[CustomShaderDrawFloat]
; The vertex shader passes constant buffer indexes to the geometry shader:
vs = draw_ini.hlsl
; The geometry shader generates the text for a given draw index:
gs = draw_ini.hlsl
; The pixel shader draws the font:
ps = draw_ini.hlsl
; Allows us to use SV_Position.z to pack a texcoord, increasing the character
; limit per geometry shader invocation:
depth_clip_enable = false
cull = none
; Enable alpha blending. To change the text colour, edit the pixel shader:
blend = add one inv_src_alpha
; Use points as the primitive from the vertex shader to the geometry shader:
topology = point_list
run = BuiltInCommandListUnbindAllRenderTargets
o0 = set_viewport no_view_cache bb

; Font is passed into the pixel shader (to draw it) *and* the geometry shader
; (as the character sizes are encoded in the final character of the font):
gs-t100 = ResourceFont
ps-t100 = ResourceFont

; Change this number to set how many entries are drawn:
draw = 2, 0
