on, based on the names you can infer what they do, and search to check their parameters to find what u r looking for.
I think the knockback is a mover, so find the mover (in the movers tab on the data editor) called "KD8Charge (Unnamed), looks like the parameters affecting the knockback is called "(Basic) Movement - Motion Phases +" and another one for the falling back down called "(Basic) Movement - Restore Height Duration"
I guess just play around with those stats and see if u can get it how u want.
Also to set the life of a single reaper, or a group of reapers in game with triggers is easily doable, setting the property of life of the last created unit, or unit from unit group, or even a pre placed unit. If you want to just modify all reapers life I suggest to change that within the data editor.
In the unit section of the data editor, just change the life starting amount, and life maximum, you can also change regeneration rates there.
I will add something interesting, some abilities aren't even abilities at all, like ones that involve regeneration, such as Combat Drugs, its just a high regeneration rate, and a long activation delay for life regen, all within the parameters of the unit itself. Same with burrowed roaches, they have an icon for the ability, but really a burrowed roach is just a different unit with a higher regeneration (all zergs that burrow are actually 2 units! Same with terran flying buildings, or morphing units)
