Access to DrawCircle, DrawLine, etc.

[crispweed]

Does anyone know why DrawCircle(), DrawLine() etc. are sim mode only?
(Search for these here: https://www.dropbox.com/s/7jpdpptw3ygonwb/fa.lua.globals.xlsx?dl=0)

These seem like exactly the kind of thing I would expect to be able to use in a UI mod.

It turns out that it is possible to draw circles, by using decal textures, as shown by the "Additional Camera Stuff v3.2" mod, but it seems crazy to have to use these kinds of work-arounds.

Should we be looking at adding access to some of these functions, for UI mods, instead, e.g. by adding a sim callback (if this is something that would be possible)?

My bet would be that it's drawing them for all players as it's in sim. While UI things you expect to show only to one player.

let me know if you ever figure this out, i've wanted that since forever

the best I can think of is terrible: you could make your own drawLine etc by making an opaque Bitmap for each pixel

In my current mod, I'm using a sim callback to draw a target for one of my unit ultimate strike. The target is driven by an emitter and as speed said, it is seen by everyplayer. The good thing is that you can do very cool effects and some fun because everybody sees the target when you move your mouse

A pure UI solution may be using vector GetMouseScreenPos() with a Ui object (bitmap for example), sync the Ui object coord with mouse ones and convert it to map coordonate...

Maybe using a circle bitmap and stretching it.

If it's sim only, how then do things like radar and range circles work per player? What am I missing here?

[Franck83]

Good question. Maybe hard coded ?

[nine2]

Things like radar ranges etc are not drawn by lua code. It's done in c++ code. There is no way for lua to invoke that circle drawing code.

Lots of things are like that when you are modding supcom. You want to do something that the engine can do ... but it's just not exposed to you.
